Think you have Spyware?
Please follow these steps:
1) Download and install Adaware SE => http://www.lavasoftusa.com/support/download/
    And replace the reference file with the latest => http://download.lavasoft.de.edgesuite.net/public/defs.zip
    Run the program, and use the "full systemscan"

2) Download and install Trojan Remover => http://www.simplysup.com/tremover/download.html
    Download and install both the program and the reference updates => http://www.simplysup.com/tremover/update3.html
    Run a full scan

3) Arm yourself with Hijackthis => http://www.aumha.org/downloads/hijackthis.exe
    Normally I would suggest you to post the log at an analize site, but this time I'm asking you:
    Put hijackthis in it's own folder, NOT in any Temporary folder or on the desktop (something like c:\hjt\hijackthis.exe will do fine)
    Run it, read and accept the first warning.
    Click "Scan" and then "Save Log"
    The logfile will appear in notepad, read through it, make sure to remove any reference to your domainname or IP addresses.
    Then, post the rest of the logfile here and I'll take a look at it.
