Jamper virus Removal Guide
What is Jamper ransomware?
Jamper ransomware – malware which accepts Bitcoin payments in exchange for decryption software
Jamper ransomware is a file locking infection which adds the .jamper appendix to all encrypted objects
Jamper ransomware is a dangerous malware form which was lately discovered by a computer researcher named Michael Gillespie. This file-encrypting threat affects Windows computers by injecting rogue registry keys and running malicious processes. These actions allow Jamper virus to launch the encryption code and block all files that are found on the targeted device. Later on, all affected data appears with the .jamper extension and an informative —README—.TXT message bombards the computer screen. Ransomware developers threaten users that their files are locked and can be recovered only by purchasing the decryption key from the crooks. These criminals, as most of the hackers, urge for Bitcoin as such transfers always remain secret and untrackable. Moreover, these people provide some contact information for the victims: firstname.lastname@example.org, and email@example.com email addresses.
|Price||The ransom price often varies from $500 to $1500 in BTC|
|Encryption code||AES cryptography|
|Emailsfirstname.lastname@example.org, and email@example.com|
|Distributing||Spam messages and infected payload are the main ransomware distribution sources|
|Detecting||Find malicious content in your Windows system with ReimageIntego|
Jamper ransomware is known as a data locker which uses AES cryptography to execute the unique code and encrypt all files that are found on the infected Windows computer system. Once data is blocked, users are not capable of accessing the information properly anymore. Once tried to open, the file usually appears broken or does not launch at all.
Continuously, the cybercrooks who spread .jamper files virus store both encryption and decryption keys on remote servers which are accessible only for the owners themselves. However, this does not mean that you should make fast decisions and instantly pay the cybercriminals, otherwise, files will be lost forever as claimed in the ransom message:
All your important files are encrypted
There is only one way to get your files back: contact with us, pay, and get decryptor software.
We accept Bitcoin
You have Your personal identifier, write it in letter when contact with us.
Also you can decrypt 1 file for test, its guarantee what we can decrypt your files.
Do not rename encrypted files.
Do not try to decrypt using third party software, it may cause permanent data loss.
For decrypt your data write to email
As an alternative, we recommend trying some data recovery software which might appear to be helpful and let you restore some of your important locked files. However, first, you need to remove Jamper virus and all malware-related content from the system which can be detected by anti-malware programs such as ReimageIntego or SpyHunter 5Combo Cleaner.
You need to take fast actions against the file-locking malware and perform the Jamper ransomware removal as soon as possible. Such malware sometimes comes with several hazardous and damaging features. For example, ransomware might also be capable of installing other dangerous computer viruses on the system or running infected payload in different locations.
Additionally, Jamper ransomware might be capable of bypassing the computer's security programs which allows it to freely distribute on the entire system. Nevertheless, this file-encrypting threat might be capable of launching a module which collects sensitive information about the user. All these malicious activities might renew themselves with each computer boot if the virus has not been terminated correctly.

Cautiousness is the main key to computer security
It does not matter if you have an antivirus program or not if you do not take care of it properly. Antivirus software is truly a helpful option to avoid possible malware infections and keep your computer system always clean. However, you will need to perform regular updates once in a while to make sure that the program functions properly.
Continuously, according to technology experts from the LosVirus.es page, ransomware distribution is related to email spam campaigns. Be aware that crooks might drop messages claiming that they are from official organizations and are writing for very important purposes. Investigate the letter before opening any clipped attachments.
Other ransomware spreading sources can be:
- Peer-to-peer networks.
- Infected downloading hyperlinks.
- Malicious ads.
- Malware-related software.

How to prevent from getting ransomware
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.
