Alright guys, I hope you can help me, my computer has already been fully clean of viruses and malware of the sort, so I'm going to need some other answers. A couple weeks ago, I cleaned my computer of malware and trojans. For some reason after that, I cannot launch most of my games and applications, and this specifically is tailored to most of my pirated games. It does happen to my legit stuff too. But for some reason, two pirated games lasted, and they were Bioshock and Civilization V. Another weird thing was one of the legit games that were affected was Team Fortress 2, and probably because two of the deleted pirated games I had ran the same hl2.exe process. Steam told me to delete some folders and files except for two things, steamapps (Which was a folder that contained my Steam games including Team Fortress), and the Steam.exe application. It surprisingly worked!
After some help from Broni (Thanks a lot for helping get rid of anything that was making my computer slow, and although it really didn't resolve my crashing problem, you've been a big help ), I got rid of every virus or something that made my computer slow. It didn't solve my crashing problem. What seems to happen with most applications, is that I launch them, and after a few seconds it says that "Application X has stopped responding.", or sometimes, the not responding doesn't even show up (This also applies to League of Legends, where the logo shows up and disappears.), it shows up in my process list, and just disappears. I already ran a system check and used tweaking.com's Windows Repair, it just won't launch at all. I dunno what's going on, but this seemed to start after that virus removal. Please don't move this topic to another forum like "Help! I'm Infected", because it's not that anymore.
The topic, if you want to know what probably was removed, is here: http://www.bleepingcomputer.com/forums/t/501906/help-me-with-malwareslow-problems/
The list of applications that I know so far that were affected are below:
League of Legends
Halo 2 (Pirated)
Counter-Strike Global Offensive
M2 Sega Emulator
Scribblenauts Unlimited (Pirated)
Sims 2 Double Deluxe with various expansion packs. One Expansion is pirated.
Nestopia (NES Emulator)
Others I probably haven't tried yet. I hope you can help me find a solution. I'm going on vacation tomorrow and I don't want to be game-less on the way...
