- Check your computer operating system's automatic update
settings to ensure you're receiving updates. - Software Updates
come in the form of software "patches" that replace defective
section of software code with corrected code. All software
manufacturers issue patches either on a regular schedule or as
defects are discovered. Malware can infiltrate a computer
through a software application that has not been patched. -
Check your software programs for updates that may be available
in the "Help" menu or on the software vendor's Web site. - Pay
attention to pop-up messages within a program: these may be
notices of available software updates. - Only apply updates from
trusted sites. Beware of download requests from pop-ups or
advertisements. - Create a new user on the computer that does
not have administrative privileges and use that account for your
primary logon when using the computer. Limit administrative
rights on users' workstations to help prevent the inadvertent
downloading of malware or other viruses.
