Q: I bought a new computer about six months ago, and it came with a trial version of Norton Internet Security for 90 days and Windows 7 installed.  I was planning on renewing this subscription, but hadn’t gotten around to it.  The other day when I switched on my computer a message saying I was infected with a Trojan came up, but it says Windows Antivirus 2011 – not Norton.  My friend came over to help me get rid of it, and he put AVG Free on my computer for me.  Now I can’t do anything, my computer is painfully slow, and I still get the message about the Trojan.  What should I do???
Internet security is extremely important, especially if you shop online with your credit card, use Internet banking, or send emails and files to friends and family.  Before installing a new anti-virus program, it is important to uninstall your old one, even if your subscription has expired.  Failing to remove your existing security application will result in the two applications conflicting with each other, and this will have a huge effect on your system’s performance.  The message telling you that you have a Trojan is actually a virus itself.  This sort of virus is very common; it is designed to look like an anti-virus to trick you into giving your credit card details.  The virus will also attempt to disable your anti-virus leaving you vulnerable to any number of security threats from the Internet.  As removing a virus can be quite tricky, and there is a risk of data loss, we recommend having a computer technician complete the work for you.  The technician can also ensure you have one complete Internet Security application that is up to date and protecting your computer.
Q: Is there a way to keep track of how much time we have spent on the Internet each month?  We always seem to run out near the end of the month, and then we have to put up with Internet that is so slow it’s almost not worth using it.  This is very frustrating!!!
Using up all your allowance on the Internet before the end of the month can feel like you have been cut off from the rest of the world, luckily there are many ways you can keep track of your usage as you go.  These days we measure Internet usage by the amount of data you are downloading and uploading, not by the length of time you are online.  Things like watching YouTube, chatting on Skype, playing online PlayStation or XBox games will use a lot more data than just surfing the Internet.  
There is a program called TUC (Traffic Usage Checker) made especially for Internet users in New Zealand.  TUC will log into your Internet Service Provider’s site and report back with how much data you have used.  This program can be downloaded from here: All you need to do is enter your username and password from your ISP, contact them if you are ensure of these details.  
If you are looking for a more comprehensive analysis of your usage you may want to consider purchasing a Webgauge router.  This device will track all your Internet traffic, display your usage for each individual computer or device on the network, and even split the bill for you!  This is especially beneficial in a flat where the Internet bill is shared between flat members.  Visit their website for more information:
Q: I thought I was ready to make the swap from PC to Mac, so I went out and got myself a shiny new iMac last year.  The technician who set it up for me transferred all of my data across, and set up Windows to run on a separate part of the hard drive.  I was thrilled that I could make the change at my own pace, and use Windows when I wanted to, and Mac when I wanted to.  Since then I have never logged in to the Mac side of the hard drive.  I have even forgotten how to do this!  Can you remind me how to choose to log in to the Mac so I can at least give it a chance?
Boot Camp is a great feature of Mac OSX that enables you to install Windows onto a partition of the hard drive.  You can set either Mac OSX or Windows to be the default operating system that your computer will boot from each time it boots.  If you want to leave Windows as the default, but would like to try Mac OSX occasionally, then you can hold down the alt/option key as you switch your computer on.  This will display an option to boot from either Mac OSX or Windows, and will even give you the option to boot from a CD if there is one present.
If you want to change the default operating system then boot into Mac OSX, and then click on the Apple in the top left corner, then select System Preferences, and click on Startup Disk.  From here you can choose between Mac OSX and Windows.

Review: Lenmar Meridian iPhone Power Case

NetGuide The iPhone is known for not having the longest battery life. Too often you see people carrying their charger with them as the phone won’t make it through the day (and that’s without calling!). Battery cases have been around for a while, but what makes them better than just carrying the plug?   Read More →
