im trying to fix a computer for a friend and its turning into a crazy nightmare. I have installed Malware bytes, amongst other programs, and none of them will work. Hijackthis is automatically shut down and then i am denied permision to use it, as well as advanced system care, spybot search and destroy, avira ( which wont even install) I ran tdsskiller(i think thats what is called) it detected it removed it yet i still have the same problem. When the virus stops the program the Icon on the desktop changes and wont run the program. I have tried changing the names and extensions of the programs and it does not work. I have changed hijack this' name as well, and the program still shuts down, then denies me access to the point where i cant even uninstall it, or delete it.
