[QUOTE=SeÃ¡n;2744224]That’s actually an interesting read and definitely the first document I’ve seen on exploiting Antivirus products into running code or crashing out, like how a specially crafted PDF can cause vulnerable versions of Adobe Reader to run malicious code.
Although the document does not compare pro vs. free versions of an Antivirus product, I would imagine that if a hacker can trick the free version into running malicious code, the pro version is unlikely to be any safer, as it usually has the same processes as the free version, but with extra processes to cover the paid for Firewall, etc.
I was quite surprised that most antivirus products give the scanner process system level privileges, some even with DEP turned off for that process. All the hacker needs to do is exploit the scanner process into running malicious code and the malware automatically has system level privileges.[/QUOTE]
The problem here is if they update their PC hosts file to something I use this will also prevent pops/adware that could be infected from entering and thus giving the A/V a extra time to catch and kill the infections.
