Probably the most notorious was an attack on Spotify, which led to people being infected with a virus as soon as the advert was displayed on screen. This is known as malvertising and some very high-profile sites have been used to host attacks. Basically, cybercriminals are buying advertising space on legitimate websites and placing adverts which aim to trick users into clicking on links to malicious websites. These days, they are a serious, and growing, security threat. In the early days of the internet, adverts were a minor inconvenience people generally tolerated because they subsidized a lot of content creation. The best free antivirus programs have integrated ad blockers In fact, there may come a point where they get so large that it is impossible to host them locally on all but the most powerful computers. This is already a significant benefit and it’s probably a safe bet that databases of malware definitions are only going to get bigger and bigger as time passes. Everyone has had the experience of being absolutely sure that they did something only to discover that they hadn’t and if that something is to update your antivirus program then the results could be, literally, life-shattering.Īdditionally, it reduces the burden on the host computer. It eliminates the possibility of user error. This approach has another couple of advantages. This is the main reason why the best cybersecurity companies are now hosting free antivirus products in the cloud rather than sticking to the old system of creating updates which users would then download and apply to their local computer. Picking up from the above points, the quicker these updates take effect, the quicker you will be protected. The best free antivirus products will be hosted in the cloud Because of this, cybersecurity companies have to keep updating their databases of definitions so that their products remain effective against the latest threats. Ransomware, for example, is a relatively new invention and its use is growing at an alarming rate. Malware creators are constantly producing new variations of old threats, such as viruses, and periodically coming up with totally new forms of threat. These are basically descriptions of malware, along with instructions as to what to do about them. Basically you need to avoid it at all costs and since you can avoid it for free, it makes complete sense to do so.Ī free antivirus is only as good as its updatesĪll antivirus programs rely on databases of “definitions”. Spyware can steal anything from your banking details to your whole identity. It’s important to have solid protection against all of these threats, especially spyware which is designed to be virtually impossible for humans to detect on their own. It’s also an odds on bet that more forms of malware will be created in future as cybercriminals keep trying to think up new ways to get past security software. Now there are multiple forms of malware including spyware, adware, lockware and ransomware. It’s been many, many years since viruses were the only form of malicious software in existence. “Antivirus” is one of those terms everyone uses, even IT professionals, although it’s long since gone out of date.
