My computer has unwittingly downloaded programs that i can not un- install.
When i use the internet, my usual Google home page does not come up. Instead, i get some random browser. Other programs are also not working properly ans something keeps asking me to start a scan on my computer.
Please can you help me remedy the situation and bring my laptop back to good health.

 Lots of things you can try.  I guess I'd start with the free version of Malwarebytes.  Get it up to date, boot to Safe Mode and do a full system scan with it and your antivirus.  Reboot to normal mode.  If the problem persists, run SFC from an elevated command prompt.  Click Start, go to the search box and type CMD.  Then right-click CMD.EXE and click Run as administrator.  From the command prompt type SFC /scannow.

 

Good luck.


Everyone with a computer should back his system up to an external hard drive regularly.  :thumbsup:

In many cases these issues are the result of unwanted toolbars, add-ons/plug-ins, and browser extensions which come bundled with other free software (often without the knowledge or consent of the user). They can often be the source of various issues and problems to include Adware, pop-up ads browser hijacking which may change your home page and search engine, and user profile corruption. As such many of them are classified as Potentially Unwanted Programs (PUPs).

Many toolbars and Add-ons can be removed from within its program group Uninstall shortcut in Start Menu > All Programs or by using Add/Remove Programs or Programs and Features in Control Panel, so always check there first. With most adware/junkware it is strongly recommended to deal with it like a legitimate program and uninstall from Programs and Features or Add/Remove Programs in the Control Panel. In most cases, using the uninstaller of the adware not only removes it more effectively, but it also restores any changed configuration.

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: Some programs can be difficult to remove if their services and running processes are not disabled or turned off prior to attempting removal because they are in use. As such, it is easier to uninstall after booting into safe mode so there are less processes which can interfere with uninstalling the program.

Remove anything else (newly installed programs) you do not recognize.

The next place to check is your browser extensions and add-ons/plug-ins.

After doing the above...continue as follows:

Please download and use the following tools (in the order listed) which will search for and remove many potentially unwanted programs (PUPs), adware, toolbars, browser hijackers, extensions, add-ons and other junkware as well as related registry entries (values, keys) and remnants.

RKill created by Grinler (aka Lawrence Abrams), the site owner of BleepingComputer.
AdwCleaner created by Xplode.
Junkware Removal Tool created by thisisu.

1. Double-click on RKill to launch the tool. A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully. A log file will be created and saved to the root directory, C:\RKill.log. Copy and paste the contents of RKill.log in your next reply.

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

2. 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.
  • After reviewing the log, 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 and uncheck any items you want to keep (except you cannot uncheck Chrome and Firefox preferences lines).


Close all open programs and shut down any protection/security software to avoid potential conflicts.

3. 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.
.
4. As a final step, download, install and perform a THREAT SCAN with Malwarebytes Anti-Malware 2.0. Be sure to print out and follow these instructions.
