FRST logs looks clean, but you have two AV programs installed (Avast and Fortinet). Uninstall one of them.
Thank you veru much!
Fortinet I installed on the computer is not anti-virus software. It is a type of virtual private network, it is used when I open an application on the net, serving the education industry. I only use one antivirus software, Avast.
Ah, Have you seen the mbam.txt file for me? Last time (May 1, 2020), I scanned with Malwarebytes without setting “enable” Scan for rootkits ".
The next time (scanning for May 2, 2020) I set “Scan for rootkits” to be enabled before scanning.
Does it matter?
