Hello,
This morning my PC has been infected by a trojan named SupportScam:JS/TechBrolo.F. Windows Defender has detected this threat however Avast did not. In fact, Windows Defender said that "C:\Windows\Temp\_avast_\nsfsp00001943.tmp" has been affected by this threat. Moreover, each time I start my computer, the agent suspicious actions is disabled and each time I make a smart scan, my computer crashes and I have to restart it. According to Windows Defender, this threat has been eliminated but my computer is extremely slower now. So what should I do ? Should I re-install Avast ?
