wht exactly want is how to remove manually virus(unwanted programs) manually by ms dos i use to do that through attrib but not exactly to do so to all of them so is there any way by which i may delete all or can say almost all of the virus through dos...
You need to know the file names and paths to delete them.
However, some files are locked because of the malware infection, in which case we have to go for kernel level deletion.
This is not possible in command prompt.
Some of the files you have attempted to delete fit the above criteria.
Try this :
attrib -R -S -H filename.ext
and press enter.
This may not work if the file is locked, in which case we may have to use special tools.
As you can see in this post, the user cannot delete the file, because "It is in use by another application".
But when you look at the running processes, you see that it's not running in the background.
This is a perfect example of a locked file.
