Ransomware is an increasingly common form
of malicious software that can block access to computers, devices, specific
files and sometimes cloud storage. Cybercriminals use ransomware to extort
money from their victims. Once a computer or device has been infected with
ransomware, cybercriminals demand payment to restore access to their device.
Payment is usually requested in the form of anonymous currency, such as
Bitcoin, but some victims have been ordered to make cash drops in public
locations. If your computer or device has been infected by ransomware, you need
to take swift action to minimize the damage.
Disconnect All Devices
The first thing you need to do when you
discover a ransomware infection is to prevent it from spreading to other
devices sharing the same network. Disconnect the infected computer or device
from the Internet, all networks and any connected devices as soon as possible,
remembering to turn off Wi-Fi, Bluetooth and any other connections. If
possible, turn your device off, as this may interrupt the ransomware attack
before it can be fully executed.
Report the Attack
Social media, websites and forums can
provide useful information about specific types of ransomware and how to remove
it. Several Facebook groups, Twitter hashtags and forums have been set up by
members of the public to help stop the spread of malware. Reporting ransomware
and other malicious software attacks through social media and forums enables
these anti-malware groups to gain more insight into the current techniques used
by cybercriminals.
Remove the Infection
Ransomware removal is not always possible,
as cybercriminals are continually finding new ways to prevent the detection and
removal of malware. However, some types of ransomware can be removed using
tools offered online. For example, Trend Micro, a security software company,
provides a Ransomware Screen Unlock Tool, which can help users to regain access
to locked computers and devices. Other security companies offer similar tools
and file decryption software that can be used to regain access to specific
files.
Wipe Your Device
If the ransomware removal tools don't
work, your best option may be to wipe your device and reinstall your operating
system. While this means you will lose any unsaved data, it may be possible to
restore files from previous backups that were automatically performed by your
operating system or security software. Check the help files or online
literature associated with your operating system, security program and backup
software to see if you can salvage your data.
Unfortunately, it's not always possible to
remove a ransomware infection, particularly when it comes to the more recent
versions. However, while you may not be able to salvage your unsaved data, you
should be able to wipe your device and start again with a clean system. If you
have important data that you don't want to lose, it can be tempting to pay the
ransom, but there is no guarantee that the cybercriminals will return access to
your device. Therefore, most security experts advise against making payments.
