Most Dell Systems Have Antivirus Software Pre-Installed

Note: For more information on different types of viruses, spyware and malware that can infect your computer see article What are the different types of Viruses, Spyware and Malware that can infect my computer?

The use of multiple anti-virus programs may cause your system to lockup. Antivirus programs come pre-installed on most Dell Computers, so customers sometimes install other antivirus programs without realizing that there is already a system installed. If you decide to install an alternate antivirus software, it is important that you first uninstall any other antivirus programs that may be running on your computer.
