I don't know if this is a repost or not but I know this is very helpful. You go to the website, post your HiJackThis log and the website **automatically** analyzes your log and tells you which entries are "nasty" or not. Here's a short site description:
" Until now, inexperienced users, who could not analyze the log file by themselves, had no other choice than posting it in a specialized forum and to hope that a more experienced user takes some time to analyze it. The script presented on this page is a way to analyze your log without help from the outside: simply copy/paste the content of the log file in the textbox below and hit the analyze button. "
