Please do this. Click here: http://www.sherrylynn.us/HijackThis.exe to download Hijack This. Save it to it’s own folder (not temporary files or the desktop).
Close all open windows and open HIJACK THIS. Click “Scan”. When the scan is finished (it only takes a second), the scan button will change to “Save Log”. Click on “Save Log” and save it to NotePad. Copy the entire log and paste it here.

DO NOT FIX ANYTHING YET, most items that appear in the log are harmless or even needed. Wait for someone to analyze the scan and advise
