You have a Mindspark PUP. You can try just clicking on the bottom of the page where it says Restore New Tab Page. That might restore it to the original new tab page. If not try AdwCleaner:
Download : ADWCleaner to your desktop.
NOTE: If using Internet Explorer and get an alert that stops the program downloading, click on the warning and allow the download to complete.
Close all programs, pause your anti-virus and right click on the AdwCleaner icon and select Run As Admin.
Click on I agree
Click on Scan and follow the prompts. Let it run unhindered.
When done, click on the Clean & Repair button, and follow the prompts. Allow the system to reboot. After Reboot, AdwCleaner will popup. Hit View Log File. You will then be presented with the report. Copy & Paste this report on your next reply.
The report will be saved in the C:\AdwCleaner folder.
If that doesn't help then let's look at the FRST scans
- Get FRST from http://www.bleepingc...very-scan-tool/You need to download the appropriate tool for your PC. If you don't know if you have a 32 or 64 bit system get them both. Only one will work and that's the right one.
- Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
- Check the Addition.txt box
- Press Scan button.
- It will produce a log called FRST.txt in the same directory the tool is run from.
- Please copy and paste log back here.
- It will generate another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe). Please also paste that along with the FRST.txt into your reply.
