While searching for virtualization back-up solutions for ESXi, I came accros the following website:

http://joealdeguer.com/backing-up-and-restoring-esxi-virtual-machines/index.php

 

 

But the proxy server that filters internet browsing, where I am at the moment, yelled a warning and blocked the page:

Squid_clam_URL_blocking_240313-copie-1.PNG

(Yes, the is a Squid proxy server powered, and antivirus engine is ClamAV).

 

As you can see, Clam says "PUA.Script.Packed-1.

 

Now, let's try VirusTotal for this same URL:

 

https://www.virustotal.com/en/url/9be98ad47adc382824285f27289bd20cc9f2b71ba1f5761a8c15ecb95b877a1b/analysis/1364141731/

 

Well... nothing found! even Clam...

And no, don't tell me it's because it's a PUA, and therefore it's not reported in the main view...!  The "additional information" tab says:

Here, OK the URL by itself is not categorized as "malicious", but at least one AV engine (Clam) should trigger a warning on VT, if it really matches the AV regular behavior.

 

In a nutshell, you may want to try VirusTotal for URL scan, but even if it does not give you any result, I do suggest you to manually download the content targetted by the URL, and then upload it to VirusTotal, to double check.

 

 

Small update:

 

if you download the webpage, save it as " web archive" in IE, and upload that to VT, here are the results:

Yes, there you see that Clam does detect a PUA (additional information tab).
