AiraCrop virus Removal Guide
What is AiraCrop ransomware virus?
AiraCrop – crypto-ransomware virus keeps attacking people since 2016
AiraCrop is a ransomware virus that has been first detected at the end of 2016. Currently recognized as Win32/Filecoder.AiraCrop.A Trojan by most of the reputable AV engines, it seems to be kinship with the infamous NMoreira ransomware. According to ransomware research team from Dieviren.de , AiraCrop ransomware uses a combination of AES-256 and RSA-2048 encryption algorythms and appends ._AiraCropEncrypted! file extension to each locked file. Following the encryption, ransomware payload generates a ransom note, which instructs the victim to download Tor browser, heed to the required website by clicking on one of the links, and indicate the unique identification number to get payment instructions. In the beginning of April 2018, experts warned about AiraCrop reborn after they found a new variant Aira circulated on the net.

|Removal||Possible with a professional anti-malware only. Download ReimageIntego and run a scan.|
AiraCrop ransomware did not manifested as one of the most sucessful cuber threats from the perspective of its developers. Although initially compared to the infamous CrySiS, it did not achieve a half as much as CrySiS did. Nevertheless, it keeps attacking people all around the world since 2016 and managed to collect ransom almost each day.
It has been found that this ransomware likewise its kinsman spreads via Exploit Kits, hacked websites, rogue software downloads, malicious spam email attachments, and similar means. As soon as its payload is being executed, AiraCrop virus starts scanning the system and searching for targeted files. The following are the file types that it is capable of encrypting:
.Png, .psd, .pspimage, .tga, .thm, .tif, .tiff, .yuv, .ai, .eps, .ps, .svg, .indd, .pct, .pdf, .xlr, .xls, .xlsx, .accdb, .db, .dbf, .mdb, .pdb, .sql, .apk, .app, .bat, .cgi, .com, .exe, .gadget, .jar, .pif, .wsf, .dem, .gam, .nes, .rom, .sav, .dwg, .dxf, .gpx, .kml, .kmz, .asp, .aspx, .cer, .cfm, .csr, .css, .htm, .html, .js, .jsp, .php, .rss, .xhtml, .doc, .docx, .log, .msg, .odt, .pages, .rtf, .tex, .txt, .wpd, .wps, .csv, .dat, .ged, .key, .keychain, .pps, .ppt, .pptx, .ini, .prf, .hqx, .mim, .uue, .7z, .cbr, .deb, .gz, .pkg, .rar, .rpm, .sitx, .tar.gz, .zip, .zipx, .bin, .cue, .dmg, .iso, .mdf, .toast, .vcd, .sdf, .tar, .tax2014, .tax2015, .vcf, .xml, .aif, .iff, .m3u, .m4a, .mid, .mp3, .mpa, .wav, .wma, .3g2, .3gp, .asf, .avi, .flv, .m4v, .mov, .mp4, .mpg, .rm, .srt, .swf, .vob, .wmv, .3d, .3dm, .3ds, .max, .obj, .r.bmp, .dds, .gif, .jpg, .crx, .plugin, .fnt, .fon, .otf, .ttf, .cab, .cpl, .cur, .deskthemepack, .dll, .dmp, .drv, .icns, .ico, .lnk, .sys, .cfg.
Upon encryption, each file gets ._AiraCropEncrypted! file extension, which cannot be modified or removed manually. It's not very likely that these files will be recovered manually. The only way to retrieve them is to pay the ransom (not recommended) or remove AiraCrop ransomware using ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes security tool and then take advantage of third-party data recovery programs.
AiraCrop ransomware virus demands a ransom, though its size is not clear up until now. Once the system is attacked, the malware locks files and generates a .txt file, which explains what happened and urges to download Tor browser asap. The new Aira ransomware is known for generating a notepad file called How to decrypt your files. Criminals instructs victims to contact them via email@example.com. The AiraCrop ransom note says:
All your files are encrypted. Using encryption AES 256-bit and RSA-2048-bit.
Making it impossible to recover the files without the correct private key.
If you are interested in getting is key, and retrieve your files
visit one of the links and enter your key;
To access the alternate link is mandatory to use the TOR browser available on the link
As you can see, the note is rather obscure. The criminals do not provide any detailed information such as the amount of the payment nor the deadline for it to be issued. However, we can see that like the majority of ransomware viruses AiraCrop uses the anonymous TOR network to collect payments.
AiraCrop ransomware locks personal files and demands to pay a ransom to get a personal decryption tool.
We can also gather that the criminals use military grade AES 256-bit and RSA-2048-bit encryption algorithms that are also favored by such ransomware giants as Locky and Cerber ransomware.
This only proves that these hackers are not playing games and will not give back your files that easy. And you should not try satisfying their greediness either. Remove AiraCrop from your computer without giving in to the hacker’s plan and, hopefully, this will help decrease the hackers’ motivation to create similar malware at least a little.
Ransomware tricks people into opening malicious email attachments
Most likely, the virus is carried around by a malicious spam campaign that makes sure this malware enters computers without the victims even realizing it.
Typically, malware infected files will end up in the “Spam” section of your email, but beware that they may obfuscate the malicious files and slip them through the security filters straight into your inbox. In such a case, it is beneficial to know how to recognize such malicious emails.
The first thing to pay attention to is the sender — you should not receive emails from unknown third-parties unless you have provided them with your email yourself. Otherwise, it is either a commercial spam or malware. You probably do not want to deal with any of these. You should be especially careful with emails that feature attached documents or links. Investigate these attachments before opening them and double-check whether they were really meant for you.

How to prevent from getting ransomware
Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
