I would recommend downloading and installing AVG 8.0 to do a full system scan, you can download it off this site, or if you dont wish to install anything..
You might be able to use an online scanner, such as the Windows Live onecare - http://onecare.live.com/standard/en-gb/default.htm?mkt=en-gb&s_cid=WL2Hdr
I downloaded Malwarebytes from this site and installed it into my computer, but when I go to use it nothing happens. It is fully installed and in my Start menu.
I have not been able to get updates from Ad-Aweare since December 9th. I get a message that tells me that I am not connected to their server.
I have the go.google.com trojan what redirects my searches on Google.
