Whenever I open a new tab in IE7 another IE window opens up with some advertisement. I have scanned my computer for spyware but nothing has been reported. Computer also seems to be running very slowly. Takes a long time to boot and freezes from time to time. Can anyone help.

Post a hijackthis log. Scan with Ad-aware.

Usually we ask you to visit this website: http://www.hijackthis.de/index.php?... where your logfile can be auto anylised. I've pasted yours into the anylizer and it didn't raise any definite flags. A couple of unknown objects that warrant further investigation but nothing openly malicious. I used to have a signature but it disappeared and I just couldn't be bothered writing another so please feel free to ingore this.

That was bad advice pgck... hijack logs are better posted as per response 4. Once I thought I was wrong, now I'm not so sure!
