Comcast Norton Security Suite very slow

Colleagues,

 

Not sure how many people have downloaded and installed the Norton Security Suite now offered by Comcast.  I did (had McAffe before, from Comcast too) and my laptop is very slow in general.  In addition, if I get a message from the software or click on its icon in the system tray it freezes up momentarily.  When Norton is open and I try moving through its screens it also freezes momentarily every time.

 

Any suggestions?

 

Best regards, JD.
