smitfraudfix log (can be found at the root of the system drive, usually at C:\rapport.txt)
Start pc in safe mode. Remove from file types dsk (tools/folder options/file types). Find core.cache.dsk (c:/windows/system32/drivers/) > right click > properties > remove archieve check > click read only > ok. Search for any recently suspicious programs created in search > when was it modified > specify date > created on (when infection suspected) .exe\\\\\\\\\\\\\\\’s and check publisher, delete if unknown of. Restart. Solved. Basically leaving it in read only mode disables it and renders it harmless. Happy surfing.
I also had Core.cache.dsk as a problem on my system but I stumbled upon a fix that worked for me.
I am by no means an expert on these malware issues but maybe someone here who is can
rationalize how I managed to clear this so simply.
What i did was this;
First i restarted the system in safe mode
second i found the Core.cache.dsk file
then i changed its file extension to .txt (Core.cache.txt)
I then opened the file with notepad and deleted its contents and saved it
then i changed its extension back to .dsk (Core.cache.dsk) and opened
the properties dialog and made it read only.
I downloaded the free version of Superantispyware and let it do its thing
and viola the system was clean even after several reboot checks.
I had core.cache.dsk, couldnt get rid of it. I just tried Kevins solution – seems to have worked fine. Only thing is when you boot in safe mode, I had to select safemode with networking inorder to sign on. Thank you kevin.
