1) take if off the network.
2) burn a rescue CD and boot the machine with it. I suggest ubcd4win -

any other plugins (malwarebytes, especially) you deem appropriate to
see if you can clean/identify the culprit. I just tried ubcd4win
yesterday, and it was dead easy to work with. Excellent tool. There
are other good tools, but I just used this one and like it.
3) regardless of whether you clean the machine and/or identify the
culprit, save the data, rebuild the box and patch it so that it
doesn't get infected again.
Personally, I don't like McAfee at all. We switched away from that to
the Sunbelt product, and haven't looked back.
Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate. We look at how SSL works, how it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
