2. 1. Bitdefender Antivirus Free Edition
Given a new lease of life, with fast virus-busting and a clean interface
As if, in our previous roundup, the folks at BitDefender heard us moaning about the fact
that its free product hadn't had its engine updated since 2013, along comes a brand
version at last.
Key features
Fast scanning
Excellent virus detection
Phishing protection

4. 2. Avast Free Antivirus
A much-improved free antivirus suite, bolstered by a new, expanded userbase
Avast and AVG haven't yet fully merged, despite the former formally acquiring the latter in
mid-2016. The newly combined company says the two free antivirus products will remain
separate, although there's apparently a joint AV package on the way soon. Obviously,
Avast now has a lot more data to work with, having expanded its effective userbase (and,
therefore, its threat detection network) to a whopping 400 million users.
KEY FEATURES
Excellent virus detection
Gaming mode
Password manager
Malware scanner

6. 3. Sophos Home
A new entry on our list – but the perfect choice for a home full of PCs
Marketing itself as "business-grade security", Sophos Home does a little more than most
free antivirus software, and actually seems better suited to families.
You get standard antivirus and anti-malware protection, along with browser tools like anti-
phishing and, most importantly, content control. Combined with central management of
to 10 PCs, this means you can effectively lock down your kids' browsing options.
KEY FEATURES

Phishing protection

Protects up to 10 PCs

8. 4. Avira Free Antivirus
Great antivirus, but a little noisy for our liking
Avira Free Antivirus continues to score highly on AV-TEST's stringent testing program,
quashing 99.7% of tested threats, and it generally doesn't put too big a burden on your
hardware.
It has a clean, friendly interface, and throws up minimal false positives. The introduction of
free security suite to optionally run alongside it – with ransomware and phishing
a 500MB/month VPN and various speedup promises – just sweetens the deal. This is one
the best free antivirus packages of 2017.
KEY FEATURES
Excellent virus detection
Phishing protection
Built-in VPN
System optimization tools

10. 5. AVG Antivirus Free
Free, nice looking antivirus, but lacking in a couple of areas
There's a growing trend amongst some online pundits to label antivirus apps like AVG –
indeed, AVG specifically – as 'crapware'. We don't subscribe to that definition; if that term is
supposed to mean that these apps are ineffective or pointless, it's simply not true.
KEY FEATURES
Good virus detection
Phishing protection
System optimization tools

12. 6. Panda Free Antivirus
Feature-rich PC security, but not as lightweight as it promises
The eternal battle against popups doesn't exactly start well, with Panda's site throwing a huge banner up
shouting about a discount on the full version before you're even allowed to download the free one.

13. 7. 360 Total Security
Antivirus overloaded with features, with a potential sting in the tail
The specter of developer Qihoo's VW-esque cheating of AV tests seems to be lifting a little
these days, and it's hard not to recommend it when you consider exactly what it's offering
up for free: AV protection from several concurrent engines (BitDefender, Avira, and Qihoo's
own engines) along with reasonable extras like anti-phishing and a mobile app to help
manage multiple systems.
KEY FEATURES
Multiple virus scanners
Malware scanner
Phishing protection

15. 8. ZoneAlarm Free Antivirus + Firewall
Licensed antivirus and noisy alerts, tacked on to a solid firewall
ZoneAlarm's reputation in the firewall world precedes it, and while that particular aspect of
this all-in-one package isn't what we're really concerned with here, it's a solid extra if you
don't trust your router or Windows' built-in firewall.
KEY FEATURES
Malware scanner
Personal firewall
Identity protection
Online file backups

19. 10. Comodo Free Antivirus
Free AV that needs a little work before it's ready for widespread use
