I got scammed by someone from TechHelp. It's a male Indian and he did random things on my laptop screen. He also wanted to webcam me.
You got scammed by some sleazy Indian criminal. Who knows what he actually wanted.
As the others have said, get you machine checked over by a trusted local PC tech, and consider backing up your data and reformatting it to be 100% certain there is no malware installed on it any more.
Format the hard drive and start from scratch. That's the only way to be sure you've removed all traces of these villainous scum.
I would run as many virus / malware scans as you can and I would consider backing up any important data you have and reformating the computer.
Not smart. Take it to a professional and have it cleaned. No telling what they did with it.
