Hoe do I fix my computer?

Every time I try to start a program, like Anti-Malware I get this:
“Choose the program you want to use to open this file”
FOR EVERY SINGLE PROGRAM!
And when I do I get this:
Application failed and some crap!
I have application tracking cookies (45 Infections)
Adware advertising (20 infections)
Rogue.AntiSpyware.Advanced Antivirus (6infections)
Adware Onflow (1)
Rogue AntiSpyware. Andvanced AntiVirus Pro
Trojan-Spy.Zbot Yeth (2 infections)
Trojan Diablo_keylogger (2)
Adware hotbar (1)
Trojan Fake Alert (25 infections)
Trojan Spy-Zot (25 infections)

What should I do!! I tried system restore, wont allow me, because of the Open Program With thingy. I basically can’t do anything! I tried formatting but I can’t!

By the Way i found all of those threats with spyware doctor, but i have to pay for removing them!
Someone help My computer is getting owned!

Try using MalwareBytes Anti-Malware, which is free & can be downloaded from here:

http://www.malwarebytes.org/

(or http://filehippo.com/download_malwarebytes_anti_malware/ )

Install, update it, run a scan (preferably full scan in safe mode), then remove whatever it detects.

Hope this helps & feel free to e-mail me if you need further help :)
