My PC was infected with W32.Myzor.FK, so I purchased Spyware Doctor. This seems to have cured the problem, but my PC is phenomenally slow. Is there likely to be something still remaining? Is Spyware Doctor worth keeping or should I try something else? John Uttley
W32.Myzor.FK@yf is part of an attempt to sell you a fake anti-spyware program -- there are lots -- and it also tries to steal passwords. You should change yours. Many free programs are able to remove it, including Lavasoft's Ad-Aware and AVG AntiSpyware (formerly Ewido). To double-check your PC, download a new free antivirus program, reboot your computer in Safe Mode and run it, then reboot and run it again. You could also try one of the online scanners, such as Trend Micro's Housecall or Kaspersky Online.
PC Tool's Spyware Doctor is a well-respected program, and a cut-down version is included in the Google Pack software. It can be a resource hog, but as you've bought it, it's not worth paying for Webroot's SpySweeper as well.
Unfortunately, the free versions of AVG AntiSpyware and SuperAntiSpyware don't provide continuous real-time monitoring. If you feel you need this, I'd suggest using Windows Defender (formerly Giant AntiSpyware), and running Spyware Doctor from time to time to double-check it.
