I just loaded up AIDA64 Extreme 6.88 and it alerted me to an available update. I clicked okay to open the website where they have 6.90. I clicked download from Techpowerup, selected the .zip archive version, picked a US server and downloaded. I found nothing in my download folder. Strange... I downloaded again. This time I had a 0kb download and message from Windows Defender. See image.
I tried again downloading from official site "download.aida64.com (EU)" instead of Techpowerup and I'm still getting the same result - blocked and quarantined. Windows 11 and I already checked windows update and downloaded the latest security "intelligence" update prior to the last attempt to download.
