Relly don't want to have to setup a 2nd computer just to download updates.
Mostly i tend to just use street smarts when it comes to social engineering attacks.
Now i wouldn't expect the avira update downloader tool to do anything evil or harm my pc but it seems to me that when it comes to computer anything of late its a free for all when it comes to privacy invasion and that's basically why when i see a app like that from anyone i don't like em in general.
My self with my computer setup i do everything i can to not be part of the privacy rape party that seems to be going on and i have no facts, no prof of anything on the Avira downloader tool and im not claiming anything other then just having a gut feeling about the topic, knee jerk reaction is that they are using it for data mining.
I could just for fun sand box it with some software or guess and run wire-shark at the same time and see what happens but even if i did find anything i have a feeling i know what the joke is and "B" i dont really want to hurt Avira publicly, sadly when it comes to anti-virus of late the amount of em out their that dont flip if you dont have a internet connection and want to spy on end users or are cloud based and want internet connections "meaning can be used on computers with no internet" is getting harder and harder to find.
prof i have that its spyware = none but the fact of the matter is why would you ever do it this way for any software or updates vs FTP server or just download site combo if it wasn't to have a helper on the inside to scan the pc before download and send that info to home base or in some cases iv seen from 3rd party downloader apps on the net they try and install crap + spy on your box the min you run their downloader.
Sadly even if your pro with fire-shark its really hard to know anything with it even with a full capture seeing as chances are everything encrypted.
Use to have a app "most it was for hacking other apps" that could sand box something and everything it did you'd get a print out of it, forget what it was called.
Min the Avira update downloader should come with a legal agreement/privacy agreement but doesn't
