Hi mmabdallah,

If supported on your operating system, try a boot time scan with avast! Right click the scanner screen, select ‘schedule a boot time scan’ and reboot when requested. (Or open the tab at the top left of the scanner screen and select the boot time option from there.)

thanks for ur support…but if u know something else need to be changed i will be glad
