As per my experience (described above), it does not seem to be ‘permanent’ problem with this new 21.2 version but rather silently failed upgrade from 21.1 version. I upgraded from 21.1 to 21.2, experenced this issue, so uninstalled 21.2, then installed 21,2 again as ‘fresh’ installation (not upgrade from 21.1) and this problem went away.

Then what was the problem ? Disabling entire protection or just network module helped as a workaround. Reinstalling KIS completely resolved it for good. I see no other possible fault than KIS itself. Probably fault was not in the network filter driver.

Support advice wasn’t very helpful - they asked to uninstall some ‘suspected’ programs - such as ASUS AI Suite III (doh...) or Primo (I’m assuming they meant Romex PrimoCache here) plus two more with generic names such as ‘Runtime’ or ‘Downloader’ so I do not even know what it is and how to uninstall it. Of course I was using these programs long before upgrading to latest KIS version, with no issues so I wouldn’t suspect them. I’m glad they haven’t asked to reinstall Windows ;-) You guys having the same problem - have you reached 21.2.16.590 by upgrading from previous version, like me ? My guess is that upgrade itself is the problem, something must have gone wrong on the way. I uninstalled KIS 21.2.16.590 completely (with option to keep KIS settings unchecked, I just asked to leave license/activation data in place) and then installed KIS 21.2.16.590 afresh. Issue gone ! Try this and let me know if that helped you...

Hi, I tried it just now - still the same problem. I’m trying to download 8GB Linux ISO file and there’s no chance of downloading more than around 300MB’s - all download attempts hang somewhere before 300MB mark. When I want to revert this change, what should be start type for this service, system or auto ?

Hi, Disabling “anti network attack” module does not help, it’s still the same problem. Also disabling Kaspersky Protection extension in browsers does not help. Three browsers are affected (Chrome, “new” Edge, Firefox). I have not tried IE. Downloads ‘out of browser scope’ are not affected - such as games from Steam, nVidia drivers from nVidia GeForce Experience etc. etc. Only disabling WWW protection module (or entire Kaspersky protection) does help. Thanks

I’m having EXACTLY same problem since upgrading to 21.2.16.590. 21.1.15.500 worked fine. With smaller downloads (say up to 100-200MB) it’s not a problem - you can retry download at worst case and it will complete. Bul larger files will never complete, they randomly stop and hang at various percents and there’s no way to resume. You need to start over again and then it will hang at another point and so on. Either web antivirus module or entire Kaspersky protection must be disabled for downloads to be successfull. I also opened ticket INC000012194577. Zbyszek
