I was testing the antivirus beta version this morning & it froze my internet a couple of times then was stable so I decided to test on Eicar site It allowed me to not only download zip files but didn’t detect Eicar when opened & executed. The only warning I got was when opening Eicar normal file & this warning was just from the Hipp asking allow or block. Windows defender detects these files every time before any other programme does. Avast detects as a Eicar virus test & ask to repair or delete never to allow.
This appears to be a problem with CAVS2 - if you right click the eicar file and scan with CAVS it will detect the test file but on-access scanner does not pick it up. The on-access scanner works well on real malware, it has picked a few up on various pc’s I have tested it on but it does not pick up Eicar files. Hopefully this will be fixed in the next CAVS version as it has been reported many times.
