**update**
I was able to get rid of it all together using Sophos Antivirus (which was an EXTREMELY aggressive antivirus).
Apparently the virus had only been out since the 15th of this month (no clue how I managed to catch it so fast), but that would likely make sense as to why it was so hard to find.
The script error continued popping up on restart, until I checked msconfig and noticed "windows script host" was set to startup with the command to run the script that was popping up.
I simply unchecked the box and all has been running beautifully ever since.
Thank you all for the assistance and advice on the matter, very helpful as always.
