Avast won't open

Hi, I’m an Avast Free Antivirus user on Windows 10 64-bit. When I open Avast it closes itself after 1 or 2 seconds with no apparent reason. I’ve already submitted a ticket on Avast official website, but it’s been more than an hour and no one has answered me yet. Can you please help me? I don’t know what to do, I’ve already restarted my PC a couple times now… Thanks for the attention, and I apologize if this is the wrong section… I’m new to the forum

Please try the following:

Repair Avast:
Control Panel> Program and Features (Add/remove program)>Select Avast> Select Repair. Reboot when completed

If Repair doesn’t fix the problem, try the following:
Clean Install of Avast:

Thank you! Solved!

Glad to hear that. Thanks for reporting back. :slight_smile:
