One of my computers have been taken over by what I presume would be a virus. I had Norton AV but it didn't detect it.
Unfortunately, I'm having a very hard time fixing it. It won't let me run HiJackThis, MalwareBytes, Search&Destroy or Norton AV. The only application that seems to run is SUPERAntispyware and I have to reinstall after a restart.
If I try to run the aforementioned programs, it seems to replace the .exe file with something else (or perhaps removes the .exe extension) but then it won't allow me to rename it (permission denied). Renaming the program .exe file (ie, renaming mbam.exe to cbam.exe) still causes the above. Running in Safe Mode does not change the outcome of this.
SUPERAntispyware is able to run and it has found and removed some Trojans but it seems to be having an issue removing this one. What should I do now?
