Hello GX1_MAN. I have this problem of the infected csrss file. I have deleted the one in the virus vault, scanned & repaired in safe mode, tried to replace/overwrite the file, yet I still get the message 'csrss application cannot be run in win32 mode'. Where have I gone wrong & what can I do next? I don't know much about computers, (but I'm learning!) so please give any advice/instructions in simple terms. Many thanks. :-?
