It is basically a software program composed to cause damages or infiltrate computer devices without the owner indeveloped consent. It is basic term offered to recurrent miscellaneous forms of intrusive, hostile and also annoying code.Virus - is a software that copies itself and spreads without permission or knowledge of the owner.
