back to article AVG fake traffic spares Google AdWords

Yes, AVG's LinkScanner is spewing fake traffic across the internet, messing with the log files and bandwidth budgets of web sites large and small. But there's one thing it doesn't mess with: search engine paid clicks. Used by roughly 20 million people worldwide - and counting - AVG's new security tool scans search engine …

    Why?

    I may be being dumb here, but what's wrong with scanning content *when it loads*?

    I'd reckon malware could detect if the page is being invoked through adwords and fire, and hide itself otherwise. Which defeats the point of the AVG product.

    I've turned this off, and now get a pling in my toolbar. More of this and I might even pay for a non-AVG virus scanner.

    Security theatre, I reckon.

    Why not scan "onClick"?

    I assume im missing something.

    But why not scan on the Click instead of when the link loads?

    Sure, you would have to detect any false Clicks (incase some sort of malware is spoofing them and loading things through the backdoor etc etc).

    But essentially what I am saying is that is there something so harmful about some links, that merely looking at their existence will somehow render your computer virus ridden?

    If not then there has to be a more intelligent, less intensive way of filtering.

    Even if a link says "Cheap cameras. 100% REAL" and it leads to a malware site, then surely you can intercept it later on IF the user tries to click it. Or even wait until a mouseover event. or something.

    I assume there is a genuine sensible reason, so can someone please inform me.

    Solution

    Simply find out the lowest level vuln AVG picks up, put it into the webpage, such as a link to a bad site , javascript approach, anything that just about pulls the trigger for AVG.

    Webmasters on a few major & minor sites put it in, AVG correctly scans and reports the risk, pissed off user, good result for owners. Plus they can constantly update by checking with AVG what triggers it, and implementing that as a dummy false positive.

    Work around

    What about....

    Im assuming Linkscanner doesnt go to the trouble of loading things like images too.

    So. A work around would be to exclude all html visitors that dont also load the images on a page, or things like that.

    Yeah you might lose a few (developers who insist on turning their image loading off or whatever) but otherwise, wouldnt something like that work? ish.

    Freedom vs. Security

    The problem with this is essentially the same problem that plagues proponents of freedom-preserving workarounds such as anonymisation services. That is, if a site protects you from the prying eyes of Big Brother, it also by default protects paedophiles and scammers. For example, if an image hosting site provides total anonymity for posters of images who might be unjustly victimised by their government (eg a Chinese dissenter posting a picture of Tiananmen Square), that site will invariably be abused by kiddy fiddlers, spammers and scammers for their own nefarious ends. Compromise the site's anonymity to catch the scumbags, and you make it possible to catch justified dissenters as well.

    This AVG Linkscanner faces a similar problem. If it makes itself identifiable in any way by a legitimate webmaster to save bandwidth costs, that means of identification will invariably be exploited by scammers and malware purveyors as well.

    This holds true regardless of whatever technique one can come up with, simply because it is impossible for any technological system to ascertain intent in this context. Certainly, organisations like DARPA might try to come up with ways of "reading intent" by scanning peoples' faces at an airport, but in reality, this technology is unreliable at best and dangerous at worst. And such technology is unlikely to become widely available any time soon.

    So it will be interesting, in the face of this dilemma, to see what "solution" AVG comes up with. If they do, they will also have solved one of society's greatest and currently unsolvable issues - that of Freedom vs. Security!

    McAfee vs AVG

    McAfee's SiteAdvisor relies on a database of sites and pre-existing scans. AVG's LinkScanner performs a real-time analysis of the results of a search query.

    It does not load images in a page, and the only request seen is that of the actual page link returned. I have tested this on my own sites and viewed the logs.

    The advantage is real-time scanning of potential threats. It also means that you do not go to a page with browser exploits which may otherwise bypass malware protection to "pwn ur b0x" unless you ignore the big red warning about the page.

    Not only annoying but soooooooo slow.....

    I have used AVG anti virus for many years, until this latest release. After installing it my PC slowed to a crawl and surfing the web was a painful experience because of this new "wonder" feature (amongst others). I immediately disabled most of its functionality, then wondered why I should keep it installed in the first place. So AVG has gone to the giant bloat-ware repository in the sky - (Much like an experience with a Norton update a couple of years ago). I'm trialling Avast and think it does a good job without the bloat and system hit. So maybe the current "fake traffic" problem will only be a temporary glitch, before most people switch to a leaner more efficient solution...?

    AVG is acting like Norton/Symantec

    I hate AVG 8 so far. It uses up a lot more memory than 7.5 did.

    Also, I think LinkScanner is stupid, annoying, and wasteful. It wastes my bandwidth and CPU resources as well as the websites'. I disabled it. Well, sort of. If you disable it, the tray icon shows that AVG has a problem. You either need to install AVG without LinkScanner or (as I have done) disable the Firefox add-on (within Firefox). That way, AVG acts normal because it doesn't know it's not working, and I don't generate tons of extra traffic (not to mention those annoying green checkmarks).

    There's another issue that leaves me quite disappointed: Famatech's Remote Administrator. AVG 7.5 treated it as a normal program. AVG 8 treats it as spyware (just like Norton/Symantec), so you need to go into the PUP (Potentially Unwanted Programs) and exclude the RAdmin files (in the Program Files directories and the Windows\System32\RServer30 directory). I'll go out on a limb here and guess that neither Norton/Symantec nor AVG consider PCAnywhere a potentially unwanted program, even though it does the exact same thing (just with a lot more bloat).

    What are the criminal implications of LinkScanner?

    Perhaps this is a conspiracy-theory type of thought, but what are the criminal implications of using LinkScanner? For example, let's say you use Google to search for porn. LinkScanner will then automatically retrieve each of the returned results and scan those pages for malware. If one of those result pages was being monitored (or was a honeypot) for child pornography, it's quite possible (some might say likely) that your IP address would be logged, your ISP subpoenaed, and you would soon get a visit from your friendly law enforcement officials seizing your computers and anything else they like. If they're in particularly good moods, they might even spread the word that you're a suspect in a child pornography ring. And let's face it -- if you're even mentioned as a suspect in child porn, the world acts as if you're guilty, even after you've been "found" innocent (on a side note, if you are presumed innocent unless proven guilty, why do they need to "find" your innocence?).

    All this in the name of "security", to keep malware off of your computer.

    @Darryl

    So quick to jump ship? Software vendors need feedback to correct problems with their software. Having dealt with AVG now for five years, I can confidently say that they value your feedback.

    I am using v8 with all modules enabled except AntiSpam (due to how Outlook handles IMAP accounts, messages get duplicated when captured.) On Windows XP SP2 and SP3, I see no decrease in browsing speed, whether I am using Firefox, Opera, Safari, or Internet Explorer. I am aware of an issue with Vista which is documented in AVG's support center as the first FAQ in the list.

    They are only trying to speed up their product

    At the expense of everyone else's bandwidth.

    And yes it does rather increase your exposure to leaving IP numbers left, right and center. People can correlate that information a bit as well. If you know where you are on google rankings, you can start to work out how much traffic a competitor may be getting who is top or top 3.

    Quite cheeky really, and borders on being malware.

    But, that is the problem, most security developers are not into creating things, they are into breaking them. Too many cracker wannabes go into security, when really they should be in pen testing, or fail to flip to the paradigm of creating useful software that plays well with others.

    Plot? Lost!

    This is why I've moved away from AVG on this version, the overpowering feeling that "Daddy knows best" - and it seems to be yet another example of a developer who's started hating its customers.

    You can spot the rot when it asks you to install the Yahoo! search bar, always a sign a backhander's been given somewhere. Even more damaging is that AVG forces the installation of a browser plugin even when told not to during install.

    This behavior is more like the malware it's supposed to be fighting; a crying shame when the engine and signatures are actually pretty good - but it does seem like the upper management are on some kind of crack-fuelled ideas-fest with no brakes.

    The link scanner is so obviously a stupid and bad idea it's amazing it even escaped somebody's mouth, let alone left the brainstorming session and into production, past quality control and onto our plates. That shouts to the world that *somebody* powerful in that company has made the cardinal sin of pushing their own agenda regardless of the damage it does to the company - and this HAS blemished an otherwise very good reputation for Grisoft.

    What about the impact this has on us without 8mbit connections? The web's getting slower and boggier for us *without* something else thinking it has a god-given right to lean over our shoulder sucking the bits away before we can even use them for ourselves. I have 512/256 adsl - it's the best I can get where I live; with link scanning on it's actually SLOWER than a 56k modem. Good job guys, really good job.

    this IS malware!

    1) It uses about 10 times the resources it did (assuming you get about 10 links back on a search engine).

    2) It tries to disguise itself as something legitimate.

    3) Despite a large group of affected people (webmasters so far) the makers want to make it it more stealthy.

    ...... yep that sounds like any other malware that i have ever come across.

    This is dangerous tech

    At the moment its easily identified which means it can be dealt with for 2 reasons:

    1) the good reason: reduce bandwidth, just serve up a basic page

    2) the bad reason: hide whats really there

    Either way, leads to a false sense of security to the user, since they assume its scanning the actual content of the page.

    If they make it more tricky to detect, then its going to have some dodgy implications, if it uses my user-agent and IP then essentially my details are stored on the webservers logs even if I didn't click the link. In all my time using google, I'm more than aware that even on basic searches for "computer memory", something messed up can sneak in.

    Because they want to tell users in advanced which link is safe. It can't pose as a user if an actual user is clickig it because it will probably load faster than the Linkscanner can scan thus missing any viruses or any viruses or malware or other crap will be received by the real user first.

    surely it is obvious

    Surely it is obvious that this is a really inefficient way of doing this. AVG should just have a central indexing server that does this, that all the clients running AVG then connect to in order to check if the search result URLs are flagged as problematic on the central server? That way a site only gets hit once in a while.

    Maybe there is some flaw with this I haven't thought of, but if it isn't practical AVG should just scrap the whole thing as it really is irresponsible.

    At the moment, webmasters, the deluded web analytics bofflets and the Law all assume that web access is driven by humans, who are there to be { counted | exploited | prosecuted } as required.

    I've been using the Fasterfox add-in to Firefox (2.0, doesn't work with 3.0 yet) which pre-fetches pages, and for years before that, when I was on dialup and Windows (I'm cured now) I used a little proxy tool, the name of which escapes me, which did much the same thing.

    Marketing Data and Landing Pages

    When a marketing department uses AdWords to handle their campaign they usually have a landing page for the product or service they are selling :

    www.blablabla.com?page=ourgoogleadcampaign

    If Linkscanner is filtering out the google side of tracking the click - they are not and cannot filter out the other side - the client side.

    Most marketing execs use page counters and time on page and click through data to determine how successful their campaign is. If they launch a big campaign and linkscanner is hammering the page but not clicking any further, nor staying on the site for longer than a few seconds - it could look like things are going REALLY badly.

    Just a thought...

    Wouldn't the best way to implement this system be to use a whitelist system of websites that were scanned regularly to ensure they've not been infected, say once a day at a set time.

    These sites would then not be scanned by the scanning tech everytime someone visits them. Then the scanning system need only be employed for sites not included on the whitelist like when checking out obscure Japanese porn sites.

    This way AVG users get the same level of protection and webmasters don't get bandwidth-raped.

    The only catch is AVG will need to fund the system for scanning the whitelist sites.

    Referral URL?

    In terms of web analytics, there are several factors to take into account.

    1. If the request has no referral URL, then it's going to appear as a direct hit on the site.

    2. Presumably all cookies are ignored so no Visitor matching can be done.

    This leads to an increase of bounces of unknown Visitors. Given a decent web analytics package (e.g. VBIS from Site Intelligence), this would be easy to discount by segmenting the data appropriately.

    The "beauty" of Linkscanner is that - every time you search - it reminds you of the protection in action.

    Remedy if you used to like AVG

    If you disable Linkscanner via the AVG interface it will show a constant warning icon in your tool tray. You can remedy this by keeping it enabled but disable the plugin via IE and Firefox.

    IE > Tools > Manage Add-ons > Enable or disable

    Firefox > Tools > Add-ons > Extensions

    If AVG thought this through properly the solution is for THEIR servers to do the scanning using both an on-demand and a cached method...

    Your urls are sent to AVG's server and if it has run a check on the url from its own server within the last 10 minutes it returns a cached result. If not then it hits the url afresh and returns that result. That way webmasters will only see a hit every 10 minutes, not every few seconds. The down sides are it will take slightly longer to do and your urls will be logged by AVG. Do you want AVG to know what you've been searching for?

    AVG need to make easier to disable Linkscanner without it flagging up a warning. The average Joe doesn't know how to disable add-ons. In fact, the default install option for Linkscanner should be "disabled", but obviously AVG wouldn't do that unless they are heavily pressured.

    Security Risk

    When I tried it, I purposely attempted to visit an infected site to see what would happen. First, the bad sites were immediately flagged as bad in Google results - the good sites took a few seconds to be checked. This would indicate that the bad sites get added to a database and then ignored for a bit, while the good sites have to suffer continuous scans.

    Then, when I clicked a link to a bad site, I saw an AVG page warning me that, if I attempted to visit the site without adequate security software, "Such as AVG", then I was leaving myself at risk of infection. Umm...hang on. Clearly I *have* adequate security software - that's what's warning me, after all. So where's the benefit of pre-scanning?

    Since we all accept that visiting certain websites can be a security risk, how exactly is my security helped when the very software that's supposed to be protecting me is visiting all these sites on my behalf?

    If a vulnerability in the scanning engine were discovered, a user wouldn't even need to visit an affected site to be infected. From their site: "AVG scans every Web link you come across, whether in e-mails, documents or instant messages, no matter the source, before you open them to ensure you are protected in advance 100% of the time." - so it would be enough for someone to send you a link in email or IM for you to be attacked.

    AVG realtime scanning

    Surely if AVG 8 was any good (not saying it isn't but just suppose), then it will need a 3rd party app to help it. If I goto a compromised site and it installs a root kit or whatever, then surely AVG should pick up on that as it gets installed ? If it is so stupid as to not recognise a virus then how would the linkscanner recognise that the site is offering a virus as a free download ?

    Belts and braces are only needed if one if a pile of sh!t and they can't ensure it works proper (fit for purpose springs to mind, especially for all those who pay for AVG).

    What I can't understand ...

    is why AVG insist on installing this Linkscanner by default. Surely it would be better as an optional extra and having the user making an informed decision during the AVG installation process?

    If the user says 'Yes' to the LinkScanner install question, a warning can be displayed telling the user of potential bandwidth issues, etc. Then if the user again replies 'Yes, I understand the risks' the installation of the LinkScanner goes ahead.

    If the user says 'No'' then no LinkScanner is installed.

    It's all pretty simple to implement isn't it Grisoft?

    Also, I think the LinkScanner should check against a database of known suspect sites and not blatantly check each and every one ad hoc. I removed AVG8 for this reason as it created so much unwarranted net traffic, my VirginMedia account was capped due to excessive use.

    I can think of two rather obvious reasons:

    1. Good website owners have been fooling LinkScanner ever since it came out by either telling it to check AVG's site instead of theirs (hilarious) or by feeding it a dummy file.

    2. Bad website owners have been fooling LinkScanner ever since it came out in exactly the same way so they can safely deliver drive-by downloads, and have been handed a database of AVG user IP addresses so that when the user-agent changes they will still be able to fool it.

    AVG was the first anti-virus that I voluntarily installed on my machine - although through work I'd had experience of Norton/Symantec and McAfee.

    They all sucked, and compared to them AVG seemed to be a "breath of fresh air". Now however, it seems as bloated & slow as the ones I've experienced through work - and therefore it's gone.

    So that's a "loyal" AVG customer that won't be touching their new products.

    I just hope that Avast! doesn't go the same route, I'm giving that a try now.

    Disable Vista UAC?

    An above comment mentioned AVG's FAQ at http://free.grisoft.com/ww.faq.num-1338. The last question is "1258: What to do when the AVG 8.0 Free Edition installation fails". The last suggestion is:

    "5. Disable UAC (Windows Vista only)

    On Windows Vista, the function User Account Control may in some cases create a copy of specific AVG files in a virtual folder. This limits AVG functionallity after the installation. The UAC function can be disabled in Windows Control Panel -> User accounts -> Turn User Account Control on or off -> uncheck "Use User Account Control (UAC) to help protect your computer" -> click OK button and restart the computer."

    So here we have a security product which is telling you to disable the built-in security features of the operating system. I understand people have issues with UAC (and Vista in general), but I find it amusing that a security product is telling you to disable security features in the OS.

    Day job: 475K page hits yesterday, 52K from the AVG UA; 11% bloat

    Personal client: 22K page hits yesterday, 3.75K from the AVG UA; 17% bloat

    Club 1 website: 3.5K page hits yesterday, 1.25K from the AVG UA; 36% bloat

    Club 2 website: 787 page hits yesterday, 462 from the AVG UA; 59% bloat

    Not even gonna say how I feel or this won't get posted...

    "a security product is telling you to disable security features in the OS"

    Surely LinkScanner should now flag AVG's site as a purveyor of malware?

    On second thoughts, LinkScanner is such a joke it probably does.

    I wonder what the Czech for "Roger Thompson - you're fired" would be.

    Paris - because if AVG made her chief of research she would do a better job.

    The firms website is geting a lot more hits and I know we are not that high in the rankings. Have recommended up'ing our hosting account. Have not run the fingerprint though the logs just guessing 50% is AVG.

    Click through counts are garbage anyway.

    I think AVG should be applauded for making advertisers reconsider the convenient fiction that is their business model. Maybe someone should make a Firefox addon to compliment adblock by simulating clickthroughs. That way no one has to see ads, content websites get payed, and advertisers get boiled in their own soup.

    Still wondering

    ... what in the world AVG was thinking. Surely they can't be dense enough to have not realized the potential impact of this linkscanner and realized that even if they don't care about the consequences that plenty of other people would.

    What I wanted was to just keep using AVG 7.5, but even that has become increasingly annoying with it's continual pop-up notifications about end of life and upgrade to version 8.

    It's really sad how some many software developers today think it's perfectly legit to erase all the gains we make in bandwidth and processing performance. Someone wrote we should upgrade the computer or something to that effect. Why? When using a browser, particularly doing Google text search, it's not doing anything that couldn't be done 10 years ago with a 300MHz processor based system. It is ridiculous to upgrade a computer just to keep doing the same things you always have unless it was too slow for that in the first place.
