Question

Computer virus programs can remain ---------- and ---------- for a long time

Answer 1

Answer:

A computer virus is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code.When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.

Virus writers use social engineering deceptions and exploit detailed knowledge of security vulnerabilities to initially infect systems and to spread the virus. The vast majority of viruses target systems running Microsoft Windows, employing a variety of mechanisms to infect new hosts,and often using complex anti-detection/stealth strategies to evade antivirus software.
