CERBER 4.0.3 overall follows the classic ransomware pattern. Also, you should know the Web is full of ransomware parasites at the moment. Hackers seem to be quite interested in these infections. Do you know why? Because ransomware allows its developers to gain easy, illegal profit online. To become rich without any effort is every cyber criminal’s dream. Thus, ransomware’s popularity is steadily growing. We come across a brand new file-encrypting virus almost every day. Just like all programs of this kind, CERBER 4.0.3 firstly scans your machine. This way, it locates your personal data. The parasite goes after a huge number of formats including pictures, music, videos, documents. Long story short, all your valuable information falls victim to the virus. By using a complicated algorithm, this pest locks your files. It actually renames the target data and adds a malicious file extension. After CERBER 4.0.3 finds your pictures, music, etc., it copies them. Then the originals get deleted. You see, you’re left with the renamed, modified, encrypted files. Those are inaccessible. Your computer won’t recognize the file format so you won’t be able to open your data. Simple as that.

Therefore, keep in mind that ransomware is nothing but hackers’ nasty attempt to steal your money. They are messing with you. After encryption is complete, the parasite displays a ransom message. It usually gets added to all folders that contain locked files. According to that note, the only way to restore your files is by paying a sum of money in Bitcoin. The ransom varies between 0.5 Bitcoin (about 340 USD) and 1.5 Bitcoin (1020 USD). Don’t ever consider paying. Get rid of the parasite instead and don’t sponsor crooks’ illegitimate business.

Take no chances. When you stumble across a suspicious-looking email, delete it. You’d save yourself quite the headache this way. Also, ransomware gets spread online with the help of Trojans. Check out your PC system for more parasites because CERBER 4.0.3 may have company. Last but not least, avoid illegitimate websites/torrents/software bundles.
