I have a vista PC that when i try to load malwarebytes,cc cleaner or super-anti spyware programs.These can be loaded but when i run them they closed down.I can load them and update them.Although once you run them and they shutdown you find the icon on the desktop has been changed(the path has been removed)???? The message says this program has been changed and removed. I have ran AVG 9 and it found a few trojans which it removed and i rebooted but the same thing is happening. If i could stop Malwarebytes from shutting down i may find a virus,i have also tried loading these programs and updating them,and turning the wireless off,buut still it is happening ,help appreciated. I have checked the account and it does have admin privilages,although when i tried to load super-antispyware i got a message saying "i did not have sufficient privilages to change the program".Yes its got me baffled also. This might have nothing to do with the above but also when trying to update windows i am getting error 80070005,this might have nothing to do with the above.
