Yes, a recently installed add-on could be the problem. If the disabling of add-ons doesn't seem to help then
do a couple of scans for adware and malware.
Scan your computer using this: AdwCleaner Download
Close all open programs and internet browsers.
Double click on adwcleaner.exe to run the tool.
Click on Delete.
Confirm each time with Ok.
You will be prompted to restart your computer. 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[S1].txt as well.
