  • Avast Antivirus Software has consistently come in the middle of the pack when it comes to threat protection.

    It performs solidly in terms of real-time virus scanning, virus protection, and virus removal.

    Unfortunately, its lack of noteworthy additional protection features has caused it to remain in the shadows of more comprehensive antivirus software.

  • Avast Antivirus
  • However, Avast Internet Security 2019, the latest upgrade from the Avast Antivirus Software, delivers many security features that performed well during testing.

    That said, even basic version includes The Sandbox, a feature great anytime you're visiting sites or downloading files you may not completely trust.

    It isolates your browser when surfing or opening files to further protecting your PC from online threats.

    If you do online banking, shopping, and bill paying, the SafeZone feature protects your financial information and history.

    Since it's easy to reset and can't be accessed by other programs, it's great for protecting credit card numbers and banking information.


  • Avast has provided stable virus protection for its entire +20 year history.

    Many versions, including this year's, have earned several certifications recognizing its performance.

    While all versions of Avast generally do well in testing, Avast's Internet Security provides better all-around protection for people who use their computers for online banking, shopping, and bill paying.

  • Avast Security
  • Avast Internet Security is a good upgrade.

    For truly comprehensive security against a wide variety of threats, you'd be well-served to consider this version.

    The significant upgrades included in the Internet Security suite are its software firewall and antispam email filter.

    For anyone, and laptop or tablet PC users, in particular, a software firewall provides an extra layer of security.

    It builds a virtual moat around your PC to help protect you from hackers and malware.

    This one feature alone can be the difference between an infection or a hacker getting into your PC.

About these Tests:

Each product we review, including the three versions of Avast shown on this page, goes through multiple stages of tests.

We install each antivirus program onto freshly loaded and fully patched versions of Windows.

Then, we start the tests by using our own in-house samples of viruses and other malware.

These samples are of both well-known (or what should be well-known to the antivirus companies and brand new ones that are hitting our various anonymous honeypots across the Internet.

After measuring how the antivirus software performs against these different threats, we then compare our results against those from well-known independent test labs as a sanity check of sorts.

If our results are close to theirs, we know we're not the only ones seeing what we are; if the results are significantly out-of-line with our own, we redo the tests and add even more viruses and a larger set of malicious sites to test against.

Then, once we get those results back, they go live onto the site.

Antivirus Protection Tests (And Why They Matter)

Although there are a ton of different categories and subcategories of malware, really they fall into just a small handful of broad categories:
  1. Spyware
  2. Theft
  3. Destruction
Sure, the goal of any antivirus software you choose it to keep junk off your PC and to remove them if they get there. Any "good" antivirus or Internet security suite should be capable of that.

The reality is though that antivirus software varies tremendously both in quality and service, which is why our tests of Avira's antivirus products are more than just a tour of their features.

What We Prioritize (And You Should Too)

  1. Virus Prevention
  2. Virus Removal
  3. Affect on System Performance
  4. Technical Support
The obvious considerations are virus prevention and removal, both of which Avira does reasonably well.

As a brand, it's best described as a solid middle-of-the-pack performer with good performance as far as speed is concerned.

The one consideration most people leave as an after thought though is tech support.

Here Avast is a mixed bag.

On one hand, our anonymous tech support interactions with them were quite good; however, if you need help removing a serious virus infection, it's going to cost you, as Avast has one of the most expensive removal services out there, tipping the scales at $119 (USD).

So if free, U.S.-based tech support is a priority for you in your computer protection, your two choices are VIPRE Antivirus and ESET NOD32 Antivirus.
