Viruses are of two type: Resident viruses & Non-Resident viruses.on infection the resident viruses leaves their resident part in RAM and are active till the system is re-booted.
While infecting, virus scans comp. memory to check whether its copy is present there or not. After infecting RAM virus searches the free space on hard disk and replicates itself. here, it may define some interrupts necessary for seeking files to be infected to have destructive effects as weak as making effects on sound or video.
