Remove QuestScan (Uninstall Guide)

Tell your friends:
QuestScan is defined as adware by some anti-virus software applications (Avira, AVG, Ikarus). It is bundled with Hotbar and other free software. We were unable to find a traditional setup executable of Quest Scan. Whenever you are searching for any keyword on the address bar of your web browser it is redirected to search engine instead of searching for results in the Google or any other default search engine. It displays very limited and commercial results most of the time. Many users will likely find this a confusing experience because QuestScan changes the way you search the web. Besides, many users don't even know what QuestScan is. That's usually because only a small number of users will actually read the EULA or they will not fully understand they are consenting to the installation of advertising software. On the other hand, there's a great chance that such information is not always clearly presented. So, it is suggested to always look upon the files you are installing in your computer. Another problem is that some users find it difficult to remove QuestScan. If you are facing this problem with your web browser, please follow the steps in the removal guide below to remove QuestScan from your compute completely. If you have any further questions or concerns, please leave a comment below. Good luck and be safe online!

QuestScan removal instructions:

1. First of all, download recommended anti-malware software and run a full system scan. It will detect and remove this infection from your computer. You may then follow the manual removal instructions below to remove the leftover traces of this browser hijacker. Hopefully you won't have to do that.

2. Go to the Start Menu. Select Control PanelAdd/Remove Programs.
If you are using Windows Vista or Windows 7, select Control PanelUninstall a Program.

3. Search for QuestScan in the list. Select the program and click Remove button.

Alternate removal: run C:\Program Files\QuestScan\uninstall.exe

4. Scan your computer with anti-malware software to remove the leftovers of this adware from your computer.

if you look at internet options->search settings it shows you the search providers. now you probably already have removed questscan as search provider. but look closely at all the other search providers, when you hightlight them you see that at the bottom it shows "Search suggestion address" and "top result search address".. there you find questscan. So what you need to do is to add another search provider (go to microsoft) and remove all others..

First, look for the Questscan folder in Program Files - it does not show up in Start > Program Files (Start Menu).

Run the Uninstall executable, then delete all the remaining files in that folder (the uninstall run does NOT delete the exe file), then go back one folder and delete the Questscan folder itself. Now the plug-ins have nothing to run.

Second, search Run > regedit for questscan (Ctrl-F for start, then F3 to keep looking). Delete or right click > Modify any values you are allowed to (you may get no authorisation responses).

Third, Reboot.

Fourth, go back to the regedit and see if you can delete the rest of the Questscan entries.

CAUTION: While you are in there DO NOT BE TEMPTED TO FECK WITH THE OTHER ENTRIES. This the Registry - the brain of the Operating System, and it will NOT be happy with retarded idiots picking at and screwing with the entrails. Fiddle with the wrong entry and you could easily end up having to re-install Windows just to get it started again.

Finally, I suggest you check these folders for any unfamiliar file that is set to run at start-up (look for either an executable or a Shortcut). But still be careful what it does and what program it really belongs to:

C:\Documents and Settings\Administrator\Start Menu\Programs\Startup\
C:\Documents and Settings\All Users\Start Menu\Programs\Startup\
C:\Documents and Settings\Default User\Start Menu\Programs\Startup\

You could now run through the instructions on this web page - but I suspect you already did that.

How I got rid of questscan on firefox after nothing worked was scan the registry for questscan and deleted them the went in to the extentions folder of firefox C:\Program Files\Mozilla Firefox\extensions searched all the folders for anything containing questscan (found a jar file and another file that changes it back to questscan on start up)
then opened firefox config type "about:config" in the firefox address bar, then typed in questscan into the filter deleted the "extensions.questscan.init" and then right clicked keyword.URL and clicked reset.
and now hopefully no more questscan :)

2) Select options.
3) Under 'basics' you will see 'Search'
click 'Manage search engines' & remove quest scan.
4) Make sure to use google as default :)
