Hi, My problem is that every website that I look at turns in to an ad.farm mediaplex web page with a whole load of links. As a result I am having to write this on someone elses computer. I have adaware and spybot and CWShredder and despite deleting everything that shows up on their scans I cant get rid of the problem. I have done online virus checks on symantec and they come up with nothing. I would appreciate any help as I need to use my internet and not someone elses. Thanks

More than likely it did not pick up the program(s) that reload it. If your registry is not cleared of it then usually there are some files within the C:\ or C:\Windows directories that the registry points to that will load it all back up. You should go through the scans delete everything. Also Try Hijack this and fix any other items you find, mainly BHO lines (browser helper objects). Then go to the registry and search for ad.farm delete any entries there. (make sure you backup the registry first) Also often you will think you deleted files that are in your startup section but they are not deleted. So check there also, goto Start-Run- Type Msconfig, go to the Startup tab and uncheck any files you do not want loading or do not know what they are.
