I have a laptop that has been totally ruined by the Software Distribution Service 3.0 update that has installed itself even when automatic updates are turned off. I can't do a restore to an earlier date because every date i have to retore from for the past 2 months has checkpoint and Software Distribution Service 3.0. My computer is extremely slow now and doing many strange things like shutting off after about 3 hours, wanting to do chkdsk after every startup, and bluescreen errors after a certain time...please help me remove this completely
