Have you heard of those viruses that lock your files and demand money to restore them? Well, UIWIX is the name of the newest member of their family. UIWIX is a classic ransomware. It uses trickery to slither into its victims’ computers. Of course, it won’t betray its cover until it is too late. UIWIX works in the background. The ransomware won’t waste time. It will start working at the moment it is installed. Its first step will be to scan your HDD and detect all target files. UIWIX can encrypt over ninety types of files, including documents, pictures, and archives. It adds the “.UIWIX” suffix at the end of all encrypted files. Thus, if you have a file named example.exe, the virus will rename it to example.exe.UIWIX. You will be able to see the icons of your files, yet, you can’t open or use them. Luckily, UIWIX doesn’t encrypt files that are essential for your OS. At least, you can use your computer to look for a solution. The bad news is, there is no free decryption tool, yet. However, security researchers are working on it. Therefore, don’t rush. Don’t contact the cooks. And most importantly, don’t pay the ransom. The hackers behind UIWIX demand 0.12 Bitcoins (about 220USD). In exchange, they will send you a description tool. Hackers have chosen this currency because it is impossible to be tracked down. Even the authorities won’t be able to help you if you don’t receive the decryption app. Don’t pay the ransom! You are dealing with criminals. You can’t expect them to play fair. They will double-cross you.

How did I get infected with?

There are many possible ways for UIWIX to reach your PC. Of course, spam emails are the most commonly used distribution technique. How many times have you heard not to open emails from strangers? Stop doing it already. Scammers are clever and imaginative. They will embed malicious code into all sorts of files. Before you download an attached file, check the sender’s contacts. Do so by entering the questionable email address into some search engine. If it was used for shady business, there might be evidence online. Don’t stop here. As we’ve already said, crooks are creative. New email accounts are created for different scams. If you are part of the first wave of spam emails, there won’t be any evidence online. So, double-check everything. If you receive a letter from your bank or any other organization, go to their official website. There, under the contact section, you can find their authorized email addresses. Compare them with the one you have received a message from. If they don’t match, delete the spam email immediately. Don’t risk your computer’s health. Do your due diligence. Stay away from shady websites and don’t follow links blindly. Neither should you neglect your anti-virus software. It is not hard to keep it up to date.
