Regress
Behavior like this from any AV company is deplorable if it really is being done. There used to be lots of people submitting the stuff I get mostly in my email now to the AV companies via VirusTotal. I can remember when Hispasec Sistemas was running VirusTotal. I used to give my samples to any AV company that wanted them via back channels. I do it primarily through VirusTotal now. That way I can leave a comment and a negative vote that may help somebody.
With as much bad stuff as we have now it would seem like any AV company large or small would spend their time at doing better analysis and not worrying about how other AV companies are doing things. Any time some AV company does these things they harm everybody but most especially themselves. Do you want an AV product where that company spends time bad-mouthing other AV companies or one that works harder to both avoid FPs and at the same time handle the tsunami of malware headed people's way?
Contrary to popular belief, malware on Linux takes a different route. Any excutable Linux binary saved from either website or email is saved with the execute bit off. It won't run until you manually chmod it so that it will run. So desktop Linux systems if there are any left are basically immune from binary malware. They are open to abuses with JavaScript add-ons to browsers. Mostly what you have are exploit kits to take advantage of daemons on the servers and then rootkits to cover the infiltator's presence after they get in. But then a fine AV company like eSet has their sales staff try to sell their product liike Linux is just like Windows; it isn't. I have two machines named gandalftw and sauron. They trust each other just about as much as the real ones in LOTR. If I was rich I would love to have eSet NOD32 on both of them. The hang-up is a GUI that is sufficiently powerful, provides me with xterms with a NavajoWhite1 background and black text, four virtual workspaces, and once it gets to where it needs to go it just becomes a matter of refinement. Instead they try to come up with iPhone GUI wannabees. I am still running with Gnome 2.x because all of the other newer GUIs are unsatisfactory. I will give KDE one last try but I fear that GUI too will be gone in less than 2-3 years.
I see Windows 8 machines where everybody has a doorstop in nine months flat. Almost every Windows 8 user I know has that problem. Windows 10 seems to be headed the same direction. So what we have is regress instead of progress and AV companies shooting themselves in the foot. Avast, stop installing the Chrome browser with your free product. I don't want it on the Windows 7 side of my machines. Why is Windows 7 there? The ISP install staff don't know what Linux is. It is too bad Linux will be gone entirely in five years because the idiots think you want a Macintosh or iPhone GUI on the Linux desktop.
