Current TBAV users can upgrade to NVC free of charge and will have their support contracts honored by Norman Data Defense. Norman also promises dramatically reduced renewal rates for TBAV customers whose contracts have run out. All in all, NVC is a no-brainer for those currently using TBAV, unless that is you want to save a bit of money by selecting a less expensive scanner. Norman Virus Control makes less sense for those already using another scanner or researching the purchase of a new scanner.
Pros: Easy to use, free definition updates, scans in the background, attractive interface
Cons: Expensive ($79.95), slower than VirusScan and Norton AntiVirus
