new users on my windows 7 was created named fbwuser and I did not make it
accounts names is :
1-fbwuserF45B
2- fbwuserF45B
3-fbwuserF45B
4-HomeGroupUser$
i have heard that may caused by hotspot or any VPNs program
any idea !!!
see instructions here https://forum.avast.com/index.php?topic=53253.0
scoll down to second picture … Farbar Recovery Scan Tool … run as instucted and attach the two diagnostic logs
see below the box you write in … Attachments and other options
Logs will be checked by an expert tomorrow
Sounds like it is something (vpn) from anchorfree
here is scan logs and seems fine
Those users are disabled… Did you set this proxy
ProxyServer: [S-1-5-21-2427239002-3345539292-2558161799-1006] => http=127.0.0.1:8555;https=127.0.0.1:8555

NO I DIDN’T SET ANY PROXY MANUALLY
but i use vpn add-in with Firefox called ““browsec””
add-in website : https://browsec.com/en/
It may be related to that, you can test it out by uninstalling the VPN and see if the proxy disappears
uninstalled , restart , scan and u r correct
