Files download by themselves?Need help desparatly.

[drayvin04]

OK, last night I created a new folder to transfer downloaded songs to, and when I got home from work this afternoon, there were several porn clips downloaded in the folder. The only one that was here was my 13 year old sister, and she swears to God that she did not do it, but I don't see how they just automatically downloaded by themselves. I checked the properties on the clips, and they said they were created about an hour and a half ago.Can anyone here help me? Is she full of crap, or has this happened to anyone else?

Sounds like you have an active Trojan or virus on your PC probably planted to give some miscreant access to your machine. By the way, do you have any protective apps on your PC?

[drayvin04]

and there are no viruses on the computer. What do you mean by protective apps?

I think it might be your sister. I never heard of a virus downloading from limewire.

Just to make sure that it is really not an intruder:

http://www.ewido.com(free trial which can still be used and updated after the period has ended -the best in my opinion)
