Hello,

Out of curiosity I downloaded various Eicar files from here:

https://ipinfo.info/html/testvirus.php

I was able to save most of them in a folder, without any reaction from Webroot.

If I scan the folder , the are detected as “malicious” , but no reaction when I downloaded them.

I have “Scan archived files” and “ Check files for threats when written or modified” selected.

Theoretically , these Eicar versions should have been scanned upon download.

HTH,

As you can see , when unzip they are detected , so the theory about “they are not detected because WSA knows there harmless” does not hold water.

 

They should be detected upon download, before being stored on the PC, not after they are stored and purposely scanned.

 

“You should go here: https://www.eicar.org/

 

This is not a detection, this is a “reaction” implemented in each and every antivirus.

 

As you can see, downloading Eicar from a different location doe not trigger any reaction on Webroot.
