Okay, I've been running tests the past few days with Prevx, and it indeed blocks most of the viruses and worms. But what's up with the Fake AVs? Any comments about these? The protection seems to be lacking here. Prevx only detects at most 1 out of 10 new samples. Shouldn't the age/popularity criteria (both set at max) stop these new samples from compromising my system? And in most cases you won't even see Prevx working down in the right corner of screen (it seems the fake AV passes right through the protection). Here's an example: WARNING!! DO NOT CLICK LINK!!!!! ~Link removed. No links to malware on the forum.~ It just went right through, with all heuristic settings at max. That fake AV even managed to shut down Prevx.exe. I'm very concerned about this. Oh, and yeah, I did report the very same sample via e-mail to Prevx.
