Hi,

  • you don’t have all Windowsupdates → APPLY them
  1. → install, update, scan & fix with Ad-aware, spybot and cwshredder
    from http://www.lurkhere.com/~nicefiles/index.html & www.lavasoft.de

  2. check all (Startup-)entries in HJT-Log if they are malicious or useless,
    and fix them if so…
    → with Log-file from Hijackthis
    http://www.spywareinfo.com/~merijn/htlogtutorial.html (english tutorial) in combination with:

a) database http://www.sysinfo.org/startuplist.php or OFFLINE: http://www.pacs-portal.co.uk/startup_pages/start_ups.exe or
http://www.windowsstartup.com/wso/search.php & http://www.reger24.de/processes.php & www.google.de
b) KAV-Scanner (see below)

reboot…

if problems remain, tell us exactly what you did so far, and post a new Hijackthis-Log :wink:
