It reportedly impacted businesses in more than 20 countries, affecting millions of computers worldwide. A computer virus involves self-replicating code that infects various segments of program files.
Viruses generally target a particular operating system or certain types of documents.
Worms often rename files with certain extensions or overwrite the data in files, either immediately or after laying dormant for some period of time. And, it is quite likely that future viruses will be more damaging. In the face of these circumstances, one important asset has been, and often is, overlooked - the possibility of insurance coverage for viruses and worms. These policies generally are written on a claims-made basis, meaning that they respond to claims first made while the policy is in effect. The policies often provide coverage for fraudulent or malicious acts against an insured's computer system, including viruses and worms.
