VBS/Malnir-A is a Visual Basic Script worm.
VBS/Malnir-A attempts to copy itself to the System folder and to all drives with the filename autorun.vbs, deleting all files autorun.* from these locations and and copying the files autorun.* from its own folder there instead.
If VBS/Malnir-A finds a file named autorun.vbs that is not a copy of itself, it displays a message stating "Virus Found and Deleted in drive <drive letter>" in a message box with a title starting "Nirmal's Antivirus system".
