Download online scanners from kaspersky or quick heal and scan your system for virus. Install a good antivirus, anti spyware and a firewall for your system at the earliest before your system is damaged beyond repairs.

You have a problem which is file association, you need to set back your registry to default state and fix file association.

WAssociate 3.4.3
http://www.xs4all.nl/~wstudios/Associate/index.html

or

Open NOTEPAD and copy/paste the text that is between the dashed lines (including the last blank lineI.
Then, do a File > Save > Select ALL files and save it "somewhere" with a REG extension. IE: FIX.reg

Then double click on the file to add it to the registry.

This "should" get your EXE's back on the air and allow you to complete the virus check.

In as much as I don't want to nitpick, telling someone to format their pc without exhausting possible remedies is irresponsible.

As per Akshay's advice, do an online scan. If you're still unable to to get rid of the infection, resort to using live CDs. They're godsend.

For starters, you can try using GDATA 2010, KAV rescue 2008 or dr web live cd. I'd suggest using Dr web though coz KAV scan time is painfully slow.

UBCD4WIN or Hiren's is also a good alternative, while they're not meant for a full virus scan, they're very good when it comes to repairing unbootable PCs.

Then install a good a antivirus+antispyware combo.
