Free Download & Review of Avast GrimeFighter 2020

IMPORTANT NOTE: In July 2015 Avast GrimeFighter has been replaced by Avast Cleanup.

Avast GrimeFighter Overview and Free Download

Avast GrimeFighter is a tool for improving and optimizing the speed of your computer. GrimeFighter is the premium component of the Avast Antivirus, so you can get it even if you are using the free version.

This handy application basically does three things – 1) Improves your computer boot time; 2) Increases your computer speed; and 3) Provides you more free hard-drive space.

GrimeFighter free scan is available in all Avast antivirus solutions, Free Antivirus including. To run the free scan just open your Avast interface, go to ‘SCAN‘ and select ‘Scan for performance issues‘. You should get the following screen with the scan results. For the actual clean-up and speed-up process, you have to activate GrimeFighter.

Avast GrimeFighter 2017 Free Scan Summary

GrimeFighter scans your Windows system for present ‘grime’ like malware, spyware, or intrusive toolbars. Also it scans for unnecessary programs which are being run at the start-up of your Windows, and optimizes your system settings to make your computer runs smoother. For making up more free space it scans for redundant files on your hard-drive.

You can download the free scan tool from the official Avast website or click on the button below.

Avast GrimeFighter Pricing/Licensing

Unfortunately Avast GrimeFighter is not entirely for free. Though you can download the free scan tool but it only scans your computer (if it’s compatible) and shows you what the full version can do – as on the scan summary screen above.

If you want to actually clean and speed-up your computer, you have to purchase the full license (activation code). Which is on the other quite cheap if you consider how great and useful this product is. Pricing is as follows – 1-year license for $19.99; 2-year for $39.99, and 3-year for $109.99. 30-day money back guarantee as always.

If you decide to purchase the full license, just open your Avast and go to ‘Tools’ » ‘GrimeFighter’ » ‘Optimize My PC’ and select the subscription length.

Avast GrimeFighter Pop-ups and How To Disable Them

You can sometimes see the Avast GrimeFighter pop-up notification coming from your Avast antivirus. Usually it says ‘Performance Alert! We found X bits of evidence that Grime is slowing down your computer.‘ and has the blue button ‘Optimize My PC‘ at the bottom.

For some users these pop-ups can be quite annoying. If you want to get rid of these pop-ups just check our ‘Ultimate Guide to Disabling Avast Pop-up Notifications‘.
