Can we identify any viruses, malware, spyware...........etc., without using any antivirus softwares that are running in our system...... ( may be hidden processes).

If so, How can we do this ?

wihtout any anti - viruses program .

My job Virus Remover .....

its depend on Computer Status ......

I mean every status need another way or over

Can you provide me with an example ?
With a neat explanation......plz
also provide a virus file ( should not do any harm to my computer) to test

I really don't think that's possible.

There's also no way you could do it faster than a virus scanner, if you are looking for something specific then I would suggest asking EvilFantasy.

<edit>  I'm going out on a limb and calling doctor hack a liar.  If he could do it then it certainly doesn't explain this thread.

Atleast any dos/C/C++/VB/Java programs.........atleast

for removing autorun virus......
