Does it have a right-click shell extension to scan files?

A shell extension is a small system utility which gives users the ability to manipulate the settings of the PC through the operating system.

Often, one of the features overlooked by antivirus protection is the usability requirement of quickly double checking a file before using it. Many antivirus programs only automatically search certain file types based on their extensions, so look for a shell extension that forces a scanner window to open and immediately scan any file selected as opposed to one that just launches the scanner interface.

Does it make boot disks and/or have a CD-ROM that can be used for cleaning an infected PC?

Boot disks are required to recover from a nasty boot sector virus, and having the scanner on a CD-ROM means it should be a snap to repair even an infected PC that doesn't have an antivirus program installed.

Product Activation. What is it? And how does it affect me?

Product Activation is a process where a user or application contacts the manufacturer (usually via the Internet, but it can be by phone or fax). It lets the software vendor know some information about the application running and to provide a response that may trigger a change in the application. In the case of antivirus programs this is important as the software activation will signal the beginning of the time cycle for free updates.

I stongly recommend not to buy Norton Antivirus2010, I have had two serious viruses in one month. And forget the free 24/7 customer service, infact forget any customer service! You will past onto a Yogi technician in India, usually they cannot speak coherent English!
They will mess around with your computer for a bout three hours and try to charge you$139 to have a microsoft technician fix the problem. My computer was still under guarantee, so thankfully I had the presence of mind to tell them to get lost!
Hewlett Packard Helped but once again there is that fast speaking Indian Accent problem. Why do these corporations pay fortotally substandard help desk personnel in other countries? It is an insult to their customers!



Often one standalone program is not enough and many experts recommend a teired approach to malware.

I use and recommend Norton Internet Security 2010 and Counterspy. I have never had a problem with malware.
These programs offer top shelf protection. Kaspersky also is good at detecting malware but not my preferred choice.

There were some complaints regarding Norton in the past but the program has matured in recent years and is now one of the best programs available offering solid defence against internet threats. Norton also uses minimal recourses.

I am online almost 24/7 and game, chat, research and shop and never have any issues relating to malware.
I run a second on demand scanner from time to time to check
that my system is clean. And have not found any infections.
Friends that I have recommended Norton to have also been very happy with Norton Internet Security and there systems remain clean and funtioning properly.

Norton is now a great product and highly recommended.



I like Ur Briefing about Virus.
But I don't know that in which way i clear my PC from Virus.
I installed Antivrus.But no working.



id just like to say that working in IT... i think you guys need to understand that a good anti v program will tell you you have viruses. a useless one will say you've got none. 9 times outta 10 theyre lying or don't detect it... if u are regularly being told uv git a virus uv got a good anti virus.... guarenteed plug ur "infection free hdd" upto a norton internet security protected pc... norton will find somethin ur av has missed

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

Steph Mundell


The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

Simon Harriott


My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
