Im very close to considering new systems I install to run with Prevx/SO as the sole resident security app (spywareblaster not withstanding.) I tell ya, I'm all but fed up with what I'm seeing from the top AV makers. Yes you too Microsoft! One product doesn't reliably update and has the support organization of a schizoid monkey with ADD. Another seems light contained and great - but interferes with dynamic disks, disk mounting and Hibernation. Another seems great til ya see how it shreds apart winsocks. Another I only have anecdotal info and my own subjective tests which is a great AV unless you move large databases of info or need to use Windows functions that page a lot of data really fast and then blammo - file corruption and errors galore. Then of course you have a few do nothings with pretty interfaces and bloated beauties that feel like carrying Sally Struthers home from a night at White Castle. "Pullin at my hair." I suppose a security app that makes it difficult to use the functions of your PC is certainly hampering malware, but gee, is it so much to ask an AV app to not break the full usability of a PC? I have one semi bloated AV I might consider if necessary. Haven't made up my mind (sometimes a lil bloat can be sexy! ... but I digress .. lol) Where on the spectrum of reasonable to foolish do you folks rate a decision to have Prevx/SO as the sole resident app?
