Our rating: 

4.5

Pros & Cons:

Small download size, high PUP/adware detection, strongest against fileless malware and active malware processes, cloud based, drag n drop scan support, good signatures, doesn't require updates, portable version available.
Slow scans, not good against zero-day malware, Zemana v2 better than v3, prone to false positives, requires 2 separate scans for best protection.

Our Review:

Installation:
As for me Zemana comes in 2 flavours, the superior portable v2.74 and the inferior installer version v3.0. Since v3.0 has removed custom scan support, added a nag screen for premium version, has no portable installer and removed drag n drop scans for files, I will be reviewing v2.74 instead here. The portable installation of Zemana is a 24MB installer and has an extremely light footprint. However the portable installation has no stealth mode and leaves traces behind. You can disable promotional messages from Zemana from Settings->General section. 
 
Interface:
Clean user interface showing a message that real-time protection has been turned off, which is not of concern for second opinion scanners. The main GUI reflects the current system status as "Clean" or "Infected", has last scan details as well as the last update check date. The log report shows the scan details showing the type and the results of the last scan. The top right corner of UI provides you access to Settings (compactly arranged on left side bar), Quarantine & Log reports. 
 
Features:
Scheduled scans are not available in the free portable version. Zemana allows you to create system restore points before cleaning infections but has to be manually turned on. Zemana has a unique feature to deep scan files and folders by drag n drop on its UI.  Simple file and folder exclusions can be defined for scans to whitelist them. Update checks have to be done manually. The advanced settings allow you to disable uploading unknown objects to scan cloud for analysis if needed. Detection of suspicious (CA root) certificates can be enabled from here. 
 
Usability:
Zemana is great at catching PUP's/adwares and still remains as one of the best scanners against fileless malware's and active malware processes. It has a good signature database but needs to be connected to cloud via the internet for best detection. Zemana doesn't require signature updates and auto-updates itself. 
Zemana is not good against zero day malwares and time taken to scan is a bit long albeit thorough. It's prone to false positives and requires 2 scans for full effectiveness: a) full scan b) custom users folder scan
