Thank you for the clear instructions on how to get rid of Grimefighter. I am perfectly capable of optimizing my own system. Plus the lack of information it gives you and requires you to pay to “optimize” something unknown is pure rubbish. I guess I shouldn’t complain too much since I have the free version of avast.

Thanks. I agree with Menchii. Feel I can (and have) complain as we have a 3 year license for 10 PC’s and this aggressive upselling is enough to drive me to another anti-virus program. That’s with over 500 days left on the license. Very upset.

Thank you for the help uninstalling, removing disabling this piece of crapware /crap ware. Grimefighter aka Grime fighter by avast is anoying adware that borders malware and it didn’t come impressed installed but snuck in through a regular progam update unannouced than started its assualt with vague information that leads to scareware screen of pay us this is the crap of virus scanners of malicious download fame . I thank you highly for helping me get this crap and grime fighter’s bullshit Kobayashi , Dale Jumpshot Jr. , Beef, Torque , Sir Jeffrey , Mario , Dr. Liza , Zilch , Maximus, Holmes, Nikita scum ware off the computer. The first thing such a program should do is remove itself. This shit was digusting and looks like a virus or scriptkiddie from 4 channel /b designed it and is likely to kill your computer like Avast did on their previous update mistake. If you downloading custom might be option but if installed you get no warning than after you are infected with the malware flashing or better side hijacking your screen with scare ware messages. The program may be free but this crap is not acceptable. Caution should be used and removing Grimefighter a must. I hope my comment helps your page rise in search engines because Avast’s forums make you register (so they can then spam most likely) to see the removal guide a few people posted while the rest is accusing incompetents that praise avast as doing no wrong. Claiming the program isn’t installed yet acknowledging the fact it did scan the computer or it would just be advert. To use it you have to pay an absurd amount to unlock the features already downloaded just hidden from the user. With this malware grimefighter being outed publicly and the complaints, one has to wonder how much more crap and calling home shitware they have installed with the latest updates. Thanks for giving the burned users a place to post warnings for others and for the help of removing this garbage. Especially since Grimefighter is not easy to find in windows 7 for add remove program option has been changed. Anyone who came here uninstall and start shopping for another anti-virus app because this is going down the mcafee and norton road of bloatware loaded with scareware to leach more money and playing definition games and ripping you off for more money to do something that is as easy as opening task manager by ctrl control alt and del delete keys down to access it. or run msconfig an check boxes which guess what grimefight has missing in services. Avast hit this shiturd crapware malware and made removal difficult. I can only hope malware bytes, spybot and other programs start removing it has unwanted program for classification.

I just renewed Avast and while doing that they installed Google Chrome and google tool bar. I was going to log into my bank.(I use Internet Explorer) Every time I clicked ont eht bank in favorites aGoogle Chrome took over. I uninstalled Google Chrome and the same thing kept happening. I called their support number and the lady said I had to pay to fix this. Ove a hundred dollars. Then she said a cheaper price or a year of their service for much more. I said I did not want to pay for their help. She sounded upset. I found out that Google tool bar was doing it. I uninstalled it and that computer is working good now. I just use that for the bank I do not serf with that one. I had a computer with Windows 7 and that thing I had to wipe the drive and reinstall everything. It works good. I took it off this laptop, but it is real slow. I think this one also needs a drive wipe and reinstall. I used Avast for years. I never had trouble until buying it.

May be you’ve not followed the instructions step by step or it is not installed for you. If you don’t know you can disable it also. Check this http://techdows.com/2014/03/disable-avast-grimefighter-and-browser-cleanup-popup.html. Ask me if you’ve any doubts.

I’m hoping you can help me, Venkat eswarlu.

My Toshiba Satellite laptop (Windows XP / Version 2002 / Service pack 3) is running slow. I usually avoid speed-up software, but I trusted Avast after years of using it so I actually paid £19.99 to download Grimefighter.

After downloading, installing and starting, Grimefighter sedated my computer then a full-screen message said it could not run on my computer. I phoned Avast and was told to use the Avast support website to get a refund. After several messages to Avast I have heard nothing from Avast apart from automatic email acknowledgments.

The problem is that I can’t get rid of Grimefighter. I tried to uninstall Grimefighter using my Control Panel – Add / Remove. As Grimefighter was not listed, I uninstalled Avast – but Grimefighter was still there. I then searched for and deleted all files called Grimefighter and Jumpshot but Grimefighter was still there, even though Search finds nothing.

Avast have not helped at all, but I got several suggestion on Avast forum, including from a techie who said re-install Avast and untick Grimefighter. I did so but Grimefighter was still there. I have done this several times to be sure, but Grimefighter remains.

I have tried Control Panel Add/Remove and Change which shows Grimefighter already unticked – but it is still there and loads when it feels like it.

From another forum suggestion I tried Avastclear which required me to use Safe mode and reboot. On opening, Grimefighter loaded and started the same old sedating the computer then being unable to run. If I tried Setup, I got the choice between Grimefighter (now in Safe mode) or Windows.

I wish I had not bothered with Grime fighter (and never heard of Avast). It is more like an invisible virus than controllable software. I would have thought that any quality software would have the means to uninstall it.

The forum seems to have given up and Avast are not interested. I would appreciate any help you could offer.

Thanks.

You’ve downloaded and run standalone version of Grimefighter that doesn’t install on your computer and that’s why you’d not find its entry in list of installed programs.
Next its portable one, so no harm is done to your computer, but it runs from downloaded location, but extracts all files it needs including GrimeFighterApp.exe to a temp direcoty can be with name like this 7zS59C3.tmp in your computer, you can find this in C:\Users\username\AppData\Local\Temp. (Remember AppData folder will be hidden, make sure Explorer to show hidden files and folders before accesing that path/)
I suggest you to find and delete GrimeFighterApp.exe residing folder in temp using Windows Explorer search.
Don’t fear, GrimeeFighter it self allows to revert undo all the changes if it had made something wrong, you can use that.
Are you able to enter into Windows and use your PC? Are you using Avast? if so you can disable it using the steps mentioned here http://techdows.com/2014/03/disable-avast-grimefighter-and-browser-cleanup-popup.html

Thanks for the information.
I looked for the files you mention using Windows Explorer (set to show hidden files) but the layout is different in my computer.
On my laptop the main files in C: are
C:\Documents and Settings
C:\I386
C:\Program Files
C:\Windows

There are some other files which have nothing relevant in them:
Freeserve
Downloads
unzipped
VALUEADD

The nearest I could find to C:\Users\username\AppData\Local\Temp are:

C:\Documents and Settings\All Users\Application Data
C:\Documents and Settings\Default User\Application Data
C:\Documents and Settings\Default User\Local Settings\Application Data
C:\Documents and Settings\Stan\Application Data
C:\Documents and Settings\Stan\Local Settings\Application Data\Temp
C:\Documents and Settings\Stan\Local Settings\Temp

The only file similar to the temp file you suggested is:
C:\Documents and Settings\Stan\Local Settings\Temp\7zS135.tmp

File 7zS135.tmp contains a lot of .dll files plus two folders:
locales – which contains files with extension .pak
Resources – which contains file resources.pak

I haven’t managed to find GrimeFighterApp.exe yet.

I do still have Avast and I can run Windows if I press function F2 to go into Setup and choose Windows. If I don’t do this it usually goes into Grimefighter on booting up.
I tried to disable Grimefighter using Avast Settings>Tools, select ‘Customize’ but Grimefighter does not show up in the options.

There are only three options:
Enable software updater
Automatically download updates if possible
Notifications (popups) enabled

How about running GrimeFighter on booting? run it and let it make the changes, once it finishes you might get regular Windows boot option.

Stan March 28, 2014 at 2:52 pm

If I let Grimefighter run, it starts sedating the computer then displays full screen: “Houston, abort shuttle launch. We can’t run Grimefighter on this computer”, as it has done since I first installed it.

This screen then allows only two choices:

1/ to click a button that takes me to another full screen, headed chrome://jumpshot/content/browse.html which only allows me to get back to the “Houston, abort shuttle launch. We can’t run Grimefighter on this computer” screen.

2/ to click the close X in the corner and go to another full screen which only allows Reboot or Shutdown. Reboot gets me back to the original choice of Grimefighter or Windows in Setup. Similarly with Shutdown when I boot up again.

So running Grimefighter only delays going into Setup anyway.

I thought I was buying helpful software but it a useless virus that dominates my computer. Could there be another anti-virus software that would recognise Grimefighter as a virus and remove it?

Boot into Windows and try to restore system to earlier state before running Grimefighter, have you tried this? last option is to format c (OS) drive.

I read your email. its better for you to seek help of advanced user nearby or technician, can’t do much without the system in front of me.

I installed it by accident…I was going to opt out of the….tell the world about what sites I visit….but it had already downloaded so I ran it. It came up and said it couldn’t run the computer scan, not my fault but theirs.

Well, I just got a notification from Avast too about that Crimefighter thing. Was almost at the point of paying for a year for it, but then I found this site. It was a great help :)

Concurring on the point of where it becomes scareware. Was a bit scared to when I saw the problems, but now I am just a bit upset with Avast.

Am thinking of completely switching to Malwere Bytes Anti Malware. :)
