I got a computer to repair that would not turn on and boot up. After manually connecting the hard drive and removing the viruses the computer now works. But, after another virus scan more viruses where found and removed now it seems the computer is working faster and better but after start-up I get different pop-ups advertising games and what not. One pop up directed me to the site (playsushi.com) Is their that I can remove those viruses and pop-ups without reinstalling? I am open to any suggestions: software, manually, deleting registry entries etc. Also sometimes after restart a password appears that I have absolutely no knowledge about and I have to restart the computer.
Thank you for your help
