Frequently asked questions about Avast
Is Avast enough as my only antivirus?
Avast is among the top-tested antivirus suites and is enough as the sole real-time protection for the vast majority of users. For especially sensitive use cases (banking, sensitive research) many users add an on-demand scanner like Malwarebytes.
Does Avast slow down my computer?
In independent tests (AV-TEST, AV-Comparatives), Avast sits in the upper midrange for system impact. On modern hardware the slowdown is unnoticeable in daily use; older machines may experience brief lag during a full scan.
Does Avast work on Mac, Android and iOS?
Most Avast plans include licenses for Windows, Mac, Android and iOS – see platform list above. Note: on iOS the feature set is significantly smaller due to system restrictions.
Does Avast's price rise after the first year?
Like nearly every vendor, Avast's renewal price is higher than the introductory price – usually by 50–100%. The exact figure is in the price box above. Tip: turn off auto-renewal early and re-subscribe before expiry.
Can I try Avast before buying?
Yes. Avast offers a 30-day money-back guarantee with no strings, so you can try the suite risk-free. A separate free trial is also typically available directly on the vendor's website.
