Computer problem

[Great Rumbler]

Did you recently upgrade Quicktime?

No, it's been a while since I upgraded it.

then some sort of virus could have infected your machine, one that your virus checker didn't detect.

I'm running Norton Antivirus and it's only been a couple of week since I downloaded the latest virus definitions.

Now I must ask, are you the ONLY user of your computer? If you aren't, who wants to kick some arse until they find an answer as to who did what to your machine?

My little sister uses my computer and it's altogether possible she did something to mess it up, but I don't think asking her would do any good.
