I downloaded the free Avast antivirus installer from the official website. After a while, the installer closed without warning. As I have seen, the installation was completed but, it seemed strange, so I reopened the installer and at 80% of the installation my computer crashed and I had to press the power button for 5 seconds. Then I restarted it and after 1 hour it crashed again. I ran this process about 2 times. Now, which should be the third time, a “shortcut” icon has appeared on my computer with “Avast Antivirus Free” written on it. Before I could not open the program, I could only run the installer but now, as I noticed, I can also run the program only which closes immediately. How do I fix this?
