Guide To PC Security
If you have a computer in your home that is connected to the internet then it can be a portal to a world of entertainment, information and education that dwarfs anything that was available in previous generations of human history. However, it is also potentially a conduit for some seriously harmful software, because criminals are constantly looking to exploit the unassuming, average internet user with viruses, malware and spyware that can at best make your PC run slow and at worse leave you defrauded and in need of legal assistance. This is why PC security is so important and why there are software vendors making billions of pounds from protecting individuals and businesses from the malevolent people out there in cyberspace. See the simple steps below, put together by FreeTrials.co.uk, to help you stay safe online.
The first line of defence in PC security should be a firewall. You will usually be accessing the internet via a router or modem of some kind and if you have broadband it is safe to assume that there will be a firewall of some kind built into the router itself. This is good news, because it means the most basic attacks will be deflected with ease. However, if you have a wireless router and a Wi-Fi network established in your home, you could leave your broadband connection and your PCs open to any passerby with a Wi-Fi enabled device. For this reason you need to ensure that you encrypt your Wi-Fi network using the provided security tools which the router’s manufacturer will allow you to activate. You can choose a passphrase or generate a pre-shared key so that only the devices which you own can gain access to your web connection and your home network.
To keep your PC safe from viruses and malicious software which can be unknowingly downloaded from seemingly legitimate websites or from email attachments it is worth investing in some form of PC security software suite. You can purchase individual components of a more comprehensive software suite, but it is always sensible to go for the full blown package if you can and if you want to make sure that you are as safe as possible when you venture online. Typically you will need software that provides antivirus, antispyware and firewall protection and in most cases you will find that vendors combine all three into a simple package.
Antivirus and antispyware protection is essential because these types of malicious programmes can steal personal data. In the best case scenario this will just keep track of the websites you visit and then send you adverts based on your favourite products or hobbies. This is an invasion of privacy, but it is a minor annoyance to the more serious assaults that can be brought down by more complex, dangerous viruses. You can have bank details, login names and passwords swiped from your PC, allowing hackers to access your email, social networking and online banking profiles and cause all sorts of costly mischief. Proper PC security software will neutralise this kind of software at its source, either by detecting it as soon as it arrives on your PC or by identifying the websites which are most likely to carry it and directing you to use them at your own risk.
If you do not want to commit to a PC security software suite without having a bit more time to get to grips with it, then most vendors allow you to trial their software for a limited time, for example see the latest McAfee Free Trial or Norton Free Trial. Alternatively there are some who offer free, cut-down versions of their full package that give you a taste of what is on offer without requiring a payment unless you want to upgrade.
