I haven't seen the runtime error in a couple of days. I am assuming it corrected itself somehow.
Okay that's good to hear. If it ever comes back please post the specifics in your thread so the helper knows what to look for.
I think you're ready to go.
1. Remove previous restore points and set a new one to purge any malware that may have been backed up:
Click Start>Help and Support>Undo changes to your computer with System Restore
Click Create A Restore Point then click Next. Give it a name it and then click Create
Click Start>Run and type Cleanmgr
Click the More Options Tab.
Click Clean Up in the System Restore section.
This will remove all previous restore points except the newly created one.
2. In order to prevent future infections follow these recommendations:
a. Visit Windows Update on a regular basis to stay current with critical updates.
b. Install and run the following free programs:
* Ad-Aware SE

* Spybot-Search & Destroy

here! Please also remember to enable Spybot's "Immunize" and "TeaTimer" features.

A tutorial on using SpywareGuard for realtime protection against spyware and hijackers may be found here!
* IE-SPYAD puts over 5000 sites in your restricted zone so you'll be protected when you visit innocent-looking sites that aren't actually innocent at all.
Keep all these programs (including your anti-virus) up-to-date and run them regularly.
If you do not update regularly they will not be able to catch any of the new variants that may come out.
c. I recommend you to read Tony Klein's excellent article: So how did I get infected in the first place?
