I'm new here, so sorry if I mixed up the forum topic where i can place my request.

I've downloaded Megapolis game from here and after installing it some kind of stuff was additionally installed on my PC I didn't want to be installed.

I don't know if this sstuff is malware or spyware (my avast antivirus keeps silence about this matter) but it changed my browser page and some other adjustments were made without my consent (an addon for browser was installed). I'd like to know how can I remove those additional things from my PC Windows 7 Ultimate? And if it is malware or something and can I work safely with such kind of things installed on my PC?

Many toolbars, add-ons/plug-ins, screensavers and browser extensions come bundled with other free third-party software (often without the knowledge or consent of the user). These can often be the source of various issues and problems to include Adware, browser hijacking which may change your home page and search engine, and user profile corruption.

Toolbars and add-ons install themselves in various areas of your operating system to include your browser and Windows Registry. Since some of their componets and behavior are determined to be harmful, anti-virus and anti-malware tools may detect and remove them as Potentially Unwanted Programs (PUPs).

Since installation sometimes occurs without your knowledge, folks are often left scratching their heads and asking "how did this get on my computer." Even if advised of a toolbar or Add-on, many folks do not know that it is optional and not necessary to install in order to operate the program. Some toolbars and Add-ons can be removed via Add/Remove Programs or the Programs and Features in Control Panel, so always check there first.

Alternatively, you can use a third-party utility like Revo Uninstaller Free or Portable and follow these instructions for using it. Revo will do a more thorough job of searching for and removing related registry entries, files and folders.

Note: Not all programs show up in Add/Remove Programs or Programs and Features. Some will have their own uninstaller by vendor design which can be found in the program's folder. Look for an uninstall icon (shortcut) from within its program group or open Window's Explorer, manually navigate to the program's folder itself, and look for an uninstaller file (i.e. uninstall.exe).

If the program is not listed in Add/Remove or Programs and Features, and there is no uninstaller in the program's folder, the next place to check is your browser Add-ons.

After doing the above...continue as follows:

Please download and run RKill by Grinler. A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.

Important: Do not reboot your computer until you complete the next step.

Please download AdwCleaner by Xplode and save to your Desktop.
  • Double-click on AdwCleaner.exe to run the tool.
    Vista/Windows 7/8 users right-click and select Run As Administrator.
  • Click on the Scan button.
  • AdwCleaner will begin...be patient as the scan may take some time to complete.
  • After the scan has finished, click on the Report button...a logfile (AdwCleaner[R0].txt) will open in Notepad for review.
  • Click on the Clean button.
  • Press OK when asked to close all programs and follow the onscreen prompts.
  • Press OK again to allow AdwCleaner to restart the computer and complete the removal process.
  • After rebooting, a logfile report (AdwCleaner[S0].txt) will open automatically.
  • Copy and paste the contents of that logfile in your next reply.
  • A copy of all logfiles are saved in the C:\AdwCleaner folder which was created when running the tool.
-- Note: The contents of the AdwCleaner log file may be confusing. Unless you see a program name that you recognize and know should not be removed, don't worry about it. If you see an entry you want to keep, return to AdwCleaner before cleaning...all detected items will be listed (and checked) in each tab. Click on each one and uncheck any items you want to keep (except you cannot uncheck Chrome and Firefox preferences lines).


Please download Junkware Removal Tool thisisujrt.gif by thisisu and save it to your Desktop.
  • Close all open programs and shut down any protection/security software now to avoid potential conflicts.
  • Double-click on JRT.exe to run the tool.
    Vista/Windows 7/8 users right-click and select Run As Administrator.
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log file named JRT.txt will automatically open and be saved to your Desktop.
  • Copy and paste the contents of JRT.txt in your next reply.
These tools will search for and remove many potentially unwanted programs (PUPs), adware, toolbars, browser hijackers, extensions, add-ons, browser helper objects (BHOs) and other junkware to include many related registry entries (values, keys) and remnants.

Wow, seems to me such problems as mine are quite widely spread here. You gave a very detailed and clear reply on my question! I appreciate this. 

Now it's time for me to follow all the steps you mentioned and see whether I succeed in uninstalling unwanted software.  :busy:
