My parents computer is a little older, but it is running VERY slowly, and it is doing some bizarre things. Often times when trying to go to a website (such as the superantispyware site, it re-directs to a completely different site.
I downloaded Avast! antivirus (they did not have an active anti-virus before), and the computer will not completely boot unless I boot into safe mode (which is what I am in right now). I also downloaded Malwarebyte's Anti-Malware, but it quit a few seconds into the scan. I also downloaded Hijack-This, and it also quit a few seconds into the scan. Then, when I tried to reopen HJT, a window popped up saying "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.
When looking at the task manager, there are a couple of weird entries. helpctr.exe has 2 copies running, as well as a couple copies of something else that I stopped running (it had something about 7PFR something...) but since stopping them they haven't come back up. Any help would be greatly appreciated!
