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.
