Is it possible write a virus program in c#, if it is, can any one give me an example
Treading into dangerous territory with this question, but a proof-of-concept virus-like program has already been written in C#. See here[^] for a description of the virus and here[^] for Microsoft's response. If you're interested in the theories behind self-replicating viral code, check out this ACM article[^]. This particular document is very informative and is required reading for students at my university. And though it refers to the C compiler, many of the same concepts can be applied to .NET languages. -- modified at 22:53 Thursday 4th January, 2007

It's possible to write anything you like. The question is, why would you want to ?

Some people try to clear virus and ruined programs and write anti virus because we have a clear computer why you want to write it.

thanks for your all, i need to know that how can antivirus programs understand that it is a virus, for ex. if i write a .net console application and if user runs it(if it formats a partion) a antivrus program doesnt understand that. I wish to explain what i need to know, thanks again Best Regards

Cool score of 1 :-) Does that mean, that there are questions which shouldn't be asked? That would be very strange!

http://en.wikipedia.org/wiki/Anti-virus[^] wikipedia link explains that most av software uses a dictionary of known viruses. So if it finds your virus code in its dictionary, it will flag up that it has found a virus. The EICAR test virus is an example used to ensure that av software is working correctly (using the dictionary method)
X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
The above code is the virus sig of the EICAR virus. Copy it into a notepad and call save it as test.com (not test.com.txt!) and you av sw should detect it.

The wikipedia entry also explains how av software detects suspicious activity (and so does windows vista these days) - this allows the av software to detect things that might be viruses (e.g. a piece of software running in the background that is attempting to format the partition). You'll have to check your av software to find out if it does this. I hope that helps with a bit of background. I won't wish you luck writing your virus in c#, though.

i need to know background programming, how can a process run in background and, it doesnt need click to run
You would typically write it as a Windows Service (assuming that it's the AV that you are talking about here).
the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
