Errz Virus – How Did I Get Infected?
Errz virus is very similar to .hajd, .qall and .ghas viruses, that are also STOP/DJVU versions. And just like these variants, the virus may also infect your computer using the same methods, listed below:
- If it has been downloaded from some shady third-party software download site.
- If you have received it in the form of an e-mail attachment or a URL in your e-mail inbox.
If you have become a victim of this nasty infection via email, then there is a high probability that the file that may have caused the infection could’ve pretended to be a legitimate document, like the following examples:
- Invoice files.
- Receipt documents.
- Work-related documents.
- E-Tickets of some kind (flights, train, events).
These documents when download it and opened may trigger a malicious macro code if you enable their content:
Another way to get infected with this threat is if you download the file as an executable, if it has been uploaded to some type of software download site. If this is the case, then the files that are pretending to be legitimate, but are in fact are the infection may be the following:
- Patches for programs or games.
- SFX (self extracting) or regular archive files.
- Cracked applications or portable apps.
- Crack-fixes or activators for software or games.
- Keygens or key generators.
Errz Virus – What Does It Do?
Errz virus could firstly connect to a remote server, from where it may download its malicious payload files and module files. They could be located in the following Windows directories, where they could reside under different names:
- %LocalLow%
- %SystemDrive%
- %Local%
- %Temp%
- %System%
- %AppData%
- %Windows%
- %system32%
Among these files is also the ransom note of this nasty infection, which is also known as _readme.txt and carries the following extortionist message:
The Windows Registry Editor is also among the victims of this threat as it may situate multiple value entries, that may reside in the following Run or RunOnce sub-keys:
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
What Are .errz Files
Errz virus uses AES encryption to make your files no longer openable and ads its own extension, making them appear like the example below shows:
Picture.jpg.errz
Files that are attacked by this infection are scanned for based on their file extensions, for example the most often used ones:
- Files that are archives (.zip, .rar, etc).
- Various sorts of documents (.docx, .pptx, etc.).
- Audio file formats (.mp3, .wav, etc.).
- Different picture file types (.jpg, .png, .etc).
