With respect to the Best Free Antivirus 2015 competition, I'm starting a thread series where users of the various products will be joining together to state the Pro's and Con's of each antivirus/internet security software and why they think it is a contender or not for the Best Free Antivirus.

The first post will be updated by me with what user's think is good and bad about the product, so an informed decision can be made for newcomers.

Pros
Excellent detection rate of non-zero day threats
Does not *seem* to slow system (even with Pro and all modules installed)
Excellent high quality signature database with almost no false positives
Frequent updates to the signature database/components
Solid 'build quality' (with one exception detailed in Cons section)

Cons
Lack of day zero protection/comparatively weak heuristic protection vis a vis the competition
No firewall (even Pro just adds on/off switch for Windows Firewall to Avira interface)
At least a year long problem with updating on some hardware unless self-protection modules are disabled (1 machine is fine, other affected)
The launcher - pointless

Overall I love it, but am about to ditch it unless Avira finds a speedy fix to the update problem. It seems to be hardware related and only affects some machines, and the only way to fix it is to turn off the self-protection modules (advanced process protection and protect process from unwanted termination). On one machine it works fine, on the other, it won't update (even after a clean Windows 10 install). Love the product, but this update problem/security deactivation makes me unwilling to stick with it.

Pros
Good protection

Cons
The launcher is useless and it's using way to much memory.
0-Day protection is not that good (week vs non *.exe files).
If a safe file is detected you need to add to real-time and on-demand exception.

Overall = OK product :)

  • Popups
I haven't had a single pop-up after installing Avira for 2 weeks. Are you sure you tested it recently? Also the installer,has become free of any adware and the UI from advertisments.

Avira had high quality signature database and now with cloud scanning makes it stronger. Still Avira free lacks any behavioral shield, web scanning, sandboxing etc making it a weaker Anti Virus in dealing with Zero Day threats. If the Avira File system fails your system will most likely get infected by malware. Chance of getting infected by malware with Avira Free is much higher than Avast Free due to Avira's too much reliance with signature databases. Using Avira Free with other security solutions like Comodo Firewall offers good security though still costing Zero.
