Pros / ESET prevents unauthorized applications from accessing your webcam.

Cons / It doesn’t work on iOS devices.

 Verdict / ESET offers malware detection on Windows and Mac computers, as well as on Android mobile devices.

ESET Multi-Device Security comes with the Internet Security module for Windows computers, Cyber Security Pro for Mac computers, and ESET Mobile Security for Android tablets and cell phones. You can use the program on up to three devices at once, though there are packages available that give you protection for 10 devices. However, this computer protection software isn’t compatible with iOS mobile devices.

Windows Protection

Independent test labs found ESET has better than average malware detection on Windows 10 computers, and during our in-house testing, it consistently detected threats such as adware and keyloggers. It did cause some slowing on test computers, both in our own tests and in other labs’ evaluations.

You can use the program’s parental controls to monitor you kids’ online activity, and it has antitheft features that let you remotely lock your computer if it is lost or stolen. Another helpful feature is a gamer mode that automatically suspends notifications while you watch movies and play games in full screen without you having to manually enable it.

One of the best features included with ESET Multi-Device Security is its webcam protection. This function monitors your webcam to ensure unauthorized apps can’t access and turn it on without you knowing. This gives you an extra layer of security and privacy.

ESET Multi-Device Security is missing features some of its competitors have, like a file vault to store especially important data and a Windows registry cleaner, which deletes registry keys that are sometimes left behind when you uninstall an application. It also doesn’t have a file shredder to erase deleted files so they can’t be retrieved from your hard drive.

Mac Protection

This program had good results with tests performed on Macs, and it didn’t slow down the test computer. It also scored above average for detecting and blocking Windows threats on Mac machines. This is important since these threats, while not a problem for Mac users, can be accidentally sent, through email or file sharing, to family or friends that have Windows devices.

As with its Windows module, ESET includes antiphishing and safe banking tools. It gives you access to the parental controls and password manager. It scans Mac computers for any outdated software programs and other vulnerabilities and helps you find ways to patch them so you’re not helpless from ransomware, hackers and other viruses.

Mobile Protection

The Android mobile module alerts you if an application wants access too much private information or if an app poses no risk but might send you excessive alerts. The program has antitheft features that help you remotely locate, lock or wipe your phone. Also, it takes pictures of the thief. ESET includes antiphishing and call blocking features. Some competing products have additional features such as parental controls and password managers, but ESET doesn’t. ESET also does not support iOS devices. If you need iOS protection, consider Trend Micro Maximum Security that is compatible with all Mac devices.

User Experience

ESET Multi-Device Security doesn’t offer online backup. Online backup is especially useful If your computer crashes because of a virus; after the threat is removed, you can restore files housed in the online backup.

All protected devices can be viewed from the online dashboard. This is also where you install protection on new devices, initiate antitheft measures and renew license subscriptions. You can reach ESET’s customer support through online chat, or you can email or call the company between 6 a.m. and 5 p.m. Eastern time.
