I think K7 finally deserves a sub-section on this forum.

Very recently I had the chance to test it. I just can't believe how light this AV is! On idle, RAM usage is <45MB and I feel no effect of system performance being dragged down, in fact it is faster!

  • In Performance Test at AV-Comparatives, the impact score it received was 0.8! and was the lightest antivirus tested, much lighter than ESET.
  • In Real world Protection Test at AV-Comparatives, it scored a perfect 100% with 5 false positives.
  • In Malware Protection Test at AV-Comparatives, it scored a 99.99% with 1 compromised
  • A cause of concern is the number of false positives where it detected 47 clean files in False Alarm Test at AV-Comparatives, I could live with it.
  • At AV-Test it scored 5.5, 6, 5.5 for Protection, Performance and Usability
I believe this antivirus has come a long way, and probably work on it's flaws to be a top notch program.

This is very true. K7 is the lightest AV I ever used. Even faster that ESET and unlike products like Mcafee and Emsisoft who scans on execution only to make things faster. K7 is insanely snappy.

Agree, super light AV, decent signatures (at least for .exe, not so for scriptors and office files).
BB is also very reactive, seems to not rely on the cloud like many other products (works offline, too).
Lacking in terms of Ransomware Protection though (it does have DataLocker though, which prevents file encryption for covered folders - by default documents, pictures - by 98%, during my testing in the HUB, in very rare cases RW bypassed folder protection).
And sometimes HIPS does not recognize new AutoRuns (for example by scriptors), it did sometimes remove them after 20-30 minutes, not that stable yet.
But in most cases, you should be safe, even more as usually malware does not tend to pop up in bunches on the local machine like in the HUB tests, but rather takes the way via the browser, where K7 Web protection shines (at least for malware links).

EDIT: I really dislike there seems to be no option to ask for outbound by trusted M$ processes, even in highest settings (apart from block everything), they're whitelisted on outbound attempt.
Better create your own list for (later hollowed) Windows .exe you don't want to see call outbound.
All other services are ask first as intended (if you change firewall behaviour to do so, by default it doesn't).

1.jpg2.jpg3.jpg4.jpg5.jpg6.jpg7.jpg8.jpg9.jpg10.jpg
All tickets created so far. I marked all tickets with RW bypass in the subject, could be even more.
eMail:
Enable Worm Blocking, Scan outgoing eMails
Scanner:
also Scan Memory, Tracking Cookies, Unwanted Registry Entries, Unwanted Files
System Monitor:
Custom Level of Protection (actually all boxes are activated by default or because of "High" setting used before)
Always Prompt if a new Software is installed when changes are found
Do not automatically allow signed files / recognized by the System Monitor
Firewall:
Display critical alerts
Ask for outbound connections of non-whitelisted apps
Intrusion Rules: Activate also SMB Exploit Detection 1, HTTP Server Exploit Detection 1 and FTP Server Exploit Detection 1

Data Locker (custom setting not applied in previous tests):
Do not use SmartAnalysis to discover Trusted Applications
Trusted by Data Locker before setting turned off:
C:\Windows\system32\BackgroundTaskHost.exe
C:\Windows\system32\BackgroundTaskHost.exe
C:\Windows\system32\RuntimeBroker.exe
C:\Windows\system32\PickerHost.exe (=Snipping Tool to create screenshots)
C:\Windows\explorer.exe
C:\ProgramFiles\SoftMaker Office 2018\TextMaker.exe
C:\ProgramFiles\SoftMaker Office 2018\PlanMaker.exe
C:\ProgramFiles\SoftMaker Office 2018\Presentations.exe

Data Locker by default protects Pictures and Documents against writing performances by processes not whitelisted as above.

Thanks for the explanation Dr.Reisende. I haven't seen K7 web protection in action. Does it not work on Vivaldi? Couldn't find an extension for the web filter too for it. I tried opening some phishing links, an even though it doesn't get loaded, I don't see any banners from K7 (showing webpage blocked) unlike ESET does.

What am i doing wrong?

Not about Chromium based Browsers (i use Brave), but definitely works in IE.
Does not need a extension (even it tries installing in Brave, but does not activate as no current version is found in the Chrome Web Store).
Check on VM / in SD with URLHaus links maybe?
I haven‘t K7 installed on my laptop anymore, but at the PC which is located in my mums home.
Will take some days till I be there again.

I also have the feeling K7 is less decent against phishing links, tried some last time, none blocked, however I cannot tell whether all were legit, Phishtank has also FP.

Web protection is ok against MAL URLs.
But lacks a lot in phishing but certainly better than
Dr WEB.
I also have feeling that BB and signatures against non P.E, scripts, macros is not good .
Firewall is not as adv n automated ,in fact poor as compared to Symantec n Kaspersky.
 
4 bucks is friggin inexpensive. i see they have a demand scanner i can play with :) it says:

K7 Disinfector Tool
Generically detects and cleans a subset
of prevalent file infector malware that
infect files on the computer.

I think K7 finally deserves a sub-section on this forum.
And here we are, 2 months later, and still no sub-forum for K7 Computing... Or for AhnLab... Or for VirusBlokAda... or for eScan... All of them being large companies that have stood the test of time and constantly update their products.

How does one go about to ask the MalwareTips owner to add sub-forums?
