Let me first start by saying that I have run hitman pro, spybot S&D, malwarebytes, windows security essentials, tdsskiller and a few registry cleaners. I detected some things and removed them then re-ran everything again. Every single one of the programs I listed came back the 2nd time as "no issues detected." I think my issues started happening when I wanted to run an old win 95 game and downloaded wings32.dll and put it in my system32. Bad idea apparently. So, I deleted it the other day, but the problems are still happening.
At times my PC is completely and totally unusable and at other times it works perfectly fine. I've been trying to narrow down the problem but I can't help but think that it might be a corrupted hard drive. Maybe you guys can help.
So, my PC ran fine for 1 day after I freed it of the viruses/malware and then the same problem happened again. Windows kept freezing and I noticed that several instances of conhost.exe, csrss.exe and dllhost.exe were running, and dllhost.exe in particular kept duplicating and re-duplicating, to the point where like 10 of them are running at one time.
Error messages have included the one saying windows installer is missing (it randomly got disabled even though I didn't disable it), some error about how task manager can't start and then it brought me to a completely black screen for about 5 minutes then back to my desktop, and some other weird errors I've never seen before (I'll tell you guys about them if I see them again.)
I am thinking it has something to do with the dll I put on my PC. I know it isn't meant for windows 7. Either that or a corrupted hard drive. Another thing I wanted to note is that my current window that I'm working in keeps randomly de-selecting, and I think that it only does it when a new instance of COM Surrogate (dllhost.exe) comes up. I have also noticed that at a certain point my PC seems to get to memory overload capacity and freeze, probably from too many instances of the 3 things (conhost.exe, csrss.exe and dllhost.exe). Do you guys have any suggestions?
