Hi, my girlfriends laptop has been running slow. I ran mbam and it said it found svchost.exe. Not knowing what it was at the time before I did any research, I just clicked remove. Now the I can't access the firewall (obviously because I removed it), and its just really slow. Any help would be much appreciated.
