Just got a call from this number. I actually work in IT so I knew right away it was bs, so I toyed with the guy for a while, then called him out.
him: "so yes, we are seeing malware and viruses on your computer"
me: "oh really? What's the IP of the computer?"
him: "it is a temporary IP of 192.168.1.125"
me: "yeah, no.. that's a local IP address lmao. Obvious scam."
him: "it's not a scam or I would be asking for credit card information, we just need you to visit a website so we can remove the malware"
me: "you mean hijack my PC and then demand a ransom to unlock it. Get a real job."
