PSafe DFNDR Security: Antivirus, Anti-hacking & Cleaner earns top scores on malware detection and offers a range of handy tools at an affordable annual price.


Far-ranging security suite: In addition to virus detection, PSafe offers tools for clearing your cache, password-protecting apps, hiding photo galleries, controlling a misplaced phone, reducing your phone's temperature, and deleting older WhatsApp files.

Device and app scanning: By default, PSafe checks app downloads for malware. You can also manually initiate a scan of installed apps of your entire device.

High marks on malware detection: PSafe's mobile security app earned top scores on the suite of tests run by AV-Test, a security and antivirus research firm. The app performed well on both malware detection and battery use.

Annual subscription is a deal: An annual subscription runs $4.99. With comparable apps cost as much as $29.99 a year, PSafe's service is a deal.

Suspect suggestions: The DFNDR app prompts you to activate related utilities that offer questionable benefits. For example, the app requested I activate its Total Change battery monitor to ensure that I don't overcharge my Pixel 2 battery, a problem that may or may not exist.

A bit alarmist: After running a virus scan, the app alerted me that I needed to run it again. And periodically, the app sends a notification about an issue I need to fix, such as "55 apps causing heating."

Confusing or intrusive ads: In the main app window, ads and PSafe tools share a similar card-style design, making it challenging to figure out what's part of PSafe and what's an ad. Likewise, the app can display ads after completing a task for competing security apps, but they look like they are part of the PSafe suite.

Bottom Line

PSafe DFNDR Security: Antivirus, Anti-hacking & Cleaner earns high marks on antivirus protection and value, but it stumbles with confusing notifications and misleading ads.
