okay well mine was getting shut down every 6 hours or so and after i changed that setting for the RPC it hasnt shutdown once.
So i suggest going thru the steps i mentioned earlier and set your computer not to reboot when the rpc has a problem.
I have read about a few rpc exploits like the ones mentioned/experienced.
I highly doubt that its coincidence we all have some sort of trojan worm virus problem etc along with the rpc problem, BUT that being said, From what i have read about rpc( remote procedure calls ) exploits the fact that the computer reboots tells us that the "HACK" wasnt succesfull.( kind of ,
it was succesfull in killing the computer but that prob wasnt the original intent )
Setting your RPC so it wont reboot when it has a problem hasnt seemed to cause any error and im watching closely !!
But just because we dont reboot doesnt mean there isnt something malicious still on our computer that we need to remove/fix/patch.
I will search around and if i find a perm fix i will let everyone know.
btw there is many variations to this problem/virus going around right now, so be sure to try all the suggestions mentioned even if your symptoms arent exactly the same. ( ask first if your unsure )
