I had Avira Free Antivirus for a year now and it was working fine until now.
Avira is still on as far as i know. Real-Time protection also works, although with slight differences. I tried doing an EICAR virus test to verify this. Instead of Avira giving me a pop-up about a detection, Avira didn't. However, I wasn't able to open the EICAR text file anymore, so I assumed that Avira was blocking it. The problem is with the scanner. Whenever I start a system scan, the scanner opens and runs for a while, although it's not scanning. I can pause the scan and resume it fine as long as the scanning process hasn't started yet. But before it actually starts scanning, the Scanner just crashes. I did this a few times with the same result. I'm not sure when this started since most of the time, I just let Avira do a regular scan and I never tried manually starting a scan.
My PC is an ASUS Model X555L running Windows 8.1, in case it's needed.
Thank you for helping.
