Hello Student,
Virus is an infectious agent that doesnt replicate by itself but divides only in living plant, animal or bacterial cells. Virus particle consists of i) genetic material DNA or RNA ii) protein coat and iii) envelope of lipids that surround protein coat.
But there is nothing called previrus...So please crosscheck if it is some other term.
Regards
