Did you just get redirected from web sites such as google.com to bakaav.com?
If so, I just wanted to let you know that it happened to me too on my lab machine, and that the problem was solved by removing three adware programs. The adware I removed was called TinyWallet, BlockAndSurf and BrowserWarden.
Hope that helped you solve the problem.
What adware programs did you find on your machine?
Thanks for reading.
i will remove bakaav a.s.a.p.
Thanks
