I'm new to all this and am struggling with 'about:blank' and 'linklist' because I can't prevent them from taking over my home page. To date I have downloaded CWShredder, Hijack this, killbox and process viewer. I have also downloaded all the Microsoft updates. All without the desired result. I am trying to download Spywareblaster 3.1 but when I go to run the appication I get the following message "This program has been damaged, possibly by a bad sector of the hard drive or a virus. Please reinstall it". To be honest i'm not very sure what I'm doing and I would appreciate any advice.
