Heh, this reminds me of my ~10 year old self. I had unknowingly infected my family PC with some form of malware, but no knowledge of AV software.
I guessed, incorrectly, that perhaps the OS developers would have been smart enough to disallow users from deleting OS owned/managed files. So I went around finding and deleting everything that looked remotely official, including C:\Windows\System32. To my surprise, it worked.
Until I rebooted :(
