5 Tips to Easy Keep Your PC Clean

Don’t share any folder (but read only), but still the best way is not sharing it at all.
Don’t open any attachment from stranger or someone you know will never send you a hot britney spears video
Don’t install-unsintall-install-uninstall many programs. Too much love will kill you, I mean too much install-uninstall will kill your windows registry. For every program you installed there are registries written and most expert knows, when it uninstalled the registry key remains. Invalid registry key can lead you to “illegal operation” or “not enough memory” (although when you check, you are still using 4MB of your 1GB RAM) error message.
Don’t follow link to suspicious web site. Usually this will lead you to a site contains virus or trojan. Eh, have no idea what “trojan” is? Err… ask uncle wiki will you?
Don’t mess up your pc. I mean, use the “Add/Remove Program” feature to uninstall a program. Delete it via Windows Explorer is absolutely the path to the dark side. According to it, delete or rename system file or folder will of course take you further to the dark side and not even Yoda can save you.

Clean your PC is so easy, isn’t it?
