Cybercriminals encrypt certain files or all of the data on your computer to demand a ransom. Fortunately, it is possible to remove ransomware using software and subsequently make backups.
Removing ransomware: what is it?
Ransomware is not only a huge nuisance, it can even become a danger to your device and your data. In such an attack, your system becomes infected with malware that encrypts certain files or even the entire operating system, preventing you from accessing it. to access. Cybercriminals then usually ask you to pay a ransom to allow you to regain access to your data. The infection usually occurs via emails, specific downloads or dubious websites. Fortunately, there are many recommended methods for protecting yourself from ransomware. If infected, you have no choice but to remove the ransomware.
How to recognize ransomware?
Before you can remove ransomware, you should first ask yourself how to detect blackmail software like WannaCry. In the worst case, the program reveals itself by blocking parts of your system and demanding a ransom. Please note that you can also detect an attack beforehand and implement preventive measures. The following signs may indicate an infection:
-
Abnormal analysis : Effective antivirus scanning recognizes most common ransomware programs and helps you remove them in time. If the ransomware manages to bypass the virus scan, your system may still be infected.
-
Workload : If you notice that your system is being used unusually intensively, that some programs are suddenly running much slower, or that crashes are more frequent, then you may be dealing with ransomware.
-
Change file name : If files suddenly show other names or file extensions have been changed without your input, this is usually a first sign of infection.
Should we respond to ransom demands?
If such an attack occurs, you certainly have the option of paying the requested ransom. However, this solution is not not recommended. On the one hand, it is expensive and on the other hand, you have no guarantee that a payment will actually lead to the kidnappers returning your data. Rather, they may demand a larger sum or break contact after payment and keep the data encrypted. So it is always better to remove the ransomware.
How to remove ransomware when files are affected?
Here are the different steps to follow to remove the ransomware and recover infected files:
-
Cut the Internet connection : To prevent the malware from spreading further throughout your network and to make it more difficult for blackmailers to gain access, start by disabling all connections to the Internet. This not only concerns a possible LAN connection, but also all wireless connections, clouds, external hard drives or other devices.
-
To restart : Turn off the computer and restart it again. Although this step unfortunately does not guarantee ransomware removal, you should at least try restarting your computer.
-
System analysis : Now launch your antivirus software and perform a full scan of your system. A possible infection can be detected on this occasion, allowing the program to delete the affected files or at least quarantine them. This way, they will no longer be able to cause damage. Other Trojans are also removed.
-
Decryption Software : If the files are already infected and traditional antivirus software can no longer improve the situation, you can use special software to remove the ransomware. These are adapted to new threats and unlock encrypted data with a high success rate.
-
Use a backup : If you have created a backup of your data, you can now use it. If you don’t have a backup, you may need to recreate some infected files. In any case, once the problem is resolved, perform a rescan to ensure that all problematic files have been removed.
Remove ransomware in case of total system lockout
Unfortunately, there is also ransomware that not only attacks files, but directly locks the whole system. Most of the time, the ransom note is displayed directly on the home screen. You then have no access to any other programs and therefore cannot start antivirus software. One possibility to remove ransomware is to switch to mode saved. If you start your computer in this way, the malware often cannot intervene yet and you can remove it from the system using the methods mentioned above.
How to protect yourself against ransomware?
Ransomware is also constantly evolving, so there is no complete protection against infection. However, if you protect your system
- always keeping it up to date
- by not opening unknown files
- by making regular backups
- by focusing on an effective security system
the danger will at least be limited in the best possible way. Additionally, these precautions make it easier to remove ransomware without losing files.
