Avast Antivirus Essential Review

Author by

PROS / This antispyware software earned 100 percent from AV-Test in virus protection.

CONS / This program can cause some lag in your other programs, downloads, uploads and streaming content.

 VERDICT / While Avast protects against almost any threat your computer faces, the drain on your computer resources hurts its performance scores, giving it uneven AV-Test results.

Editor’s Note: Top Ten Reviews uses test results from the independent laboratory AV-Test as part of our review process for the best antispyware software. AV-Test looks specifically at protection, performance and usability on multiple versions of Windows operating systems, and it performs these evaluations several times throughout the year. We use the most current AV-Test scores available at the time of our review. It is possible that new AV-Test scores will be released after our review goes live on the site. We will consider these scores during our next review of the best antispyware software.

Avast Antivirus Essential continues to get better, and its AV-Test scores are continually improving. In the most recent AV-Test, Avast Antivirus Essential scored 5.5 out of 6 in malware detection. Its protection scores compete with the best, but its performance scores are not as high as those of the best spyware removal software. It uses a fair amount of computer resources – just enough to cause lag in certain applications, games and streaming services.

This spyware remover has a comprehensive collection of management tools for controlling scans, updates and spyware removal. Using this software, you can easily schedule quick, full and low-use scans. You can also monitor full-screen activities and limit the software to only critical activities when you are watching a movie or playing a game. It has the ability to scan at boot time, before the operating system starts, to detect present viruses that may attempt to activate when you power up your system.

In case you ever have a problem with your spyware removal software, Avast provides solid customer and technical support options. You can use telephone support 24 hours a day, even on weekends. The company provides free English-language support to the U.S. and Canada.

Avast hosts a forum and posts product information to Twitter, Facebook and a blog.


When you use Avast Antivirus Essential, you can rest assured that you're protected against almost all malware threats, but the trade-off is deceased performance in your other computer activities. Overall, this is solid antispyware protection with good support.
