Trojan Horse

A computer virus that poses as an innocuous program. A Trojan horse appears to be harmless so that the user will install it, but then performs damaging activities like data theft or file deletion. The virus derives its name from the legendary wooden horse used by the Greeks to clandestinely gain access to Troy.
