Help! Cloudmark somehow got into my computer and is blocking e-mail

I’ve never even heard of Cloudmark and I’m sure I didn’t download anything. E-mail was working fine this morning.

I deleted from the computer and restarted the computer, but its still there blocking all the e-mail. I know for a fact that several e-mail didn’t get through.

I use outlook express.

How can I really get rid of it? Their website is worthless.

Thanks!
