Email bomb

[just4sky]

I found that few hours ago there is an anonymous php file appear in my public_html/v2/learn/ and it is email bomb (I think). Then, my hotmail starting receive uncountable emails from my hosting. I deleted the php file but I still receive those emails. What can I do to solve it?

1. Shutdown your mail server process and suspend or change
the password for that hosting account

2. Check out your maillogs and flush mail queues if necessary

3. Check your other system and account logs and take a close look at the
scripts in the hosting account in question because sounds like there is
definitely a compromised security issue and you need to know where those
files came from and how they got there and then close down the issue
so that it doesn't happen again to you.
