I had the w32.blaster.worm in August and removed it via the symantec tool. I am getting the same svchost.exe errors again, but after running the worm blaster, it says I do not have the worm present. I also STILL cannot install either of the windows Service packs 2 or 4 so I can install the shield. I get a winlogon.exe error and the computer reboots immediately. Does anyone have a similar situation? I have tried just about everything 3 times now with no luck, including getting the Service pack 4 cd. I still get the same results at the same place. ANY help would be greatly appreciated. Thanks.
