Bad news it will become more vulnerable as from the 8th of April 2014, because Microsoft will no longer be issuing free updates or security patches for Windows XP.
Question: Yeah but it's fine now, why will that change after the 8th of April?
It has been very well publicised that support for XP will be ending, those wishing to target XP computers are well aware of this and among other way can reverse engineer the updates or security patches for current operating systems such as windows 7 and 8 to help them expose weaknesses in previous versions. And if you wanted to get a computer to do something that it shouldn't you would probably hang fire until it was no longer protected properly.
Question: What can I do?
BACK UP ALL YOUR FILES!!! There are many ways to back up, you could back up to the cloud, or by way of an external hard drive or if you have no other option burn to DVDs. This is generally considered to be good advice anyway, but at least you will know you have the files important to you.
Question: What else can I do? You could buy a new computer. Some good deals are available here: Ebuyer >
You may be able to upgrade your operating system, this will depend on the spec of your computer. Please see Windows tutorial for more info, or have a chat with File Genie >
Change over to a Linux operating system. Please see here for more info: Move from Windows to Linux >
Question: I have an antivirus, will that protect my PC? Most anti-virus software makers will support Windows XP for 12 months or more. As mentioned earlier, this is not the full story and some paid antivirus programs may be not too far away from the price of a full Windows upgrade.
After nearly 13 years of Windows XP, for me is it is a bit like saying good bye to a trusted friend. However despite the bad press of some of the latest Windows versions, they are really not that bad and in many ways much better. Happy computing!
