As a computer geek & programmer, I've used and tested the top 10 antiviruses that are in the market and never have I regretted using Avast. It's the anti-virus of my household. I have every device in my family installed Avast.


Quite happy!

Have been back with AVAST only recently (was with another for the last 2 years) and it no longer has annoying announcements and is truly lightweight.
A real pleasure to have on board!
Thank you AVAST team! :)

about Avast! Free Antivirus Feb 2016

I understand I get what I pay for buy getting a free AV, but I've never had such a negative experience with others. The AV is not only annoying (I don't need to get a loud notification every time my database updates itself) but a resource-hog. It slows down my computer on boot tremendously, and does a very, very slow scan when asked to. I had it for about a year but had to uninstall and go without it. Now my computer is a lot faster, and quite frankly, better off.


I like Avast, but it screws with some usage scenarios

Comment by ElDani
about Avast! Free Antivirus and AVG Anti-Virus Free Edition Jul 2015

Just today, I was looking to install and use a virtual environment (VirtualBox in this case) and I've had the devil of a time getting the virtualization to work. Without the use of Intels VT-x, the application I was trying to run within the virtual machine was unable to work properly, so this was a requirement.

In the end, after quite a bit of search on the Net, I found Avast to be the culprit. After disabling the checkbox "enable hardware-assisted virtualization" in the Avast settings and rebooting, it still failed to work properly, but now it also kept reminding me that my system was not entirely protected anymore. After uninstalling the Antivirus from Avast and rebooting the system, suddenly the desired function worked suddenly.

This is not the first time that Avast has interfered with my use of the computer, but so far I've always tolerated it. It is after all one of the best and most accurate Antivirus for free and that is a difficult combination to have. Now I'm using AVG Antivirus, my issue is fixed and I don't notice any major differences in performance or security.


I don't know why avast is so popular

Comment by blackboard
about Avast! Free Antivirus and Avira Antivirus Oct 2014

Why do people like Avast so much? It doesn't even make it into the top 15 at, so what's the upside in using it versus the many others that are better? The consistent best is always Avira for 100% real-world detection and a very low false positive rate. Panda is in second place because it also has 100% detection, but it has the worst false-positive rate. Emisoft, TrendMicro, BitDefender, and Kaspersky are also excellent, with high detection rates and very low false positives. Any of those choices are superior to Avast.

Avira is the clear winner for me because it always ranks high every month so I never need to worry if my antivirus is falling behind the others (it has always been #1 every time I have checked). Plus, Avira is free! It's made in Germany with fine German engineering. They make good stuff, always have.

Check the rankings yourself:

about Avast! Free Antivirus May 2012

Have been using since 2006, from the recommendation of a fellow gamer, and have yet to turn back. I have the android version installed on my rooted LG Optimus (which has a custom ROM), and REALLY like that (blocking spam texts for the win), and have also used it on Ubuntu for a home web server with apache2.

keeps my computer clean, doesn't slow it down, and sand-boxes weird programs that may try to hijack and/or install trojans to my computer, and it has blocked a few hacker injection attempts to my computer ( I awoke from a dead sleep at 2 am to my computer shouting "threat detected!", because I forgot to lower the volume after playing some video games, and left my computer on lol). It has also saved me from mistyped url's, on more than one occasion. The web rep supports 3 out of 4 of my favorite browsers (opera not supported), and it supports IE.

PROBLEM? I think not :D


Good, but still needs work

Comment by TBayAreaPat
about Avast! Free Antivirus Feb 2012

I got a redirect virus, and instead of rooting it out from an obvious .exe file, it kept zapping every webpage that I opened.
Also, it's difficult to turn off when preferred, so I end up installing it, using it once, and uninstalling it.

about Avast! Free Antivirus Jun 2011

Sorry, another resource hog. I tried to shut down pretty much all the shields and it still hangs Firefox 4 for several seconds while starting up. Funny thing is also that despite claims that it wont scan things (at least exe files) more than once a session it keeps doing the same thing over and over gain, at least with regard to Firefox. I guess this could be some isolated glitch with a specific software but I'm not impressed.


I've run Avast on several of my personal computers for years

Positive Comment by peterstaack
about Avast! Free Antivirus and Microsoft Security Essentials Jun 2011

I've run this on several of my personal computers for years, and have liked it. It's had its quirks, from version to version, but generally scores favorably in security tests and isn't too bad or a resource hog. I've strayed away, just a little, to Microsoft Security Essentials - which runs better on some of my aging hardware - but Avast! is my go-to for my own personal PCs.


Highly recommended

Highly recommended: I've been using the free Avast home edition for almost 2 years now, I can't recall having any serious issues since, it's unobtrusive & resource friendly, I build computer systems for Family & Friends and I always make sure Avast is installed, updated & ready to go.

Truly brilliant on Windows but an absolute dog on linux. Its a good thing that Linux is more secure than windows because you cant get this to work without adding extra code to allow for the large update sizes.
