Problem when I try to enter a game lobby

Grimm is correct. With all those infections in the system no doubt they have created anomalies that your anti-malware program cannot pick up. Your only option to have a normal operating system is to install Windows from scratch (clean install). I'd recommend you back up any data that you don't want to lose (after installing windows again you can copy that data back). Try to format the entire hard disk. Create one partition and install windows on it. Trying to fix up a system that has had that much infection and showing the symptoms you describe is not worth bothering to repair, plus you'll be a lot more happy with a fresh copy of windows to work with.

I was a big fan of multi-partitioning some time ago, but it started to piss me off and now I just back up all of my data on DVDs prior reinstall. I guess it's a matter of personal preference there
Anyway, yeah, format is the only sure way of getting rid of malicious software.

Holy cow, lets not go off the deep end.

So you had a few malware infections, so what....you got them cleaned and you're off and running. You've picked up a problem that may or may not be associated with that cleaning so before you start ripping that machine apart, how about we fix the problem first then you can reformat your hard drive and spend a few days getting things back the way you once had them if you're that ambitious

Start by cleaning your system while it's in safe mode, this ensures you have no non-essential devices running while you scan. Boot the computer and just before you see the Windows Splash screen, hit the F8 key (repeatedly) until you get a menu allowing you to boot into Safe Mode. If you are given the option to log in as Administrator use YOUR normal logon name anyway. If you decide to log in as Administrator, your computer will make an unnecessary account that you don't need. You ARE the administrator so using your own account will do just fine. Once you're logged in under Safe Mode, run your malware cleaner and when you've finished cleaning up, reboot normally.

Now you need to get the proper video drivers for that machine. I'm assuming it's a toshiba laptop or something like that. It's important to have on hand the drivers supplied from the manufacturer if that's a laptop. Normal catalyst drivers can cause all sorts of problems on laptops. Once you get the video drivers downloaded, head to control panel / Add Remove Programs and uninstall the ATI drivers from there. If you don't see them listed, you can uninstall the drivers from device manager by rightclicking on the video adapter and selecting "Uninstall". If given the option, delete the drivers as well as uninstall.

You may be required to reboot at this time and after rebooting, cancel any hardware wizards that pop up trying to install drivers. Now run the setup program you downloaded from your laptop manufacturer which will install the video drivers. One more reboot and you're in business.

Note: Sometimes you have to uninstall the video drivers from Safe Mode. As a habit, I ALWAYS uninstall my video drivers from within Safe Mode to be sure I get a clean uninstallation without any remenants left behind. If you have any problem booting up without the drivers loaded, reboot into Safe Mode and install the drivers from there.

You might need the serial number on the bottom of your laptop to imput at the manufacturers website in order to get the correct drivers for that machine. I can't stress enough that you have the proper drivers before you begin removing the existing drivers.

I would also look into any other updated drivers your manufacturer might be providing while you're there. It's a good practice to keep your eye on any updates concering your rig.

The system has been compromised. There is no need to waste time on cleaning it up, it cannot be trusted anymore.
