The computer shut down while playing FiveM.

[Chewbaca08]

Good evening, five minutes ago I was about to log into FiveM with friends. As soon as I connected to the server, Kaspersky gave a warning that it was cleaning. I pressed Alt Tab and tried to access Task Manager, but it was giving an alert saying securityhealthsystray. When I shut down the computer and turned it back on, FiveM Discord was gone. The desktop background had also changed. What should I do?
