questions about computer virus

[SRSRAJA]

respected sir;
i have a doubt about computer viruses,that is;
for eg consider:
my system has a lot of viruses.
the doubt is ,if i insert a disk or a pen drive which has full of details, that is it has no empty space ,then it wil also be affected by the virus.how it is possible.

i studied in a book that a virus is a self replicating proigram,it occupies some space or thefts some memory.if the disk has no space then how the disk or pendrive will be affected by the virus."BUT THE TRUTH IS THE DEVICE WILL BE AFECTED BY THE VIRUS".

I NEED TH REPLAY, SIR;

Well, he didn't say he wanted to create one, he was just curiously asking. Well my friend. Most computer viruses have the ability to replicate, because without replication their whole lifecycle would be ruled out just the way humans replicate to prevent extinction. Well some viruses like the one I was working on can copy them selves into other programs, or rather copy their code into a virus free program, so you don't know it is a virus but you think that it's a program you know and have Been using for long. Consider cmd and explorer for instance. They are one of the most used programs on windows. I hope you get the point?
