Smart sputnik

Hey guys. I recently tried to crack a verion of guitar pro and being the dips hit that I am I download a small variety of viruses. Most of which I've been able to handle, but there's one that wreaking havoc on my sanity. I've been using Chrome for a while now and so far apart from some lag issues that I'm going to attribute this to the only real issue it's given me is that it changed my default search engine from Google to some "smart sputnik" link and has apparently revoked my admin rights from chrome when I am the sole user of this computer. Any ideas of how I could get rid of this?

go to the above forum as there are no certified malware removal specialists here.

If it were up to me, I would completely wipe the drive and reinstall as that is the one sure way of removing all virus'

 

In future, dont try to crack, I got 2497 virus when I tried to crack NFS 2015 and MalwareBytes!
