I tried to download a screensaver from the link below, it worked I got the SS but I've been having unusual problems. First the command prompt now opens about 6 times then closes instantly on start up. I was afraid it might be accessing my computer so deleted all the files associated with the download and ran my Norton 360 which said it was fine when I downloaded it. Now the problem doesn't happen but I'm still cautious of it. help.

immediately remove SS from system,

scan system with Antivirus in safe mode.

enable windows firewall.
