Was using F-Secure Total (short: FS), which out of sudden repeatedly
did not receive database updates (it somewhen did again, with the latest), which seems a global issue (another report
here, more on Google), and the VPN was getting slower, rendering my internet connection useless for casual surfing. However, the biggest issue and the reason to abandon it for me was the transition to Avira and maybe the drop of DeepGuard - which is the most important module for me, as stated in the BETA thread
here.
As I was previously testing K7 in the HUB, and had it installed on my old machine anyway; I equipped my two laptops as well as my main tower with it after upgrading to Win11 24H2. After clean install, the performance of K7 is absolutley awesome (it is the Infiniti version I purchased a year or more ago, it might use MAT now, too). Plus it feels like install and forget - it autoupdates every hour, and installs new version without notification (seldom in the past, it required a reboot, you will get to know about).
I'm aware that K7 might not be on the level of main AVs, however I feel quite confident with the maxed out settings, Evorim Firewall (which accompanied FS too, and did intercept outbounds FS did miss in testing, too, mainly scriptors, weakness of both K7 and FS). Edge is also configured to non-intrusive but high security, and comes with AdGuard and Bitdefender TrafficLight. Only thing I might be missing is FS Banking Protection. Against ransomware, my machines also enjoy AppCheck AntiRansomware free, however K7s DataLocker is pretty aggressive on processes it does not know, the SmartAnalysis does not work well, you will have to add exclusions for e.g. SoftMaker Office and Edge (if you protect the Download folder) on first run.
EDIT: I'm also using Windscribe VPN, which promises to have both a Firewall as well as R.O.B.E.R.T. (a DNS filter against malware and ads).
