Thinkpoint? virus

I believe I got the Thinkpoint virus [from something off the Yahoo homepage, maybe? I did the classic user error of clicking on something without thinking. If I'd been thinking, it wouldn't have happened.]

Malwarebytes' Anti-Malware got rid of whatever it was, but now my machine is in a deeply strange state.

I have to right click on executables and "Run as" . Anytime I click on [for instance] my Firefox shortcut, it asks me what program I want to use to open it.

Anyone seen this before?

So you think you're a hero, huh.

Short version is the underlying system was hijacked; Explorer has been compromised; and file associations have been changed.

Reinstalling programs such as FireFox should reset their particular file associations.

You can also reset file association and program defaults in Windows 7 under: Control Panel\All Control Panel Items\Default Programs\Set Default Programs

I would also put your Windows installation disc into the drive, then go to the command prompt and run: sfc /scannow

That should reset any modified Windows system files.
