Hi :

Would be wise to check the "Quality" of any antispyware product being used; in addition it is wise to use at least 2 antiSPYWARE/antiTROJAN programs since One program will NEVER detect everything. And as you experienced, should ALWAYS INITIALLY "Quarantine" any alleged "Detection", then investigate as to IF it MAY be a false-positive, like you are now doing on this Forum .

As to "ZeroSpyware" ; several yrs ago it was listed as a "rogue/suspect" program, by antiSPYWARE Expert Eric Howes, on his spywarewarrior Site. It was "removed" from that "category" in 2004; however, it is wise to use ONLY his "Trustworthy" products, which can be found at http://www.spywarewarrior.com/rogue_anti-spyware.htm#trustworthy . The "trustworthy" program we mostly recommend here is the FREE Version of "SUPERAntiSpyware", available from http://www.superantispyware.com/ . At a minimum, this program should be used as a "2nd Opinion" to the ZeroSpyware "detection". As already mentioned, UNLESS you post the EXACT Name of the ZeroSpyware "Detection", it is impossible to offer any trustworthy "Response" . In fact, most likely you should be contacting ZeroSpyware about their suspect "detection" . I recommend you use their "Live Chat" or "Email" available at http://www.fbmsoftware.com/support_main~sid~11176126~bttn~269.html .

I have seen nothing on the various Sites I visit that MS has a "built-in" keylogger in their Vista OS .

However, Dell saying they have no "spyware" installed in their computers is a "borderline" statement . Many people complain about their "My Way" program, which many in the Malware-fighting "community" consider "it" adware at a minimum and bordering on "spyware". In addition, Dell's "Search Assistant" ( most likely their "My Way" ) and "URL Assistant" is in the database of the highly regarded "PC De-Crapifier", available at http://www.pcdecrapifier.com ; I strongly encourage you to visit this Site and seriously consider using the FREE program there .
