Thanks for your responses! Feels great that someone actually can help out when things are bad.
SP1 is corrupt? I actually downloaded it via Windows update and thought that should secure a correct version.
Anyway I tried to install SP1 manually via link but as usual configuration update ends at 30% and then a system restore is proposed. This time I also received message that automated repair was not possible because "patch is preventing windows from starting" error code 0x490 and yes one new folder "c:\428fd9af1e363f2ca811d6\.
- If SP1 is corrupt but downloaded via windows update does that indicate rootkit not removed during reinstallation of Windows?
- Best way to verify if I have a rootkit installed? (I scanned for rootkit with TDSkiller but nothing was found)
- Do I need to use list disk command "clean all" or is "clean" enough? (I understand clean all is not good for my SSD)
- I have also a secondary harddrive d: that I previous had Windows installed on. This disk now only include documents, pictures and programs not installed. This drive is not formated during reinstallation of Windows. Is there any way that rootkit could be activated on this drive if no programs are started?
- Other suggestions?
