I have had the free version of Zemana (BC download) installed on my notebook for well over 18 months now which is set up to do a daily background scan and I haven't been infected since (as far as i know). Although the free version does not give real-time protection, it appears to work flawlessly in win10 and I wouldn't want to be without it for use as a safety net in case anything slips past Defender.
I looked free version does not cover safe web or anti-ransomware. they say they are the best at anti-ransomware but all I found is Kaspersky's solution works wonders. I think I'm gonna pass safe web function because uBlock Origin is proactively protecting at web.
After 3 days I will install anti-ransomware Kaspersky, anti-exploit Malwarebytes (this is also 0-day protection) and that's it. I also have Defender for main AV real-time and Malwarebytes free for scanning.
For network monitoring I want to try out GlassWire. Can I use it freely? I don't want to have firewall mechanism though because I have Windows Firewall active.
As far as I am aware, the only free program that offers decent and specific protection against ransomware is MWB AntiRansomware Beta version. I am sure there are other (and maybe better) paid-for AR suites available. I had Glasswire installed on my notebook for a while at a time when I was convinced my wireless was being hacked and although it's undoubtedly a neat program, I soon came to the conclusion I wasn't being hacked after all (it was PUP's that were slowing me down). When I used Glasswire it was free to use, but as in most cases with free security, there are usually more comprehensive and better-equipped versions available that you have to pay for.
I myself am a purely recreational rookie pc user. if the few files I have on my device were ever encrypted by ransomware, I'd simply wipe my drive and start over because I have everything I need backed up.
Personally, I think you can drive yourself nuts worrying about what security you need (or THINK you need!) to have installed on a device, as well as wondering if one scanner is better than another etc. I know I did! A good anti-exploit program, Win Defender/firewall and a daily automated Zemana scan is all I'll ever need myself as long as I keep using my pc the way I do. But everyone's needs are different because I can't imagine any 2 people globally will use their personal devices the same (browsing habits etc). There is no 'one size fits all' solution as far as computer security is concerned.
As far as scanners are concerned, all good ones now use a cloud database with all of them sharing one another's database of definitions to a large extent, so all of them, technically speaking, should be as good as one another....provided, of course, you update their definitions when prompted....and that the program itself is legit! (as in those available on Bleeping Computer).
As a novice pc user, I was convinced at one time that more was better as far as security was concerned, but now I have learnt to lighten up a bit and only use what is necessary for my own needs. This has come about all through trial-and-error as well as a little research on my part.
Personally, my own golden rules of safe computing NOW are as follows
1. Have just ONE good AV/firewall suite. Win Defender seems just fine.
2. MWB Anti-Exploit for protection against zero-day (yet-to-be-defined) malware. (Voodoo Shield looks interesting too for this).
3. Update definitions of scanners, AV, Windows, browsers regularly and/or when prompted, as well as all other programs you have installed (Secunia PSI comes in handy for this)
4. Use a good scanner DAILY, weekly at least. I certainly wouldn't wait a month between scanning.
5. Most important of all, back up everything essential.
That's basically it. For me, at least. But all our needs vary.
I haven't mentioned e-mail threats because I know little about them due to not using the facility much and never opening spam, but as I understand it to be, that is where most ransomware will originate from.
An interesting topic you started here and I hope you haven't minded me joining in the debate. As mentioned, I'm only a rookie pc user and my comments are in no way intended to serve as advice of any kind.
