Symantec Norton Secuirty Scan Symantec Norton Security Scan Promotion is Invasion of My Privacy Internet

Symantec has a very annoying promotional Scheme. While I log on to my normal websites Norton Security Scan places a banner on my bottom web bar. I am not really annoyed with what I consider a sub standard company promoting their version of what I consider outdated security "But" when they put an ad on my computer that does not have the capability of being deleted I think this is underhanded as well as annoying. There is no simple way of eliminating it short of logging off.So based on their underhanded schemes and their annoying tactics I just want anyone who is considering Symantec Norton Security to be aware of their methods for annoying me with their ads.
