Re: Kaspersky PC "infected with loads of malware"??
1. No AVs are able to protect against 100% of malware, so things can get through
2. Apparently, the user paused Kaspersky for the initial malware infection, else Kaspersky would have blocked the infection in the first place - https://www.theregister.co.uk/2017/10/25/kaspersky_nsa_keygen_backdoor_office/
Why a security expert would trust using a keygen or cracked software on their live system is beyond me.
