Get rid of it. Run the following 2 programs.
1.
Please download
AdwCleaner by Xplode onto your Desktop.
•Please close all open programs and internet browsers.
•Double click on adwcleaner.exe to run the tool.
•Click on Scan.
•After the scan you will need to click on clean for it to delete the adware.
•Your computer will be rebooted automatically. A text file will open after the restart.
•Please post the content of that logfile in your reply.
•You can find the logfile at C:\AdwCleaner[Sn].txt as well - n is the order number.
2.
Please download
Junkware Removal Tool to your desktop.
•Shutdown your antivirus to avoid any conflicts.
•Very important that you run the tool in this manner:
Right-mouse click JRT.exe and select Run as administrator
Do NOT just double-click it.
•The tool will open and start scanning your system.
•Please be patient as this can take a while to complete.
•On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
•Post the contents of JRT.txt in your next message.
Running both of them should get rid of that and any others you may have. If quickshare is installed, then you can assume you have smartbar installed as well, which should be removed as well.
