Being logged out of web accounts by Norton?

Hello everyone!

 

I installed Norton AntiVirus 2011 for the first time on my laptop right around the beginning of January.  Installation went smoothly and the program seems to be running just fine.  However, I've noticed something that is a bit bothersome: ever since I installed Norton, I've found that I am continuously being logged out of my various online accounts, which my laptop used to keep me logged into until I manually logged out of them or cleared my cache.  This problem only seemed to occur precisely after I began running Norton on my machine, so I'm quite certain that it's a result of the program's settings or performance.  Is this a normal occurrence with Norton AntiVirus, and if so, is there a way to disable the setting that is conflicting with my computer's ability to indefinitely keep me logged into my online accounts?

 

Thanks in advance!
