Compare Avast Antivirus 2018 vs. Competition
Of course Avast is not the only company providing free antivirus, there are actually many others. Probably the second most popular free antivirus is AVG AntiVirus FREE which offers excellent level of protection with reasonable detection rates but is quite heavy on the system resources. Also you need to install AVG Zen which is required to run AVG antivirus. Lot of AVG users are complaining about the massive up-sell offers messaging. In October 2016 Avast has acquired AVG company, but both products are still available. Read our detailed Avast vs. AVG comparison review.
Another very good option of free protection comes from Germany. Avira Free Security Suite 2017 (former Avira Free Antivirus) is the best free protection you can have. Avira is regularly the winner of independent tests (AV-Comparatives, AV-TEST) in detection, false positives and performance. Plus it comes with advanced features like anti-ransomware, free VPN (500 MB / month) and PC speed optimizer. The biggest disadvantage is a heavy effort to monetize free users and up-sell them to paid version through annoying pop-ups. Also the user interface is busy, old fashioned and hard to understand. Read our detailed Avast vs. Avira comparison review.
