Answer / vignesh1988i
virus are a set of programs which infects a system
(computer) and slows down it's efficiency.... all will have
virus... internet , DVD ,pen drives ,etc etc ... but
viruses are orginating from internet only. so when the
virus enters the system it will affect the microprocessor
and since it will act as an interrupt , this will be given
high prority. so the microprocessor will start functioning
as per the programs and so only our task will get
delayed.... so our system will not fuction according to our
OS programs... thus it affects the system performance

Virus may infect the system through Internet,Floopies,Usb
drives, Cds, DVDs, and other portable devices. Virus is like
a mini program which spread to steal the data from one
computer to another and slowdown the performance or some
time rename the particular files to another. These will be
prevented by purchasing the Antivirus software and update it
on regular basis and run full scan on safe mode. these are
few examples.

all memory space (PC freezes, slows down, low performance ,
system restarts automatically).

next time or windows files deleted/ corrupted)
3. It changes right access permissions effecting ( task
manager, hidden files, right access options etc)

Answer / 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.
