if i just unplug internet cord then does it stop the virus?
also...how does one get a virus like this??
Viruses just want to wreck havoc on your Operating System. A virus can alter files or folders, delete important configuration settings, or even leave your system unable to bootup, Yes, viruses can be nasty, but they can't retransmit data from your PC to an attacker.
Are you currently running an Anti-virus? Do you keep your web browser (Google Chrome) up to date?
P.S. - When people suggest Malwarebytes, it's a great and productive program, but it doesn't offer real-time protection. They're malware scanning tools to scan once when you instruct it to. Unless you upgrade to the Professional version.
