How do I view net pages through one of  those portals which doesn’t
register the actual addresses you view e.g. by always having Google in
the title bar? Is there a way of having your cover blown on a work
computer?

Hi there,

What you need is a proxy server. There have been many over the years,
and they typically don't last very long. Anonymizer is the best:

Anonymizer 
http://www.anonymizer.com/

"Thousands of people have lost their jobs because they weren't careful
about where they surf at work.  Even more of us are unwittingly
providing our ISPs with intimate personal details through our web
surfing, which they can turn around and share or sell with anyone.

The Anonymizer I.D. Protection Suite provides two layers of encryption
protection (SSL Encryption and URL Encryption) to shield your Web
activity from your boss, co-workers, ISP or other untrusted network."
