Ans 1:
A computer virus is a malware program that, when executed, replicates by inserting copies of itself (possibly modified) into othercomputer programs, data files, or the boot sector of the hard drive; when this replication succeeds, the affected areas are then said to be "infected". Viruses often perform some type of harmful activity on infected hosts, such as stealing hard disk space or CPU time, accessing private information, corrupting data, displaying political or humorous messages on the user's screen, spamming their contacts,logging their keystrokes, or even rendering the computer useless. However, not all viruses carry a destructive payload or attempt to hide themselves—the defining characteristic of viruses is that they are self-replicating computer programs which install themselves without user consent.
Ans 2:
A computer virus or worm is a self-replicating program that can spread by email or by inserting copies of itself into other programs or documents. Most viruses or worms aremalicious programs designed to infect and gain control over a computer without the owner’s knowledge.
