Malwarebytes Browser Guard vs Avast Online Security

Side-by-Side Comparison

Which Should You Choose?

Malwarebytes Browser Guard is the clear winner — well ahead of Avast Online Security despite Avast having far more reviews.

Malwarebytes Browser Guard rates 4.5 stars across 724 reviews, dramatically ahead of Avast Online Security's 2.1-star rating across a much larger sample of 26,350 reviews — meaning Avast's larger user base is actually reporting significantly lower satisfaction. Malwarebytes focuses on blocking malicious sites and unwanted content, while Avast Online Security is categorized under Social & Communication rather than pure security, requesting a narrower permission set. Given the size of the rating gap on a large review sample for Avast, Malwarebytes Browser Guard is the notably stronger-reviewed option.
