The code of an encrypting virus isn't really complex, yet even the very carelessly developed virus is very perilous, and we will prove our point. They all use the very complex methods of encryption. Viruses don’t take your data. It just needs to penetrate the PC, encode your files and remove the initial data, putting the encrypted copies instead of them. The files are useless if they are encoded. You cannot read them and can’t restore them. We know not many techniques to recover the files, and they all are written down in our item.

The encoding malware, AKA ransomware, are the viruses that infect customers' systems and spoil their info to earn money for its decryption. Most times, hackers get on victim's device via malspam campaigns or zero-day vulnerabilities. Perilous mail is not difficult to recognize – it will be a message suddenly, with some files attached to it. If we're talking about 0-day Trojans, it’s a bit harder – you'll never feel that it's coming until you get taken over which means that the most efficient way is to properly download the newest updates for the OS and other utilities which you have in it.

The catch is that all encrypting programs take advantage of the well-known encoding systems, such as the AES and the RSA. These two are simply the most sophisticated in the world, and an ordinary user cannot decrypt them. Of course, you might break them if you have a hundred years of common computer’s operation time or several years of operation on the most powerful machine on the planet. We do not think that any of these options is suitable a user. The easiest technique to beat ransomware is to not let it get onto the computer, and we'll explain to you how it could be done.

If the job is done, fraudsters give you a ransom note, and is you see it – you can be certain that the data are corrupted. There is only one turn you can take now - to delete a virus from your device and attempt to recover the information. We've said “try” because the probability to handle it not having a decryption tool are ghostly.

Summary

 

How to remove Dotmap

It’s very important to delete Dotmap until you go on since if it sticks on the computer – it will start encoding each file that enters the hard drive. Even more - each device you're sticking into the infected machine will get corrupted also. To avoid that – remove ransomware through adhering our useful advice. Remember that the uninstallation will not recover the data, and after doing it, you will not be able to pay the ransom. We suggest you to do that since each ransom gained makes hackers more to feel their feet in their "business" and increases their money to create complex viruses. Another point is that when you are forced to deal with scammers, they can simply steal the money and forget about you. They have already decrypted your data, and you, supposedly, don't lean to give them some money after that.

When the virus is removed from your computer, and you double-checked it, it’s time to consider the restoration ways. Primarily, we want to notice that the very proven way is to use the backup copies. If you have the copies of your files and the ransomware is destroyed – simply remove the encrypted files and load the backups. In case you had no backups – the chances to restore your files are slim to none. Shadow Volume Copies tool is what helps you to do it. It is the inbuilt service of the Windows OS, and it saves each bit of information that was modified. You might come at them via specific recovery utilities.

Of course, the modern encrypting programs may erase these files, but if you're accessing the system from an account that has no admin rights, Dotmap just couldn’t perform that not having the permit. You may recollect that a few minutes prior to the showing of a ransom letter you've seen another dialogue window, offering to apply changes to the system. If you have cancelled those alterations – your SVC weren't erased, so they can be found and used through the utilities as Recuva or ShadowExplorer. Both of them might be found on the Internet. Each of them has its main websites, so you better download them there, with tested instructions. In case you need more explanations on this topic – feel free to look at the extended guide about file restoration: article about files decryption.
