Hi FreewheelinFrank,
I agree with your opinion completely. It is absolutely vital to stick to reliable anti-malware software, and the site you advised is the place to go for this information. The forum on spywarewarrior.com and the one at castlecops is very instructive. There are loads and loads of programs pretending to be anti-adware, anti-spyware, anti-trojan and lure you to download their scumware, good for many a false positive, clearing some malware out, and putting even nastier scumware back. Also some reliable scanners like bazooka leave certain adware out, because else they would have a courtcase on their necks. Bazooka has a list of adware and screensavers it does not scan for. But anyway it lists these omissions. The anti-malware world is a "shady"world for some indeed, just like the real world is. But when the spam-man works for the ad-man paid by the number of clicks according to the stat-man, what else would you expect to happen?
