Thanks for the welcome and after 22 years working in this field one thing I've continued to do is listen I’ve never stopped learning. I still think (what to call them?) "Commercial Security Packages" belong in a corporate environment where there are more controls over the applications and OS privileges, and policies to govern over them. I think what drove me to my opinion about AV / security suites was more my experience with home use. Often the products completely consume the resources of the machine (sometimes even worse than malware) making legitimate applications run slowly. They also inundate the user with pop up messages and warnings, most of which are not understood, and often ignored or answered incorrectly. Let’s take my wife as an example. I’d call her your average social media sponge, with a fairly average appetite for online shopping....In the past year I’ve had at least three "AV Security Solutions" installed on her PC. I’ve had these products at various “recommended” security protection levels and spent hours whitelisting legitimate sites and applications. What I would call “good husbandry” of all the false positives she had uncovered. . I’ve tried various OS level account privilege settings, browser settings, NOSCRIPT addons, and other safe browsing techniques, but find many of them alter sites to the point of being broken and unusable or displayable, and many of their pages fail to function. To date she’s had Fake.AV infections at least six times, encountered countless undetectable droppers and key loggers.. The first few times she was infected I did some investigation as to how this was allowed to happen. When asked if the computer warned her about the activity I was informed she merely clicks on the boxes until they go away. So in the last few months I have resorted to Home Server with “working” images for each of my family member’s computers. When I come home from work only to be greeted with complaints about a computers performance or inability to browse the Internet I merely drop in a bootable CD and within minutes the computer is back up and running again.
