What is Ransomware?
Ransomware is a type of malware that encrypts data on a targetted computer or network. Depending on the files targeted, the system could be rendered useless. Ransomware is used by cybercriminals for monetary gain. The operators behind the ransomware typically offer victims a way to decrypt the encrypted files by paying a ransom usually in the form of cryptocurrency.
How Does Ransomware Spread?
Ransomware is transmitted to computers through attachments via spam or phishing emails. Once the ransomware is successfully implanted into a computer, it encrypts files that are then rendered useless. Ransomware will normally offer victims a way to decrypt the encrypted files for a fee, which is generally paid by credit card and sent in Bitcoin.
How Does Krlock Ransomware Work?
Krlock Ransomware works by infiltrating an infected computer system and encrypting specific files. If the victim wants to decrypt locked files, they will have to pay a ransom to unlock them. The encryption of Krlock Ransomware is done through AES 256-bit encryption.
Once installed, ransomware connects back to a command-and-control server which allows attackers to monitor and control the ransomware's actions, such as letting it send spam emails or shutting down user access if they failed to pay the ransom for multiple days in a row. The cybercriminals behind the ransomware attack usually demand their ransom in Bitcoin. The ransomware will set a lock screen to notify the user that their files are encrypted and demand a ransom in order to decrypt it.
How to Remove Krlock Ransomware
The first step for removing Krlock Ransomware would be to restart your computer in safe mode with networking service disabled. This will disable the ransomware from running and moving any information around your computer, which is not accessible without paying up. If you're unable to restart your computer into safe mode, try booting it into an alternate operating system such as Linux or Windows 10 (free).
When trying to remove Krlock Ransomware, you should run a reputable antimalware program that will detect and remove all the components of the ransomware including its binaries, files, and network connections. A quick scan of your system with an up-to-date antimalware program should quickly remove the ransomware from your computer.
If you're still unable to remove Krlock Ransomware after using an antimalware program, you will need to manually remove components of the ransomware from your computer. If one file came with a ransom message, then you can either delete it or contact a support person who provides information on how to decrypt files if you paid the ransom for them.
How to Protect My Computer From Ransomware
The first step for protecting your computer from ransomware would be to update your antimalware software. If you're using an outdated antimalware program, malware can get through the protection without detection. Antimalware programs are often found on the internet, and you should install one as soon as possible in order to prevent any ransomware infection.
It's also important to keep your computer's operating system up-to-date because this allows it to operate more efficiently and effectively handle incoming threats and suspicious behaviors. The last thing you want is for your computer system to slow down or stop working because of a virus or malware leaving it vulnerable without warning or detection by the antivirus program installed on it.
