Answer 1

This sounds like one of those freak accidents. (like when the rubber bands on my braces came off when i was eating a sliced apple) ANYWAY!!!! UnHackMe is a great tool to find and remove Trojans and Rootkits. Trojans and Rootkits are designed to be well hidden so antivirus programs such as Norton can not detect them. If all else fails call Geek Squad or reinstall Vista. Your computer should have came with a Vista Reinstallation disk. Dont get gung ho about reinstalling though because you will want to read up and have a proffessional (if you can) reinstall it for you.

O.k first thing is first most times you may need some more memory or download malwarebytes http://www.malwarebytes.org/ and install, get updates then run a full scan. After that restart your computer start pressing F8 and choose safe mode and run malwarebytes again in full scan, repeat until it doesn't find anything. But I guarantee it will.

Download Internet Explorer to your hard drive and reinstall it. It's the best and safest way to fix corrupt internet explorer files.
