When I got my imac and used it for a while, for some reason I get .exe, .rm, .mov, and some other files on my desktop, and their filenames are like dhdhdhdhdhd or sjakdshlj34338 and stuff, and when I open them, they are some of my other files I already have, but they appear for no reason. What causes this and how can I prevent this from happening. I know they are viruses because they loaded just fine.
anything that can help is great.
