This has been reported for several years, and it is "forced" Junkware / Advertising.
Personally, this has been another reason why I have never thought of using Chrome at all.
Lets try a few remover tools on it first -
Please download Rkill (courtesy of BleepingComputer.com) to your desktop.
There are 2 different versions. If one of them won't run then download and try to run the other one.
You only need to get one of these to run, not all of them.
You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.
See How To Temporarily Disable Your Anti-virus
iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/
* Double-click on the Rkill desktop icon to run the tool.
* A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
* If not, delete the file, then download and use the one provided in Link 2.
* Do not reboot until instructed.
* If the tool does not run from any of the links provided, please let me know.
If normal mode still doesn't work, run the tool from safe mode.
When the scan is done Notepad will open with rKill log.
Post it in your next reply.
NOTE. rKill.txt log will also be present on your desktop.
Please download AdwCleaner by Xplode to your desktop.
* Close all open programs and internet browsers.
* Double click on adwcleaner.exe to run the tool.
* Click on Scan. (Only Once)
* Check the listed items and untick any you do not want removed.
* Click on Clean (Only Once) and confirm with OK if asked
* NOTE : Your computer will be rebooted automatically. A text file will open after the restart.
* Please post the contents of that logfile with your next reply.
* You can find the logfile at C:\AdwCleaner[S0].txt as well.
Please download Junkware Removal Tool by thisisu to your desktop
Shut down your protection software now to avoid potential conflicts.
Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe 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 (JRT.txt) is saved to your desktop and will automatically open.
Post the contents of JRT.txt into your next message.
Download Security Check by Screen317 from HERE
* Save it to your Desktop.
