I am worrying that Avast will still do nothing when it is a real virus.

What operating system do you have - 32bit or 64bit?
The link posted goes direct to the eicar.com file so it will be blocked by webshield
The main Eicar page can be accessed but the minute you try to download any of the files you get blocked as is to be expected

Mine is 64bit.
When I have turned off ‘Block malware URLs’ in ‘Web Shield’, ‘File System Shield’ will do nothing to block ‘eicar.com’, which can thus be downloaded, saved and run.
Is it acceptable?

after you have saved it … if you right click on it and scan, what happens then?

i think that is correct as it is just a txt string, i dont think .com file (MS-DOS) run on Win10
will see when Igor is back with a reply

Yes, Eicar isn’t detected “on execution” (i.e. when you doubleclick on it) on 64bit operating systems because it’s a DOS COM file and there isn’t any 16bit subsystem on 64bit Windows that would be able to execute it. So there is no execution being started, Avast isn’t called to scan the file and the file isn’t detected (Windows just gives you an error that the file cannot be started).
That’s as expected and it’s nothing to worry about. It would be detected on 32bit operating systems (because it can be started there), and it doesn’t mean that Avast isn’t scanning for viruses (those that actually can be started).
Well now works on https eicar as always, he was wrong not perhaps some correcion of virus databases. ;D ;D ;D

Is there a test virus that can run on 64-bit Windows, which is becoming common nowadays?

What if Eicar.com is run in dosbox on a 64bit Windows?

You’re the curious one so why don’t you try it.
I think this topic has beaten itself to death. Time to end it.
All the questions on something that only required one answer have already been answered.

bob3160 is using 64-bit Windows, and his File System Shield blocks eicar.com.
I am also using 64-bit Windows, but my File System Shield does not block eicar.com.
Why?

Because… I was posting at 12:26:37 AM 
Now I’ve just tried, and Avast did not detect Eicar.com execution in Dosbox on my 64bit Windows.
I guess such behavior is expected, is that right Igor?
EDIT:
After a while I’ve noticed “Virus Found … Process PID 4292”, see screenshot below.
Perhaps, Avast does not detect execution but it detects the Dosbox process using the file anyway.
And, Avast DOES detect eicar.com when I download it.
Bob, I don’t care about Eicar.com as such, but I am curious because I have some old DOS and WIN 16bit programs which I might execute in virtual boxes sometimes.

The blocking on Bob’s machine was caused by the file being written to / created - that works. Just the execution doesn’t as the file cannot actually be started.
