PSA - Farking Computer

So, i'm currently having issues with my beloved Hyperion.

Apparently when i went to class today, the MSN i leave on, but away started spamming people like mad. If you're one of those people, I am truly sorry.
If you're not...well, I'm saying sorry for the future in case it does happen.

Basically you get some shit about a photo that i have or found of you on the web and you have to click the link. well, i'm not stupid - i know NOT to click the links. However, I have no idea why it's doing that.

I am doing various virus, malware, spyware, ad-ware and greyware checks. However, I'm not too sure if this will actually do anything or not.
Since this morning, Hyperion has been a little on the buggy side. I'll go to open a program and it hangs there. sometimes up to at least 5 good minutes before i get frustrated and flip it off and TURN OFF the power, which then it decides that it doesn't want to be off and just restarts.

i'm really hoping i don't have to get to the point where i have to do a system restore. i can't remember what the last date of a system restore was done! *meep*

Also, my Windows Updates won't turn back on, no matter what i do or from what area i try to reactivate it from.

so, if you get a message from hecatesbrat@hotmail.com with a link, and it's gibberish and you know it's not me, DON'T CLICK IT. okay? just don't.

any if anyone has any suggestions as to what i can do before i turn to the system restore, please let me know.
