I was searching through my documents folders and found a file named julia-cutecandy that was an MS-DOS application and 20kb big. I clicked it and it opened a DOS app, then immediately said it had performed an illegal operation and closed. Could this have been a virus? I deleted the file.

It was in a folder that I use for pictures, but occasionally I may download something and randomly place it in a folder for use. Could it have just been an unrecognizeable picture/app?

Hi there & welcome to PC Help Forum.

Do you have an anti-virus program installed and running and is it up to date?

Yes, my computer is very-well protected.

To quote Joe that helped me in the past.

"Looks like youre pc is good protected , you have an firewall , AV , malware protection , and windows seems to be updated. So i doubt that that site could infect youre pc.

Then I was just freaking out over nothing. I hope I am now, too. Sorry for wasting your time if I am, but also thanks for taking the time to go over this with me.

Hah, you're not wasting our time

Best to be sure tho' - just download the latest update for your AV and run a full system scan

Will do. Thanks, mate.

Just, ugh, I've had so many problems with computers in the past that any minor possible breech of it freaks me out. X_x
