Hello and welcome to the forum!
This is in the Windows 98 forum so I will assume that OS.
There are very few programs left that work with 98 and I know of none that actually work in true DOS mode.
MalwareBytes and SuperAntiSpyware are XP or greater. I believe Spybot Search and Destroy still works with 98.
"Removing all form of threats like virus, spyware, adware etc."
There is actually no single tool that will do this.
In the beginning there was the command line.
