<human>: Can you succinctly summarize the text in 1-3 sentences?

So, if you're a gamer and into modding, i'm sure you've figured out by now that not all mods are safe but the majority usually are. But modding a game that was made near the dawn of the internet is really fucking risky. And as you can imagine I tried this out from a trusted modding site I use quite frequently. I figured that if it was malware, MalwareBytes would do its job and remove it before it did anything, this was not the case. I downloaded and installed the mod, and then BAM! Immediate slowdown. I didn't even get a notification saying "malware detected". So I ran a scan and turns out I had Malware AND another form of Virus and both MWB and Avast did not detect them so I disconnected from the internet and shut down my pc and then took the HDD out from the case for good measure. I did some googling and found out that apparently a shit ton of old viruses arent blocked by modern antiviruses, nor can they be removed by them. So for the past 2 and a half hours i've been going through every directory and reg manually deleting anything associated with this virus. I also had to search through all tasks and shut everything down that wasn't keeping the system going.

Never again will i attempt to install mods for games that old. Never.
<bot>: Installed a mod and my Antivirus didnt pick it up that it contained malware, got a virus and spent the past 2 and a half hours removing it. Penises everywhere
