How to remove Topi virus and restore encrypted files

If you fell a victim of a ransomware and have grounds to expect that it is the Topi program – in our article you'll receive help. We propose easy and effective tips for Topi elimination and potential ways to recover the encrypted data.

What is Topi

Ransomware can be considered a roadkill of mankind, and we all know that if a pop-up says: “files are encrypted” – it’s time to be scared. It’s a correct reaction, unfortunately. Ransomware threat is the worst threat that you might meet on the Internet since a common user has no resources to delete it. The exclusive case when you're able to overcome an encrypting virus is when you aren't facing a true virus, but a screenlocker, that blocks the screen and attempts to deceive you into paying a ransom. In all other cases, if ransomware was developed and maintained in a right manner – you can only trust that specialists can deal with it. If scammers committed a mistake, and there are any flaws, that let you to recover files – you'll find a cure on this page.

 

 

Virus kind doesn't actually matter, as the AES and RSA algorithms are too complex to break them directly. It can take thousands of years to make all required operations on a common machine and, possibly, twenty or thirty years in case of usage of a super-efficient computer. The best way to defeat a decent encrypting malware is to hack into it, or hack its database, to get a master key. Some ransomware examples also have a breaker that can cease virus' operation in full or to make it pass the infected machine. If any parson finds such switch for this virus, or publish a decryption tool, we'll provide you with complete info in this guide.

 

Let's find out, what we'd discover if we take a glance inside a Topi? It consists of a totally legitimate coding system that encrypts the data on operator’s computer, so you can't use them in any approach. The key is also encoded with another method. As usual, swindlers prefer RSA and AES algorithms, that are famous for their complexity and fail-safety. The mentioned methods and the tools built upon them can be easily found in the Net, so scammers just need to add protective techniques, to restrict an admittance to a program, and create the reliable control and update scheme. Some encrypting tools may function independently, and scammers know about a new victim as late as he writes them and forwards the money. The complex viruses are very active, and deliver reports to hundreds URL's, to confuse the malware-fighters and throw them off virus’ track.

 

There are several methods to examine, until you can give in and await for a decryption program. As it is written above, fraudsters also fail, and some peculiarities of the operating system might serve you to restore information.

 

  • If your system entry doesn't have administrator rights – it's time to compliment yourself. The matter is that your OS makes copies of all information before they’re removed or changed. These copies are called SVC, and Topi has the methods to erase them. If you're using the usual entry – the system asks for a permission at the exact moment Topi attempts to delete those copies. In case you saw such confirmation and ignored it – then the SVC are secure, and you might download a topical tool to get back the files.
  • A protected copy is the only entirely productive method to get your files back, but you have to delete a malware before. Ensure that the malware is uninstalled fully, since if it’s not – all files will be messed up instantly, with the files that were kept on an outer hard disc.

 

In case you examined all these opportunities and you have no way to get back lost information – you need to uninstall the malware from the system and expect when a decryption program will be created.
