Why do my documents and pictures have .kyra file extension?
The .kyra file extension virus is a new version of the Globe Ransomware. Malware does not differ a lot from other file-encrypting viruses: it is distributed via malicious email attachments, after infiltration encrypts files using a sophisticated algorithm and drops a ransom note. Compared to the current popular and dangerous viruses, it might seem that .kyra file extension ransomware is not a hazardous cyber threat – it targets “only” 100 different file types. Indeed, some malware might target four times more file formats. But keep in mind that it targets the most popular files such as .jpg, .doc, .xls, .ppt, .pdf, .mp3, etc. There’s no doubt that all your important work or study documents, pictures from holidays and birthday parties, music or movies collection are taken to hostage. Malware encrypts files using powerful RSA-1024 encryption algorithm and demands a ransom for decryption tool. Victims have to contact hacker and transfer a necessary amount of money; however, this activity might lead to an even bigger loss. Instead of dealing with cyber criminals, remove .kyra file extension virus from the computer. Ransomware elimination is quite difficult and complicated task, so we recommend employing a strong and powerful malware removal tools such as ReimageIntego or SpyHunter 5Combo Cleaner. These programs are created for protecting computers and removing malware.
Questions about .kyra file extension virus
The most significant feature of the virus is its file extension. Malware “marks” corrupted files with .kyra file extension. Since then users cannot access their personal data and might receive Windows Explorer’s alert that it cannot recognize the file type. Once it happens, users can look for a ransom note called “STRIKE.HTA” that is probably placed on the desktop. Here victims can learn what have happened to their files and how they can get back access to them. Hacker gives 48 hours for users to contact him (or her) by email support-lodang@India.com or using bitmsg.me service, and send their personal key which is provided in the message. The creator of .kyra file extension virus will answer them and send a unique Bitcoin wallet address, where victims have to transfer 1 BTC ($620) in order to use a unique file decoder. However, we do not recommend contacting the hacker and paying the ransom. According to various cyber security specialists, hackers rarely provide necessary data decryption key after they receive a payment. We want to discourage you of transferring the money. Instead of it, initiate .kyra file extension removal.
How can my computer get infected?
Virus researchers found out that .kyra file extension malware spreads via malicious spam emails. We are not surprised about this distribution technique. It seems the most effective and successful infiltration method. It’s already known that this virus sends emails that are supposed to be job applications with attached CV or payment confirmations from various online stores. Therefore, you have to be careful. Before opening an attachment, make sure that you have bought something from a particular store or that your company calls for candidates. If not, do not open these emails. Besides, other file-encrypting viruses might be hidden under different messages, so you should always double check the information before opening attached documents.

Stream videos without limitations, no matter where you are
There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.
Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.
Data backups are important – recover your lost files
Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.
While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
