Why Remove spyware/malware tools?

I have been reading through the spyware/malware removal forum and noticed that once the threat(s) are removed and the system appears to be clean, you are told to uninstall HJthis, ComboFix etc.. What is the reason for this?

Also, when told to download the various tools, everything goes to the Desktop. Is there a technical reason for this or is it just to make it easier to find the stuff you download?

I gotta say, this is the most helpful technical forum I have come across in years. The amount of work and time the moderators put in here is unbelievable!!

Thanks,

The tools you are referring to are very specialized tools, they are not ordinary security programs. Just as a doctor wouldn't keep sponges and clamps in a body once surgery is over, just so the team has these specialized tools removed. They have their place, but once they have served their function, they need to be removed.

A technical reason? To slow down the screen display/refresh

Seriously, IMO best place is a folder called HJT or AntiSpyware or whatever. But I think most users can't make one, nor direct a file to it, nor scan it before use. The way Windows is presented, with no Windows Explorer in sight, and no hints of directories, it's just not feasible. So the desktop, messy and ugly as it is, is the best fallback position.

Think of a user who downloaded a trojan and needs to learn how to cleanup. LAST thing on their mind is to learn how to use Windows properly. They have enough on their mind to read the superb BC instructions and wade through the mess. So, that's my take on the subject.

OK. Thanks for the replies. Just curious.

Nice analogy ~ OB.

Also.....

Without getting into the details....
The steps for "uninstalling" specific security apps does more than simply uninstall the app!! It is a critical step in preventing reinfection.

Again....

Most of these tools should be used only under the direction of trained personnel. Unsupervised use can result in the inability to boot your OS...ever!
