____________ deletes all the files that it infects.

A. Non-resident virus

B. Overwrite Virus

C. Polymorphic Virus

D. Multipartite Virus

I had been asked this question in class test.

This key question is from Attack Vectors topic in section Understanding Attack Vectors of Cyber Security

Right choice is B. Overwrite Virus

The best I can explain: Overwrite virus deletes all files that it infects. It can be removed by only deleting those infected files. Mostly, it gets spread via emails.
