It is advised to take all reviews with a grain of salt. In extreme cases some reviews use dramatization for entertainment purposes.

I recall having F-Prot DOS running on its own DOS pc and putting newly obtained file on floppy and scanning it in DOS before running it on your windows.
Exactly, it was the first version I used. I told @Sorrento, but I don't know if he saw my post or if he was already leaving. It used a floppy disk with an interface very similar to Norton Commander, if I remember correctly. Thanks for reminding me. Well, folks, I have to go now. Good night, good morning, or good afternoon, @simmerskool. I already said goodbye to the others. 🖐Now I'm off rest. :sleep:
 
@Trident You're right, look at the number of users and installations of McAfee WebAdvisor. I've never seen an extension with such high numbers; it's very popular. Someone correct me if I'm wrong, but is 101,000,000 users in the millions or billions? That's a lot. Now I'm really gone, this is endless. (y) Best regards to all. ;)

Norton many years (25 maybe less) ago totally lost their way totally with updates to the updater that was broken beyond repair & it became such a mess I vowed never to use it again,
Fairly often they would make some changes to how definition updates were delivered and when they happened, it would no longer receive updates. Not only would you no longer receive updates, you wouldn't get any notifications indicating that updates had failed. In a week or two, Windows would alert you that Norton had out of date signatures. The solution to this would to be run Live Update and it would download and install some product updates that would fix the signature update issue for the time being. These updates would only be installed if you manually ran Live Update, as Norton would only automatically check for and download new signatures, not product updates.
I don’t agree. The old Norton was a dream. It was snappy, the UI was a testament and a reference. It did the job. Alerts and everything was nice and compact. Anyway, no point drooling over the past. Norton is gone.
Many years ago Norton was often extremely heavy, making computers run very slowly. I remember doing a fresh install of Windows 7 on on friend's computer after replacing a failed hard drive and then installing the latest version of Norton 360. It made the computer, which had pretty powerful CPU, run very slowly, so I uninstalled it and replaced it with the free version of Avast, which ran much better. But around twelve years ago, they make it a lot lighter and it went on to became one of the lightest antiviruses.
 
Due to the time it takes for every test, I can only perform short tests, but I try make them as meaningful as possible.

So basically McAfee is now one of the most solid ones out there?
