This setup may cause performance issues, system instability or conflicts between programs, and can hinder the effectiveness of all installed antivirus products.
This setup configuration doesn't have a backup plan. We strongly recommend to add a backup solution for your data so that you can restore it in the case of an emergency.
Backing up allows the recovery of data that has been lost due of a malware attack (eg. ransomware) or a hard disk crash. In such events you might lose family photos, your music collection, documents, or financial data. Backups are fast and simple to perform so it should be done on a regular basis.
NANO AV seems good at detection.I've never heard of Nano AV, so I won't comment on that. In spite of that, having two companion AVs (Crystal Security, Zemana) and a specialized anti-ransomware solution (AppCheck) on top of the main AV is certainly overkill.
Also, syncing data on MEGA is not a system image backup solution.
I would also recommend to replace Adblock with uBlock Origin.
I'd say this setup is pretty risky until you look at these points.
Thanks for sharing.
I would stick to just Zemana Antilogger, alongside OSArmor & Syshardener. Syshardener also lets you add basic Firewall rules to further help and lockdown your OS.NANO Antivirus Free, Appcheck Anti Ransomware Free, Zemana AntiLogger (Only Identity Protection Enabled, Real time Protection disabled.)
