How can you protect your PC from .Lock file extension virus?

If you have been aware of recent ransomware attacks, you should know about a newly launched .Lock virus. We would like to remind you that ransomware is programmed to invade computers and encrypt valuable data. The virus demands a ransom in exchange for the locked files. Since more than a dozen of ransomware has been released already, the demanded sum varies each time: from $400 to even 1000 dollars. If by any chance this menace has fallen upon you, first of all, you need to collect yourself. Do not consider making the transaction. Cyber criminals have already collected astounding amounts of money but reports about the return of data remain just a few. Thus, it would be more useful to think about .Lock removal options.

According to the ransom note, it seems that the ransomware targets users residing in Spanish-speaking countries. However, you should bear in mind that the virus might pay a visit to your computer as well, even if you live in Canada or India. .Lock file extension virus uses AES 256 encryption code like other viruses of the same kind. It has been observed that there is a growing tendency for cyber criminals to propose victims to decode the files not only using a decryption key but specific software as well. It is often presented as a decoder. Certainly, we discourage installing any program offered by ransomware creators. Even if the locked files are of huge importance to you, you need to acknowledge the fact that hackers only exploit victims to spread the virus further. If by any chance, you download their promoted decoder, you might recover the data. However, the risk that ransomware infects your computer after a while significantly rises.

The note of .Lock extension virus

How did .Lock malware attack my computer?

Regarding the fact that it operates similarly to other ransomware, the virus might have invaded your computer via a recent email with an infected attachment. Most likely, the email deceived you by alerting you with a false invoice or notification seemingly sent by a governmental institution. Thus, it became a matter of time when the virus went on a rampage on your system. After the attachment was enfolded .Lock ransomware activated itself and then it started searching for potentially important files, such as work related reports, accounts, family photos. For a while, you might not have the slightest idea that a damaging virus has taken control of your computer. Depending on the size of your hard drive and CPU speed, within few minutes or an hour, a ransom note pops up on the screen declaring of the locked files. It urges you to pay $549 for the software and the private key to unlock the files. Certainly, you should try to remove .Lock extension virus instead. One of the methods to do it is to run a system scan using Reimage.

Additionally, we should warn you to be cautious that the malware might spread via exploit kits. These files might be either script, minor files or trojans. Though this method of distribution is not widely used, some cyber criminals do not exclude this opportunity. Comparing with the first transmission method, this way of spreading is significantly more destructive. While in the first case you might reduce the risk of ransomware hijack by not opening the suspicious emails, in this case, only a powerful anti-spyware program might protect the computer since exploit kits hide in legitimate websites as well. Thus, let us proceed to the elimination process.

How can you remove .Lock file extension virus

There are two elimination options – manual and automatic. You could try using manual elimination guide. Nonetheless, you need to take into account the malicious behavior and complicated structure of this .Lock virus, so precision and utmost attention are required to get rid of the ransomware completely. Some users might find the instructions too complicated, so we recommend installing an anti-spyware program. It will detect and complete .Lock removal much faster than you.
