Caution: Don't download or install the software from www.gimpshop.com
Today I searched for photo editing software and found GimpShop for windows, webpage is www.gimpshop.com, the site looks professional, so I downloaded the software and installed it. However, I noticed some strange activities during the installation, Firefox browser closed suddenly, Opera browser was being installed without my attention.
After the installation, I launched GimpShop and it seems no different that the original GIMP, so it's better to download and install the official GIMP. As the strange activities I encountered during the installation, so I check the installed software list of Windows and see that some unknown software were being installed.
When I launch Firefox browser, the homepage is always pointing to something about "freshy" and then redirects to Yahoo search. Even I reset the homepage to a blank page, it still behave the same. So the installer of GimpShop installed some unwanted software and Hijacking the homepage as well. The homepage of IE is pointing to "freshy" also.
Unwanted software installed and unwanted modification to you system:
- Freshy Toolbar (not really remember the name)
- Record Page
- Yahoo Toolbar for Firefox
- Hijacking homepage of Firefox and IE
- Disabled all Firefox extentions
Those unwanted software are easy to uninstall and you can change the homepage of IE simply. However, the Firefox homepage Hijacking and all extensions disabled are more difficult. You need to delete the file "C:\Users\YOURNAME\AppData\Roaming\Mozilla\Firefox\Profiles\PROFILE.default\user.js" and make the modification to Firefox "browser.startup.homepage" setting, enter "about:config" to the Firefox Location Bar (address bar), click "I'll be careful, I promise!" when asked, then search for "browser.startup.homepage" and change the value to the homepage you want or use "about:blank" to have a blank homepage.
For all the disabled extensions of Firefox, I don't know if there is an easy way to fix, but I just remove all extensions and then reinstall them.
Finally, you may download Malwarebytes free trail to scan your computer to look if any unknown malware exists.
