Received an .avi clip (I know, I know), I didn't open it until after a v-scan. When showed ok, I viewed it and immediately, it started using up all my system resources through explorer.exe. It tied itself there and then sysmon.exe began attempting to access the internet. As soon as I block it, it tries again (over and over and over again). When I shut down explorer and reboot, it stops and is not a problem again. Big problem is now the file is 28GB (That's right GIGABYTES!). I tried erasing the file. This starts it going again. I tried deleting it. This starts it going again. I tried deleting it from the command prompt. Can't find the file (Invisible?). Can't rename it or move it. HELP!!!!
