Hyperlinks can be harmful to your computer and data. Click hyperlinks from trusted sources. Do you want to continue ?

While reading emails inside Outlook 2007, suddenly a security notice pops-up saying "Microsoft Office Outlook has identified a potential security concern. The application addin outlvba.dll has been disabled. Addins might contain viruses and other security hazards."
