Webfilter blocks AV Update eventough URL Group for domain is allowed

Question

Guys, can anybody help me? 
 I have a webfilter policy in place and it's obviously preventing my Desktop AV to update virus definitions. The webfilter looks like this: 
 
 At the very top I have placed an URL Group called AV Updates which is set to "allowed". 
 The URL Group containes the URL, where my Desktop shoul download AV updates: avira-update.com:

But the AV update get's blocked, I can see it "live" when enfording the AV to update new visrus signatures:

I did the same for clamav.net (for another desktop in my LAN) and there I have no problems anymore.... 
 It's driving me nuts..! 
 Any help is highly appreciated!

Hi sachingurung 
 I also trie dthis before... didn't work. 
 
 Solution: 
 1. found that avira update site was allowed by webfilter (of course, it was allowed it the URL caterory group) 
 2. it was a *.cfg file that was blocked by application filter and I had to create an exception for this too 
 It's working now :) 
 
 But thank you for your feedback :)
