My current top 5 is:
- McAfee Webadvisor
- Norton Safe web
- Malwarebytes
- Avira
- G data
(The sites I used are detected by a Palo Alto product).
Actually tried all of the above
From the 5 you mentioned
Macafee and Malwarebytes did best in my test
Anyway specifically G data I have only tested once as the results weren't good enough for me to keep testing it but I will retest myself
Btw it's awesome that you're using a good intelligence feed for the testing
Thing is macafee by default flags suspicious catagory and once I do the same in for example Symantec it gains more detections then macafee
But by default sometimes macafee catches more and sometimes Symantec anyway macafee is definitely a good extension
Btw if there is any free feeds you can recommend it will be awesome as a need better quality feeds
