From what I can see on t'web, this seems like it should be relatively easy to remove. Follow the manual instructions on this site: http://www.411-spyware.com/remove-antispywarexp2009 and check everything is gone. I'd also check your hosts file. For XP it's at: C:\WINDOWS\SYSTEM32\DRIVERS\ETC. Right click on it and choose Open With Notepad. Check for anything you don't recognise. You can *usually* safely delete every entry in here. (Make a backup copy first in case I'm wrong!) You could try replacing the hosts file with one from here: http://www.mvps.org/winhelp2002/hosts.htm Delete your Temporary internet files and cookies, and then open a command prompt and type "ipconfig /flushdns" (without the quotes). You could also try googling for HijackThis, which is a tool that tells you what's running in the background. You can export the results and post them on the site forum and ask for help. If none of that works, I suspect a complete reinstall is probably going to be the quickest and easiest recovery method.
