Oh geeeeezzzzz,
People are such wimps about "VIRUSES". If you have worry and doubt, which far too many do...create a restore point prior to installing the possibly malicious world-ending virus. If it F's with your system in any way, simply open system restore and rewind time! Real easy.
Not sure if anything was messed with? Check to see if any new processes are running in Task Manager, if yes... KILL THEM. Another way to check for any harmful additions is open your C:windows\system32 folder and sort files by date. If you find a brand new file in THAT folder, which was created at the SAME time you installed your questionable.exe... KILL IT. Or at the very least investigate it.
And to the author...Im pretty sure the only reason you created this script and posted it here, was to have an excuse to show off that meticulously designed & organized desktop of yours!!
