OK I've been having this problem for a week or so.

When I click on some links going through Google, it takes me to "http://clickfraudmanager.com" page which then takes me to some weird places.

I thought it might be some malware, so I ran AdAwara and Malwarebytes as well as Avast Antivirus in Windows safe mode, but the problem still persists.

is there something wrong with my machiene, or has something gone drasticaly wrong with Google.

I run WinXP with Avast antivirus and Firefox as a browser of choice.

Any ideas?
