Short answer: no
Long answer: you always have to keep up with any device and protect it from any infection
The young man who paralyzed the global cyber attack with the WannaCry virus, already has a name: Marcus Hutchins
The WannaCry virus is behind one of the most widespread cyber attacks in history, affecting more than 170 countries and caught many big companies by surprise. Ironically, all this could have been avoided if their computers had been up to date with Windows updates, but that is another matter. Now that it has been clarified what has happened, that the virus has been paralyzed to some extent in most infected countries And that it is better known how it acts, the time has come to ask certain questions facing the basic user, that is, the vast majority of us.
Is the computer at my house dangerous? There are two ways to think about this. Are you at risk of being infected by the virus WannaCry that has taken the colors to Telefónica, Renault and many other global companies? No, surely not. Unless you are a worker who has used your computer to connect to the internal networks of one of these companies, it is very difficult for this variant of the WannaCrypt ransomware to reach your device. Now, is the computer at home, So in general? Yes, of course, like any device that connects to the Internet. It is what technological news has: if you do not care and click on suspicious links, the antivirus is not updated and Windows, MacOS or Linux is not updated regularly, sooner or later some virus will cause you a bad drink.
What can I do about it? Just the latter: have an antivirus installed, update the operating system of your system and be wary of where you click when surfing the Internet. This is like buying a car: there are many brands with many functions and many extras, but in the end, they serve the same purpose: protect your computer from external threats. If you do not want to complicate your life, peace of mind: Windows 10 has a fairly competent antivirus installed, Windows Defender, and works quite well. It comes bundled with the operating system, so it’s free and does not ask you to do much more. With MacOS, more of the same: Apple knows how to protect their computers without needing an antivirus to use. There are many other brands and companies with antivirus: Norton, Avast, Kaspersky, Panda … Some of these programs come installed with certain computers of certain brands, but in most cases, you have to either pay for premium versions or use free versions Which protect what is just and necessary.
Again, the case is to have one and have it updated. Another thing is that, in exchange for protecting you, its operation is effective, do not consume many resources on the computer and do not overstress your day to day. Quid pro quo … And what about the updates? That your thing is that you say yes to everything. Okay, maybe in a few cases, Microsoft or Apple will spoil it with an update and it will not go as fine as it should, but this is usually an exception. Generally, accepting all updates is the least you should do if you want to have your computer protected. It is becoming more difficult to know what each update brings or opt for yes and no. Not all versions of Windows allow you to do so and MacOS, generally, does not allow this type of control over the computer. Even so, there are not enough reasons to refuse to upgrade for fear of the new. The same with Android or iOS: update is always the best decision, although if you really worry that the new version can spoil your mobile, that’s Internet. To be aware of these things, it is sometimes as simple as searching for the reference of the update that has come to you and put it on Google along with the model of your phone or your device. It is of no use to have an antivirus or be careful if Windows has a major error and you do not bother to update when the computer asks for it.
How can I know that a link has a virus? Sometimes, it is obvious: if a web that You do not remember to have opened and that has appeared of the nothing in a new window after clicking on a link or an advertisement of another web asks you to download something, surely you should not download anything of what you ask for. Staying away from pornographic websites (not all, but most), illegal downloads or streaming that are unofficial or have a certain reputation is not a bad idea: advertisements of many of them often hide intentions that have little or nothing to do With what they announce, however suggestive it is. Similarly, if you get an email that does not seem very normal, be very careful with any attachment you have. The same with emails from banks, telemarketers and other big companies that you do not expect. It could be advertising.
What other ways can I get a virus? Like everything in life, you have to know where you plug your computer and what you plug into it. That WiFi network so opportunely open may not have as good intentions as you think. It is very easy to hijack information when a computer has been connected to an unsecured network, even if the network itself is not designed for it. So be careful with connecting to any WiFi. On the other hand, the same with the pendrives. Did you know that the Russian spies sneaked into certain US embassies through USB flash drives that the employees of the above-mentioned shop bought at a nearby computer store? Be careful with the USB stick if you do not know for sure where they come from. If you find yourself in a cafeteria or are in a corner, be careful: would you wear a coat that is lying in the middle of the street, however free it may be? Once in a while, maybe every week. This is a task that computers, especially Macs, can do only and without demanding much of the computer. They can also be configured to be done when you are not using the computer. There are plenty of programs to do this in Windows without going through the box, but the system itself has ways to do it on its own if you have the latest version, Windows 10. In either case, you need an external hard drive Some capacity and durability, because files are being copied constantly and outside the computer. But if you keep up-to-date backups and you get a very aggressive virus, you can always restore a version of your computer with a day or two of antiquity and get rid of almost a disgust.
