Sonic Activation Module Box

I installed some anti-virus programs last week.  This "Sonic Activation Module" starting popping up. Now, everytime I startup my computer I get this Sonic program box stating that I need to install the CD.  I have to hit on numerous times before the module will go away.  Then, at the next Start-Up, it starts all over again. I believe that the "Sonic Activation Module" Box is from an earlier Sonic program that I un-installed a long time age.  I believe there is still part of the program that didn't un-install.  Can someone help me to get rid of this annoying problem. Thanks
