space sucker 4000

Hi, people who are smarter than me!(everyone)

TL;DR version
Are there any good programs that can show files that are being added to my computer, maliciously or not?

My computer seems to reach critically low disk space often. Every time I make space it seems to be filled up rather fast, but I don't beleive I am the one adding the files.

Oh, and the thing that can show files being added to your computer is called a firewall.
You're a fucking idiot.

If it is infected, these checks won't be effective because malware has its ways of hiding from the scanners if they're running.
Most malware doesn't. There wouldn't be any malware scanners otherwise, now would there?
