Welcome to the forums.

A search of these forums for win32:startpage will no doubt return many hits as this topic has been previously discussed a number of times.

If you haven’t already got these other anti-malware tools I suggest you download them. startpage is a browser hijacker so requires a different approach.

  1. Ad-Aware
  2. Spybot Search and Destroy
  3. Download HijackThis.zip
