I believe I was scammed through a fraudulent webroot call. They accessed my PC through teamviewer and said that my network was comprimised and that there were people actively aswell as waiting to get on to my network wher they would be able to see any of my personal information. They then began to attempt to "clean my network" and "block the hackers", when they suddenly said that I would have to pay them for an SSL. They initially said it would be $300 dollars then they told my grandmother they could give her a senior citizens discount for a lifetime subscription for just $200 instead. This is when I believed it fully to be a scan and I disconnected from Team Viewer and hung up the phone. But at this point they have already gotten my grandmother to download things from there website and had access to command center where they type differen things in. I would like to know how can scan my network/PC to find out if they left anything malicious on the network or computer.
