Which one is for you

Pick ClamAV if

  • Fits if you run Linux or a mail server and want a free scanner
  • Works for a sysadmin who's comfortable on the command line

Look elsewhere if

  • Not for you if you want a desktop antivirus with a window, because there's no graphical app
  • Skip it if you want real-time protection on Windows or Mac, as on-access scanning is documented for Linux only
  • Too light for your only protection, since the docs say it isn't a traditional antivirus or endpoint suite
  • Watch out: it wants about 3 GiB of RAM and 5 GiB of free disk with the standard database

Pick ESET if

  • Fits if you want antivirus on one PC or Mac without a pile of extras
  • Works for buyers who'd rather pay for 2 years at once, which takes 15% off

Look elsewhere if

  • Not for you if your household runs on iPhones, as there's no iPhone app on record
  • Skip it if a VPN matters, as it starts at Premium, $79.99 a year, and covers only 3 devices there
  • Watch out: there's no free plan, so when the 30-day trial ends you pay or you're unprotected
  • Pricey if you want identity protection, as Ultimate is $179.99 a year, sold for 5 or 10 devices only, and its identity protection is US-based
  • Watch out: small offices are sent to a separate plan, Small Business Security, at $179.99 a year for 5 devices

How we grade them

2.4GPAClamAVFair2.6GPAESETGood
Value for money
AFree and open source under the GPL v2, with signature updates from Cisco. Anyone can download and run it.
CHOME Security Essential is $69.99 a year for 5 devices, with no first-year deal on record, so two years cost $139.98, about $5.83 a month. That's above the dearer quarter of antivirus but short of the dearest tenth. A 2-year term takes 15% off.
Free plan and trial
AFree outright, with no plan limits on record. The docs suggest 3 GiB of RAM and 5 GiB of disk for the standard database.
CNo free version, but a 30-day free trial with no credit card. When it ends, you pay or you're unprotected.
Features
DCommand-line and daemon scanning, archive support, signed databases and mail gateway focus. The docs point to Cisco Secure Endpoint for a full antivirus.
BReal-time protection, a secured browser for banking, a firewall, and checks on your router and the other devices on your home network. Premium adds a VPN and file and USB encryption, and Ultimate US identity protection. Only the VPN is stingy: 3 devices on Premium.
Ease of use
DNo store rating on record, and you work through a command line and config files.
BNo store rating on record. It's software you install and leave running, with nothing to set up first.
Platforms and integrations
CWindows, Mac and Linux, but computers only: no phone app and no graphical interface.
BWindows, Mac and Android, and the VPN runs on a home router too. There's no iPhone app on record and no API, so B is the ceiling.

Key features

ClamAV

Command-line and daemon scanning
Includes a command-line scanner for on-demand file scans and a multi-threaded scanner daemon, with an automatic signature updater.
Mail gateway focus
The docs describe it as designed especially for e-mail scanning on mail gateways, and the About page lists a milter interface for sendmail.
Archive and file format support
Scans inside archives such as Zip, RAR, 7Zip, Tar and ISO, and reads PE, ELF and Mach-O executables, Office files, PDF and HTML.
On-access scanning on Linux
The ClamOnAcc client for the ClamD daemon scans files as they are accessed on modern Linux, and can block access until a file has been scanned.
Signed signature databases
Signature databases are signed, so the scanner only executes trusted definitions, and the databases are updated several times a day.

ESET

Real-time malware protection
Blocks viruses, ransomware, spyware and phishing as they arrive, with AI-based detection aimed at new threats.
Safe banking and browsing
A secured browser mode for banking and shopping that helps keep payment details away from phishing pages and snooping software.

Premium and Ultimate include a no-logs VPN with unlimited traffic, split tunneling on desktop and Android, and a version that runs on a home router.
File encryption
Premium and Ultimate encrypt sensitive files and USB drives and let only trusted apps change protected folders.

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
