NIS & Google Chrome- opening new tab Internet screen freezes

I just installed Norton Internet Security, replacing Norton Antivirus use for several years.  Now with new NIS installed, whenever I click on a link within an email or from a google search, the new tab screen, when it appears, freezes.  I cannot scroll using my mouse nor will the screen scroll using the right hand slider.  If I click back to the former tab and then return to the new tab, everything then works. However, if I reload the same tab, it doesn't correct anything; the screen is still frozen.

 

I installed NIS on my wife's laptop and she does not experience this problem.  Both machines are running Windows 7.

 

I did not find anything similar on the forums

 

Any suggestions anyone?
