I have Avast free version. I recently had my email hacked. I ran several quick and full Avast scans which found only one virus which I successfully deleted. My email was hacked again. I then tailored and ran a "custom scan" for PUPs. The custom scan returned 81 viruses from "memory" that appear to be trojan horses and worms and most all with high security alert. Many of these items I have Googled and are well known as damaging. My Avast program will not allow any action to be taken with the "apply" button (delete, etc). I've since installed, and run several times, Malwarebytes, Spybot, Adaware, and Kapersky TDSSkiller, and I did a boot time scan with Avast. The Avast scans never find these same viruses unless I run the "custom" scan. Some different viruses were picked up by the other programs and sucessfully deleted - but none are any of the 81 viruses from the Avast scan. What gives? I've read other posts re the "apply" button issue. I either can't follow or clearly understand much of the protocol solutions suggested. For me, you'll need to really dumb down and simplify any suggested solutions. I would think that getting Avast to follow it's own program protocol would be a simple fix but I guess it is not. Please help and thanks in advance.
