Avira is not updating
(multiple engines, cloud only) it is designed as a companion AV and nil issues with Win10.
The shop said that that would update the anti-virus to the current version.
The best place to get assistance (after giving more detailed info) would be the dedicated Kaspersky thread: /forum-replies.cfm? What are your thoughts on free Firewall software such as Comodo or Zone Alarm?
Better, worse or equal to the Windows 7/8/10 firewall?
They have their own engine and were a damn good AV, dumped them for AVP (Kaspersky) when that came out.
Haven't seen it or heard much about them in recent times, might download a copy and have a look, it used to run lean and mean but as I said that was all a long time ago.
