how does a virus infect the system
Answer Posted / chakrapani boyina
The virus comes from internet browsing. Some popups
automaticaly downloads virus programs when there is no
specific security to the systems. mostly virus comes /
effects to internet games, screen savers, wall papers and
to some automated programs. This virus mainly effects to
*.exe files and also to win32 files. Because of this system
access becomes slow. When such systems are working in lan
there is a chance of genetation of virus to all network
systems. Because of this virus there is a chance of loosing
data also. Also virus transfers from one system to another
because of using virus effected removable disks such as
dvd, cd, pendrives, dat drives, floppy drives.
