I don't hate FireFox but use IE or else...

I kept receiving the above message every time I tried to open the FireFox browser in my office. I don't like to use IE before it is so slow. Tried the virus scan but the same thing happened again. During lunch I told hubby about it. He experienced the same at his Internet cafe. It is a virus. He told me that one way to get it of it by doing System Restore. It can be found under System Tools in your Accessories. Since I did not save anything important in that computer, I run the program. It works! I can use my FireFox again! :)
