Now, I tried downloading HijackThis.exe, as I was told to after my first topic on this problem. Downloading it froze my computer, which I found could only be resolved by rebooting. I tried to download HijackThis a total of four times, each time it froze, so I can't provide the logs that you guys ask for in this post.
My problems remain the same: My computer is performing sluggishly and slowly, and when I run Malwarebytes, it finds a total of 13 infected files, but cannot remove them, becase it freezes during the removal process, and when I attempt to do something else, even open the Task Manager, it freezes the entire computer. I've managed to get enough performance out of the computer to get online and post this problem here by keeping the Task Manager open and ending any malware processes that I find, but that is, at best, a temporary solution. What can I do to fix this problem? The only plan I can come up with is using Malwarebytes to get a log of all the infected files' names and locations, searching them out and manually deleting them while ending their processes simultaneously. However, this search and destroy method would be quite time-consuming, so I would really prefer an alternative solution.
