Re: Zombie / Botnet?

Thanks to everyone who replied.  Anyway - the workstation was in a
different building.  I had our helpdesk take a look at it and I've
escalated the packet trace (tcpdump) to our AV vendor.

I'll keep you updated on what happened on this.


Thanks once again.


Best,
Tony

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.
