Virus removal question?

I have this virus on my computer that occasionally redirects me to other sites, usually domainsa.com, but this virus only affects my Google Chrome browser. I've tried several different virus removal techniques and software (always trustworthy ones) but so far nothing has helped. Currently I just did a scan using PC Tools Spyware Doctor and it found several threats on my computer, but now I found out that while you can have your computer scanned for free, you have to have an actual account and pay to have them removed. No other program that I have used so far has actually found any threats, so I was wondering if there was some other way to delete the threats the program found than by paying for it.

Also, if anyone could possibly recommend any other ways to get rid of this annoying virus, that would be great. :)

First thing is uninstall the PC Tools Spyware doctor and restart your computer. After restarting go through the control panel - Add/Remove programmes, find the unnecessary programmes that installed on your system. Check them and uninstall them as soon as possible and also uninstall the Google chrome. If you have installed antivirus please uninstall that too. Restart your computer.

If you know that infected with virus or ad wares  malwares, I would like to suggest the free edition of avast antivirus or If you can afford buy Norton Internet Security Software's  It is an Excellent security software. But don't forget to remove the unnecessary programmes from the system. After Installing Antivirus perform a whole system scan of your computer.

Some ad wares programmes automatically installed from the adwrare sites, beware while opening of these sites. If you have installed Internet Security it alerts you that you about to visit a malwares site or ad ware site. So you can know what's happening?

My suggestion is don't install pc doctor or pc tools anti spyware or spyware removers. Install a good Internet Security software's for better performance of PC.
