Avast premier 11.2 - Alexa.com False positive

Avast Free Antivirus / Premium Security
1

I just started using a trial version of Avast premier 11.2.2261, when i downloaded website report of malwr.com from Alexa, Avast blocks the download saying it blocked a virus(PHP:BackDoor-FN[Trj] ) !!

How is this possible ? First of all the downloaded file is an archive report file and there is no way it can contain a virus because they are generated when you make a request , how come it blocks an archive file of Malwr.com and no other websites?

Is Avast getting confused with the file name or names inside the archive ?

I was a eset nod32 user, after upgrading to eset nod32 antivirus 9 , it began to affect my system performance and finally i removed it and installed Avast premier. I really liked the product with low system impact and fast scans but these false positives put me in a place where i need to rethink buying the premier version and i need to say that i didn’t have any single false positive with eset nod32.

I need help from users, below is the screenshot of the alert i got.

Thank you in advance

Malwr.com is a place to upload analyse and share malware samples

Does the report you try to download containe a php script? … or the download url

Do not panic!
Sometimes these examples/samples without payload of course could show a tiny bit too much of the real code to cause an Avast alert
as if it was the real McCoy.
Nothing to worry about but a detection tool sometimes cannot make the distinction and the alarm bells will start to ring.
Now you know what happened, you have nothing to worry about.
