Did/Do you have any antivirus(es) before and/or alongside avast?
No, the only security software i have is comodo firewall, malware bytes (on demand), Spybot (on demand), sandboxie
the strange thing is, it fixed by itself.. no more trouble for now ( 0,2 cpu usage and 30mb running memory) will confirm couple more days for sure
3. Why is there no option to really disable sending my computer information & files to avast server if a virus is detected? i know there is an option to do this if a virus is detected, but this is only work for that file. and i need to keep uncheck the box every time a virus is detected.
You may disable it by:
Choice 1: Deselect Participate in the avast! community during installation.
Choice 2: Double click avast! 5 tray icon > Settings > Community > Uncheck Participate in the avast! community > OK
unchecked, hopefully it will not send anything anymore to avast
thanks
