Ok, I reply all the posts here rather than individually but not in sequence just the points
First of all let me say something - DON'T FOLLOW WHAT I'M DOING!!
Backup work files and system
I mentioned before I'm only backing my my work files by copy and paste onto a flash thumb drive daily. And I also have all the program installers copied to the flash drive as well. As for any system back up and rollback I don't require it. I rather let my system screws up and then reformat and re-install my programs. I have done it quite a number of times and I'll continue doing it. The reason being some times it's good to give the system an entire clean over. I can then re-think of what software are needed to be installed and what's to be discarded.
Password Manager
I don't have 500 passwords to keep. I also mentioned that I keep my passwords on a MS Word file and this is also copied to my flash thumb drive with those aforementioned files. FYI, I'm the only one using my MS SP3 so I have no worry of theft of data or important items being stolen for I'm keeping my data files separate from my MS SP3.
Registry Cleaners
If I'm not wrong CCleaner and Wise Registry Cleaner are the safest of the registry cleaners from internet reviews and that's why I'm using them. Most of thh times I'm using the Quick Clean method. They have not given me issues till to-date.
Avast AV, ZAL and HMPA
Avast AV is my main AV and ZAL is my main AM. In HMPA I've disabled its KB encryption to avoid having conflict with ZAL.
BitDefender TrafficLight (BDTL), Avira Browser Safety (ABS) & uBlock Origin
Frankly, BDTL performs actively in Firefox whilst ABS works actively in Chrome. Don't ask me why. As for uBlock Origin it's not as active as BDTL & ABS. Don't ask me why again for I tested the 3 of them together at vxvalult.net and malc0de. A few days back ABS has a new release but after these few days of testing at vxvault.net and malc0de it seems very inactive as compared to the earlier extension/add-on. In fact, Google Safe Browsing and Firefox's Web Security seem to takeover together with BDTL/uBlock Origin. I gather that this new release of ABS is not effective and not worth the install so I had it removed. I removed not because of fellows' comments here, ok?
Kaspersky AntiRansomware Tool for Business
I have seen it in action before so I'm keeping it. After all I don't feel it as an extra even with antiransom features from HMPA and ZAL. No harm having an extra one.
Comodo Firewall (CFW)
I let it do its job as a firewall. As for sandboxing I seldom run any testing program or browser inside it. After all HMPA already protecting my browsing. My purpose of having CFW is to test its stability against my system due to some bad installation experience with previous version. This version seems stable so far. If it was unstable I would have thrown it out and used my previous PrivateFirewall.
Duplication of software features
Nowadays, software comes with many features and some do overlap at times. Can't be avoided if you want to use them. The only way out is to disable some features on one just to let the other run smoothly. Exclusions is useless for their real-time protection is still being affected. However, one has to decide whether to use the software if too many features are being disabled. I'm the user of my system and I'll monitor if the software/browser extension installed does impact and to what degree it'll cause my system to slow down or even perform weirdly.
My System Performance
I'm using MS SP3 Core i7 running Win Pro 64-bit. It's natural that if more software/browser extensions are installed the system's performance will be impacted. It's true of my system but I don't feel so great an impact that I need to uninstall many of my software or browser extensions.
Conclusion
MS SP3 has been out in the market coming to 2 years (I think) and I have not been infected with anything yet. My aim is to get a system which is over-protected rather than under-protected and gets an infection. There's no such a thing as adequate protection. And there's no single software that can 100% protect you. With an over-protected system I do not need to tie myself down when surfing the net like observing good safe surfing habits etc.Why should I restrict myself? The net is the world and I go where I like to (within limits). If I gets an infection it's also a good test of the robustness of my security system and the need to improve on it, no?
Like I said if my system screws up I just reformat it. That's all!
Thanks everyone for your critique.
