.lock Ransomware – How Did I Get It and What Does It Do?
There are several different types of methods used to spread the .lock ransomware virus. They all involve getting victims to either click on a malicious URL or manually download and run the virus infeciton file. One of the methods used to spread this malware is likely by uploading it on a site, where it may pretend to be a program of some sort, like a license activator, crack, patch, key generator, portable program or other form of software. These programs could be on a compromised site, where you may be tricked into manually downloading them, thinking they are useful. One such file could end up to be the main infection file of the .lock virus:

In addition to this, the .lock malware may also come on your computer via being sent over as an e-mail attachment. There, the virus may appear as if it is a legitimate document that is very important, like a letter from your bank, an invoice or a purchase receipt.
Whatever the case may be, once you run the malicious file, infection is inevitable. The 123.exe file may spawn a file, called dll.exe. This file may perform series of modifications on your compromised computer, including the following activities:
- Interfere with your Windows Registry Editor.
- Check if it has infected your PC before.
- Delete backups and shadow copies from your PC.
- Bypass and disable Windows Recovery and other services.
