Besides the detecting of the viruses, antivirus programs also have utilities to remove or repair infected programs or files. Some damaged files cannot be repaired and must be replaced with uninfected reinforcemen t files. The... ! hmm . . . . very intresting and a great explination of how a virus organise so it is not too technical and basically anyone can find out. great commendation material Informative, but it doesn flow together well. to a greater extent of a point form guide, than a scripted report.
