Can anyone tell me a good security suite for win 8.1?

Hi:

I am looking for a good security suite or a an av plus firewall that works good with win 8.1. I have read the latest CIS may have issues with 8.1 at their forum. Also I am not sure about AVASt and if the new version is 8.1 ready and issue free. ANyway here is a list of avs that I like and can anyone tell me if any of them is 8.1 ready and 64bit ready and works well with sandboxie (compatible) and safe? My system is windows 8.1 wmc pro 64bit.

AVAST
CIS
Ashampoo AV 2014
360 IS
Baidu AV
online armor
new rising firewall
Bitdefender av free
zonealarm plus av free
Ad-aware free or standard
unthreat
or any other.

Thanks in advance.

 

Using F-Secure, and I love it. Runs quick, barely know it's there, and it does its job quietly.

8.1 x64

 

Thanks for reply, but I am looking for a FREE av.

 

But you might find that the F-Secure Online Safety add-on is not yet fully compatible with IE 11. They are working on an update for this

 

Well in that case, Ashampoo in your list is not one of the free ones.

 

Yes but I have 6 months license of it. Anyway I tried ashampoo av 2014 and new rising firewall v. 24 and they are comnpatible. Although ashampoo browser detection is reduced in sandboxed browser but is solid in non sandboxie browser.

Thanks for your replies.
