Hackers make use of viruses to get unauthorized access to computer systems and networks, often designed for monetary or perhaps informational gain as well as to cause damage. Hackers also may exploit weak points in software and systems to take power over devices and data. Ethical hackers work together with organizations for vulnerabilities and develop strategies to reduce risk.

Viruses can spread by way of email parts, instant information, websites with downloadable data files, peer-to-peer sites and physical media just like USB drives or—in early days of computing—floppy disks. They will damage or destroy data, corrupt program settings or alter software functions.

The best way to preserve a computer from viruses is to keep it up-to-date with the most recent software revisions. Those changes typically incorporate solutions to secureness vulnerabilities that hackers make use of.
