Be very careful : is your anti-malware software giving you this message, or something else? Take note of the grammatical error : "Viruses was
found on your computer!!!"
I suspect this could be scare-ware trying to entice you to click something. I very strongly suggest doing the following:
1. Install and run a FULL scan with Malwarebytes
- post the resultant log here.
2. Do another scan using online ESET
Post back here if you need help, but don't
click anything on that pop-up message, just close it.
EDIT: Bil remind me to crush your fingers for being so much faster than mine
