Wiki Ransomware (. Wiki Files) — How to Remove Virus?

Wiki Virus

After the encryption process files will be renamed according to the pattern [idxxxxx].[email].wiki, which is laid in ransomware. Your photo, named an example “me.jpg” will be altered to “me.jpg.id-1E857D00.[ ].wiki” after the encryption.

FILES ENCRYPTED.txt file, which can be found in every folder that contains the encrypted files, is a ransom money note. Inside of it, you can find information about ways of contacting Wiki ransomware developers, and some other info. Inside of the ransom note, there is usually an instruction saying about purchasing the decryption tool. This decryption tool is created by ransomware developers.

The FILES ENCRYPTED.txt file by the Wiki ransomware states the following frustrating information:

How did I get Wiki ransomware on my computer?

However, nowadays there are only two ways of Wiki injection – email spam and trojans. You may see a lot of messages on your email, stating that you need to pay different bills or to get your parcel from the local FedEx department. But all such messages are sent from unknown email addresses, not from familiar official emails of these companies. All such letters contain the attached file, which is used as a ransomware carrier. If you open this file – your system will get infected by Wiki.

In case of trojans presence, you will be offered to download and install ransomware on your PC under the guise of something legit, like a Chrome update, or update for the software you are storing on your computer. Sometimes, trojan viruses can be masked as legit programs, and ransomware will be offered for download as an important update, or a big pack of extensions which are essential for proper program functioning.

There is also the third way of ransomware injection, however, it becomes less and less popular day-to-day. I am talking about peering networks, such as torrents or eMule. No one can control which files are packed in the seeding, so you can discover a huge pack of different malware after downloading. If circumstances force you to download something from peering networks – scan every downloaded folder or archive with antivirus software.
