Unauthorized Access Blocked

Hi

 

I keep getting these instances onmy Norton Internet Security. It either says -Unauthorized Access Blocked (allocate Virtual memory) the Actor is logitech\lvmvfm\lvprcsrv.exe - something to do with my webcam software. My webcam is not connected.

 

Or..

 

It says Unauthorized Access Blocked (Send Terminate Message to Window) Actor is windows\explorer.exe

 

Sometimes they happen even when I'm not using my computer, but I can hear a sudden surge in the harddrive, and then I check and usually the history has recorded the Allocate Virtual memory incident.

 

Should I be Concerned?

 

Thanks,

Gary
