achoo!

I think my computer has a virus. It's not loading right and it's pissing me off. It will turn on, and then it goes to some weird screen I've never seen before that says Microsoft Windows XP, and then under that it says Please Wait... and it just keeps adding '.'s. One every second and a half. Filling up the entire page with '.'s It wont let me do anything. I have no idea what I'm going to do.
The ironic part is that I just renewed my antivirus protection software. According to them I'll be protected from threats for the next 363 days. protected my-. Now I don't know what to do. I've never gotten a virus before.. assuming this is indeed a virus to begin with. I'm so frustrated. Grrr.
To all of you who have ordered some pictures fromme, hold tight. I need to straighten this out first. :) I'll keep you posted. If anybody has any adivice, HELP.
