Will avast! GrimeFighter speed up my old PC?

howto2_enQuestion of the week: I have seen your ads for GrimeFighter, but I don’t know if it will help me or not. I have an old laptop that’s really slow. Will GrimeFighter speed things up? How does it work?

Yes, GrimeFighter will speed your old laptop up, and more than that. We are quite proud of avast! GrimeFighter and see it as a complement to the services provided by avast! Antivirus, so I’m glad you asked this question. Read what one of our customers told us after using GrimeFighter on her old laptop.

Here’s a summary followed by a short video on how to get GrimeFighter for your PC.

Why do I need GrimeFighter?

about_cleanNew PCs come pre-loaded with what we call Grime - all kinds of clutter and trialware. Over time your PC gets bloated with more Grime; viruses, spyware, pop-ups, and toolbars, making it sluggish and difficult to use. GrimeFighter comes to the rescue as an easy-to-use, and dare I say, even fun, fully-automated optimization tool designed so that even a novice can tune up his computer.

Don’t get put off by the word “optimization.” This isn’t those scammy products advertised on late-night television – AVAST wouldn’t be a part of such things. GrimeFighter is a product that we stand behind and believe will help our users extend the life of their machines. (Windows XP users, we’re talking to you!)

Who can use GrimeFighter?

If your computer runs Microsoft Windows 7, Microsoft Windows Vista, or Microsoft Windows XP, then you’re good to go. Avast! GrimeFighter does not run on any Apple Mac OS.

There are some known incompatibility issues that we are working on. Please check before you start.

What can I expect when I use GrimeFighter?

If you run an avast! GrimeFighter scan for the first time on your computer, and you don’t have a license yet, you’ll need to purchase it. To do so, click ‘Optimize My PC’.

avast! GrimeFighter cleans and optimizes your PC

Depending upon the speed of your Internet connection, it may take a few seconds for all the necessary files to be downloaded and the scan to begin. Once it’s ready, you’ll be asked to restart your computer. Do that, and the scan will begin. You can surf the internet while it’s running.

The scan may take anywhere from 30 minutes to a maximum of four hours. If it takes longer, then something is not working properly, and you should exit the scan.

Once it’s all done, you will be prompted to clean things up automatically or you can modify the recommended changes before the final system cleanup. The final report gives you an easy-to-read summary of what was done to improve your computer’s security, performance, and privacy.

How do I purchase GrimeFighter?

avast! GrimeFighter comes as a 1, 2, or 3 year subscription. You can get it through avast! Antivirus 2014 products, and it’s also available as a standalone application. Try avast! GrimeFighter on your old, slow PC.

    This is the most annoying ad ever, I just spent $600 upgrading my PC, my windows rating is 7.2 and now I’m getting pop-ups dally saying I should throw out my sluggish PC! I don’t want to turn off all the popups just this one, anyone know how to block this or do I need to start looking for a new antivirus.

    Avast! Please weed out these popup ads from operating systems you officially don’t even support (Windows 8).

    It’s a really bad sign that the most visible effect of this product is to make one’s PC experience highly unpleasant. People paid money to use Grimefighter. They should not be punished for buying the product.

  • John in Brum

    When somebody is running with the free product I think it only fair that you appraise them of the advantages of the paid version, but when someone has bought your product and you are still bombarding them with ads is is just too much. I have used your products for years but am getting increasingly annoyed with the ads and am borderline thinking of jumping ship.

    Hi, what do you think? I bought Grimfighter for two years, some days ago. Two years? Yes – I have Avast for many years and I am very satisfied.

    After having installed and so on I wrote this. (Have to check if you understand)

    “Date: February 5, 2015 4:21:03 AM CST


    I paid for two years and got my license today to Grime

    I now sucseded to log in and perform what I suppose this
    program should do, up to the point when it askes me to log in again – and on
    the Grime Fighter platform/interface.

    When I try to write my emailadress there are signs abowe the
    field where I can write, with signs I can chose with the mouse/pointer. When I
    click on the sign @ or any other of the signs above the writingfield, nothing
    happenes and I cannot use the GrimeFighter program.

    Now I want to have a solution on this problem.

    If you can´t deliver a solution quickly, I want want to
    cancel what I bought, and get my money pack!

    Regards from Sweden,”

    My question: Do you understand my english?

    I got an answer from avast that doesnt snswer my question.
