This page aims to help you remove Koolova Ransomware for free. Our instructions also cover how any Koolova Ransomware file can be recovered.
When it comes to cyber infections, the biggest numbers of them ever recorded have been caused by Trojans. Nevertheless, the most awful ones have been caused by different versions of Ransomware. That’s why we have written the article below – to help you understand the nature of one particular Ransomware – Koolova, and to find out how to counteract this incredibly dangerous contamination in a wise, and hopefully, successful way. Broadly defined, Koolova is a data-encrypting type of Ransomware that sneaks into your system without asking you for your approval; and then makes you unable to reach the data it blocks. After that, this evil piece of software generates a message to let you know about what the hackers behind such a cyber-attack expect from you.
What to expect from Koolova Ransomware:
As a data-encrypting version of Ransomware, this particular virus usually performs a rigorous file-encryption process. It usually takes place after the program has already determined which files you will miss the most. In fact, the virus not only defines the files that will be encrypted, it also creates a very detailed list with all such data. After that, you may be awarded with the message, stating that you owe the hackers your money and you need to pay them before a stated deadline if you want them to return your data intact. Please, note that sometimes the entire process of encrypting data could be noticed while it’s still going on. However, it only happens rarely – in exceptional cases. Still, in case you see an unknown process taking place in your Task Manager, please, turn off your computer and ask an expert for help. It could be a version of Ransomware blocking some super important data.
Little could be done after the entire encryption process finishes. Unfortunately, the file-encrypting viruses are incredibly hard to fight. In fact, even experts could find it awfully difficult to remove the virus without paying the wanted ransom and to save the hijacked files at the same time. Also, in most of the cases only one of the aforementioned is possible. As awful as it sounds, there is indeed a very small chance of success when it comes to data-encoding Ransomware infections. Nevertheless, it doesn’t hurt to try to remove the contamination. Just explore your options before you agree to pay the required sum of money to the cyber criminals who are disturbing you. For example, try asking an expert for advice. Or maybe – purchase some special software to counteract the infection. Also, another option is to try our special Removal Guide below. Perhaps it will be what you need to restore your files and remove the virus.
How is it most likely to come across a version of Ransomware?
Hackers may distribute these horrible viruses in many ways:
- Via emails and their attachments: Some emails, especially the ones from unknown senders, could be transporting Ransomware. Such viruses could also be included in the attachments of any unfamiliar letter inside your email. That’s why we strongly recommend that you ONLY open the emails and the attachments that you expect to receive. All the others are potentially dangerous. What’s more, the Ransomware could be transported together with a Trojan, which could make the chances of getting rid of both the infections highly improbable.
- Via the so-called malicious pop-ups and banners (Malvertising): Malvertising is another potential source of Ransomware. In this case your system will automatically catch a virus once you have clicked on the contagious ad, no matter whether it has happened intentionally or unintentionally.
- Sometimes you may be tricked into catching Ransomware by fake update requests: It is possible to receive fake update requests – not generated by your system, but working as the malicious ads. Unfortunately, most of them really resemble the original ones. To avoid such a chance of getting infected with Koolova, please update your system manually and check for updates yourself.
Of course, there may be many other possible sources of Ransomware such as torrents and movie/torrent/video-streaming websites and others. The ones described above are the most common ones.
Some general tips
- Do not venture into paying the required ransom immediately. Look for another potential solution. Obviously, your files are already in danger; do not risk your money as well.
- Make an effort to stay away from all potential sources of this terrible software. Practice avoiding them and eventually you will learn how to do that.
- Invest in the best anti-virus system. The newest ones usually have the most detailed databases and the program will be able to warn you against potential contagious places; or even to remove an infection already caught.
