All of us should be using a good quality anti virus on all of our devices to try and ensure that we are protected when going online. There are millions of different anti virus software companies that you can buy from and finding which one is the best can be tricky.
One of the first decisions you need to make when choosing an antivirus product is whether you want to spend any money or not. There are a few good antivirus packages that do not cost anything so there really is no excuse not to have one on your device. Compare the packages to that of the paid for ones to see what you get extra, it may be things such as cover for your email and plug in devices etc.
Free antivirus products usually have the same antivirus detection features commercial antivirus products do, so they’ll detect and block malware just as well.
