What to do if a rootkit is detected?

I ran chkrootkit and in the output that the process generated I found this entry:

Checking `bindshell'... INFECTED (PORTS: 465)

So.......what does one do? What is this?

chkrootkit is "over agressive" in that it will report anything it thinks is remotely dodgy. In other words, it very very very very very often reports false positives, so don't be too alarmed. That said, you should investigate what is listening on your ports in general. `netstat -pants` will give you clues (and other permutations of `netstat`)

Hi Guys,
I think this is resolved. I did some Google Searching and found that "exim" can cause a false positive. I checked and found I had installed exim. It has something to do with email. I mainly use Yahoo WEB mail, and Thunderbird with another POP3 account.

I removed exim, and re-ran the rootkit check. This time it came up clean.

I guess this was a false positive. Thanks for helping out. I'm glad I am still clean.
