I suggest you consider:

  1. Clean your temporary files from time to time: [ur=http://www.stevengould.org/downloads/cleanup/]CleanUp[/url] or the Windows Advanced Care features for that.

  2. Download, install, update and run other trojan remover tools: a-squared and/or Free AVG Antispyware (trojan removers). Some users recommend SUPERantispyware or Spyware Terminator.

  3. Besides the immunization of SpywareBlaster I suggest the Windows Advanced Care features of spyware/adware cleaning and removal.
