Removed malware now can't open any programs. Help!

Ok so I recently had a virus on my laptop disguised as "Vista Smart Security". Using advice I'd seen from this website I used malwarebytes to get rid of it. This was successful but, second time round when the virus attacked again, I couldn't use run malwarebytes or rkill, neither would open.

So I downloaded Super Antispyware. At the time I thought it was odd that the scan found 929 infected files but nevertheless I sent them to quarantine. After the reboot however I'm left with an even bigger problem. I can't open any programs at all. Every time I try to open explorer a message comes up saying "Choose the program you want to use to open this file" And I try to select the right program and the same message keeps popping up.

I'm posting this from my PC (Thank god not all access to the net and help is lost), I hope there is someone out there that can help!

EDIT: Moved from Vista forum to Am I Infected, more appropriate forum ~ Hamluis.

If I were you, I would create a new Am I infected? topic to be sure all the malware is gone. 929 infections is a lot.

Thanks but this won't work either, command prompts are being denied.

You are probably still infected. Please post a in the Am I infected? What do I do? sub-forum with a description of your problem, the steps taken so far, and a link back to this topic (they will want to know why you suspect malware).

Please note: the Malware Response team are always overwhelmed, and it could take a few days to get your first reply. Just be patient and don't "bump" your topic by replying to it, as that will only further delay a response (MRT members are looking for topics with 0 replies...if you reply to your own first, it will appear that you are already receiving help and thus delay receiving actual help).

If you still have problems after being declared clean, they'll send you back here.

Good luck.
