I don't know what to do next. I can't x out of the browser or close it via Task Manager.
I was just using Microsoft edge and received an error msg that said "you may have suspicious activity on your pc. Contact tech pc support for help 855-286-5016. Do not shut down or restart. Doing that may lead to data loss." It identified my IP address and computer IDa and mentioned Microsoft Edge. Is this legitimate or a scam? I tried looking up the phone # but it just says that it's private. Help!!
