Everyone knows that computers are the most influential piece of equipment for both the office and home to come around since the ball point pen. An office environment has the benefit of having either a managed services or outsourcing company or onsite technical expert and expertise to protect their data but a home computer doesn’t. The technical support usually comes from mum or dad or from the teenager. This can be disastrous especially if the computer is used for other purposes like internet banking, internet purchases or keeping confidential personal data safe.
Most of the time the protection for a home computer is the installation of an antivirus software package and then the whole thing is forgotten in the euphoria of accessing the internet, doing the “Facebook thing” and playing games either on line or against the computer. Don’t get me wrong I “LUV” playing games on my computer but I believe that I have a relatively secure laptop most of the time, but I have the luxury of having a little training and experience behind me.
So what can YOU do to protect not only your computer but also your personal data and your internet banking? These are 3 of the most basic things that you can do in the never ending process of keeping yourself secure:
AntiVirus: There is no excuse for not having some level of antivirus installed on your computer. There are a number of freely available packages – Security Essentials (Microsoft), Avast or Avira, that will stop most viruses in the wild but there are times where they will not pick up viruses that have not been discovered. A more secure antivirus that does a lot more will have to be purchased. If you are looking to purchase one of these packages then you should be looking at Kaspersky, Norton (Symantec), Trend or the like. These packages do a lot more than just track your antivirus. They will protect your computer from Malware (Scripts being run from a website), I had this experience just the other day when I was doing some research and went to a website that wanted to infect my computer. My antivirus protected me. Most of them also have a decent Anti-SPAM component as well as a fairly substantial firewall. I can hear you from here – I have a MAC and it never gets a virus. Sorry that is no longer true. Some malware will infect a MAC and they are very painful to remove.
Firewall: By having a firewall installed at all times especially when you are surfing the internet is not only a necessity but it can honestly save your wealth. They can at times be problematic with false positives (incorrect readings) but as a first line of defence they are indispensable. Although most firewalls are set and forget, if they detect something wrong they will pop up a warning – Please read it – so that you can make a decision on letting something in or not. Again there are free variants available but good ones come packaged with the antivirus.
Update: I cannot say this often enough update as often as possible and don’t put it off unless there is a good reason. The update process is designed to patch holes in operating system software as well as application of all types. A hole in software is where the virus writers target their programs because they know that people are lazy and don’t like to update their computers and even worse restart their computers after the update process. All of the big software companies, including game writers, now have an update process and after you install an application it will check the website through the application or every time that you open it.
As an additional point if you are running Peer 2 Peer software on your computer, normally installed by the teenager to download music and movies for free, then I suggest that you remove it. Peer 2 Peer software is designed to punch holes through firewall and disable antivirus so that they can be seen on the internet. Peer 2 Peer software works on the principle that there are numerous sources or copies of the wanted download that you want. The problem is that the available directories can be used by outside people to store child porn, pornography or pirated movies and music that you may not even know about.
So there you have it. Home computer security is mostly common sense and thinking ahead. These 3 points will ensure that your computer is well on its way to being protected when you use it.
