I recently upgraded to windows 8 after a series of problems I had with windows 7, which started when I uninstalled Kaspersky Internet Secuirty 2012 to upgrade to KIS 2014.
After the upgrade, most of the USB devices I connected were not recognized (luckily the wired mouse and keyboard did keep working). Quite a few people experienced this and there's some registry voodoo to fix this. Unfortunately the fix didn't work, and since I had to reinstall windows to fix this, I decided to upgrade to win 8.1.
After I installed Win8 I had yet another 2 issues. The first one with VMWare Workstation. For some reason, VMWS wasn't able to create a bridged connection (most of my VMs use this rather than NAT)... going through the Kaspersky Forums, a few people recommended in this case to uninstall KIS, create the network bridge, reinstall KIS. What a PITA, but it did work.
So now I have everything ready to start coding? Not really. Some encrypted connections kept dying on me (something as simple as a git pull from a tiny github repo would take 10 minutes and end up in a connection failure). Pausing the protection didn't help, so I went through the pain of uninstalling KIS, trying, reinstalling KIS just to prove that the problem was KIS (rather than a dodgy router). Finally I found that KIS 2015 has a feature to snoop on all encrypted connections and that was affecting the connection. So I had to go to settings -> additional -> Network -> uncheck Scan encrypted connections.
I'm quite sure that companies providing security suites are having more and more trouble to provide working, compatible software, as malware becomes more advanced, the number of consumer applications multiply, and the incompatibility matrix becomes a 1000000000x1000000000 minesweeper game with half of the cells with bombs which move around.
I think at some point I'm going to install Sophos UTM and see how that goes...
