Avast! was established in 1988 as ALWIL Software cooperative in the Czech Republic after mathematics researcher Paul Baudis wrote a computer program able to remove the infamous Vienna Virus. Since that time, Avast! has continued expanding its antivirus technologies as well as its worldwide user base. Avast! currently protects over 200 million active devices in 41 languages.

The Good

  • Free antivirus
  • Great features
  • Crowdsourcing

Avast! offers free antivirus and anti-spyware protection for PC and for Mac. Coverage with a paid subscription includes a slew of additional security features. One feature to pay attention to is Avast!’s SafeZone protection for secured payments and banking. Though it’s not a typical focus of antivirus protection, improved financial security is a fast-growing need online. SafeZone allows users to control settings for specific websites dealing with financial transactions—such as online banking accounts, booking hotels and flights, online shopping, or any other type of money transfer—to launch in special windows that keep your financial information private.

Another great feature is the value Avast! places on crowdsourcing. The company encourages customers to submit information about specific malware they encounter to Avast!’s ever-expanding database of threats. This supplements the live updates maintained by antivirus professionals in Avast!’s labs.

The Bad

  • No social media protection
  • Can become pricey

Though Avast! offers extensive virus, malware, spam, and phishing protection, as well as particular attention to financial accounts, the company’s antivirus products don’t offer any protection specific to social media accounts. They don’t monitor social media activity to alert you to suspicious activity that might suggest your accounts are being compromised. Additionally, Avast!’s subscriptions may seem relatively inexpensive, but the prices we’ve listed are only for securing one device. If you are looking to secure multiple computers, be sure to compare the prices for securing multiple devices, which can get pretty steep.

The Bottom Line

Avast! has an extensive worldwide presence as well as an impressive, consistent performance record with AV-Test and AV-Comparatives. This company is a good choice for antivirus protection. At the very least, you’ve got nothing to lose with the free subscription option and 30-day trials for the other products!

Avast!’s performance scores have greatly improved over the last few years, instilling confidence in consumers and signaling a bright future for this company’s products.  AV-Test’s real world testing for web and email threats revealed that Avast! offers above average protection in those areas. Avast! also earned a perfect usability score in the most recent (October 2013) test measuring false detections of legitimate software. AV-Comparatives has repeatedly awarded Avast! its highest rating—advanced plus—for real world protection.

Tune-up & Speed

Avast!’s antivirus products do not have a tune-up feature included, but Avast! is currently working on updating its separate-subscription scan tool that can be used to free your PC of clutter to get it back up to speed. This tool, which is called the avast! GrimeFighter, detects hardware components in danger of failure and removes trialware, pop-ups, bloated toolbars, and junk files that hinder your computer’s performance. It will be available for download again once the Windows 8 version is updated.
