Could this be done shorter/neater

I yanked a script from Git-Hub to install 7-Zip with Powershelland pieced the rest as I was learning it. It's simple and more for learning than anything else.

Here's what the total of the script does:

1. Creates a cleanup folder under C:\ (If it doesn't already exist)
2. Installs 7-Zip (If not done already)
3. Downloads virus/malware cleanup tools. (ADWCleaner, Combofix, Junkware Removal Tool, MBAM, and CCleaner.)
4. Zips them into a package to copy through a Remote Control software such as Teamviewer.

It would also silently run them but they don't have the switches for that.
