We all saw at least once this message on our screens: “You have been infected! Download antivirus X right now to protect your computer!”
Many of these pop-ups were very well created to look like legitimate messages that you might get from Windows or any other security product.
If you are lucky, there is nothing more than an innocent hoax that will bother you by displaying unwanted pop-ups on your screen while you browse online. In this case, to get rid of the annoying pop-ups, we recommend scanning your system using a good antivirus product.
If you are not so lucky, your system can end up getting infected with malware, such as a Trojan or a keylogger. This kind of message could also come from one of the most dangerous ransomware threats around, such as CryptoLocker, which is capable of blocking and encrypting your operating system and requesting you a sum of money in exchange for the decryption key.
Also, make sure you do not click on pop-up windows that annoyingly warn you’ve been infected with virus. Remember to always apply the existing updates for your software products, and install only legitimate software programs from verified websites.
If you’ve been infected, you can use an antimalware tool such as Malwarebytes to try removing the malware infection or pay attention to these warning signs and learn how to find a doable solution.
