I have installed ZeroSpyware LE (freeware) and it found (?) quite a few registry entries it categorized as spyware (i.e. Adware, Browser Hijacker, Chronic Spyware, Commercial Keylogger). It has the option of Quarantining these items, which I did. What was very surprising to me was that these items were found when my other antispyware programs (a substantial line-up) did not find them. Just one example: It found a CWS, yet I have CWShredder which did not. This concerns me, as it points to the possibility of a potential high rate of false positives (or, conversely, this is a heck of a program). Reviews on the net are mixed, which some concerns relating to false positives. I am looking for comments from members with experience with this program.
