Total PC Defender 2010 is a rogue security program which spreads via the Internet by using Trojans and fake online security websites. Total PC Defender 2010 is installed on victim computers without the user’s approval. It will secretly enter the system before modifying settings and registry entries to have itself run whenever Windows is operating. Once active, computer users may experience constant security alert pop-ups advertising Total PC Defender 2010. Total PC Defender 2010 runs its own virus scan which detects false threats on the computer to mislead users into getting the licensed version of this useless program. Total PC Defender 2010 poses a huge security threat to PC safety and should be removed immediately.
