I checked the system with avast! Free Cleaner and with latest NOD32 at highest possible settings and nothing. I have installed SP1, MSBlast and Sasser patch,but i cannot access windows update because RPC fails before i can do anything (i can remove that countdown,but after i cancel it system becomes quiet useless without RPC service. Yesterday i was on the old Win installation with all possible patches and it was the same. I thought its SP2 beta issue,because i uninstalled it,but it appears that its not since i have the same problem on fresh Win installation.

Here is also a NOD32 log which shows files of Sasser patch. I don’t think its normal that they are not accessable. Or is this due to offline RPC service?

EDIT:
avast! Virus Cleaner shows the same thing (i didn’t see this on last installation when i performed scan!?):
