If you're just cleaning out junk files, here's a great program that will take care of that for you.
www.ccleaner.com
It takes care of the usual places- cookies, temporary files, recycle bin- and other, more discrete places as well. To top it off, it will clean up your registry and help with programs on
startup and removing programs.
If you're suspicious of any leftover files or folders, you may want to run some virus/malware scans.
I recommend A-squared Free, Avast! antivirus, and AVG Antispyware if you want to download programs.

Respectively.
If you want a less space-taking solution, you may try some free online scans. I recommend Trendmicro Housecall, Kaspersky, and Windows Safety Scanner, but you may pick as you like:
