when i turn my computer on i get this message "Failed to read firewall configuration"
and my antivirus "EST Smart Security 4.2" is turned on but when i try to start a scan it says "failed to run a scan" in addition that i can't update it, i use now Kaspersky virus removal tool, it takes too long to complete a full scan last time it took over 16 hours and i got nothing, it didn't tell me if i have a virus or not, my CPU usage is over normal and when i open the taskman to see the opened applications i see only the applications i use so i dunno what should i do, my computer is so heavy and i really need to use it, i'm on the final exams period,
thanks really for help
