"I'm running Symantec antivirus! How can my computer be infected?"
When virus definitions stop being updated, your computer becomes susceptible to infection even though your antivirus software keeps running. Unknowingly, you become at risk for any new viruses that might break out.
On June 22, 2009, Symantec virus definitions will cease updating. Don't be lulled into a false sense of security. Replace your old Symantec Antivirus software with the new Trend Micro Antivirus software today!
