on-access scanner

Last modified: Thursday, May 17, 2007 

A type of antivirus program which runs in the background and actively scans your computer system constantly for viruses and other malicious threats, for the entire duration that your system is powered on, unless paused by the computer user. On-access scanners will monitor all system activity and automatically scan files which have been downloaded from the Internet or through e-mail. Contrast with on-demand scanner.
