Extended information:
As long as any virus enters the system, it will have varying degrees of impact on the system and applications. At worst, it will reduce the computer's work efficiency and occupy system resources; at worst, it will cause data loss and system crash.
The program of a computer virus is meant to be an executable program, just like any other legitimate program. However, not a complete program, but a program that is parasitic on other executable programs. Viruses can only destroy other programs when they are running. Once the virus enters the computer and is executed, it will search for other matching conditions, identify the target, and then transform into it to achieve the purpose of replication. Therefore, infectivity is an important condition for judging computer viruses.
