How to Remove Ransomware?
Share this post
Ransomware is a software that locks or encrypts your files and requires payment to restore access. It is one of the fastest-growing cyber threats that targets individuals and businesses, and people often search the internet for how they can remove ransomware.
Back before computers, people kept important documents and valuables in heavy safes. Sometimes in broad daylight and sometimes in walls or floors under carpets. Today, we look at our laptop like it is a safe for our important documents and pictures etc, but we do not treat it like one.
That is why ransomware attacks are so devastating, because they hit us right where we store our most valuable digital assets. You can be blocked access to your family photos, business documents, or years of work overnight. One moment you are working normally, the next your files are locked.
Ransomware spreads through phishing emails, random downloads or updates, or due to weak system security settings. Ransomware displays a ransom note demanding payment in exchange for the decryption key. Hackers usually demand payment in cryptocurrency.
The good news is that there are safer and smarter ways to handle ransomware.
This guide will walk you through how to detect ransomware, remove it, protect against it, and understand the different types you may encounter.
How to detect ransomware attacks on my device?
Spotting ransomware early can save you from permanent data loss. Here are the most common signs of an active ransomware attack:
- Your antivirus software starts going crazy with alerts
- Files suddenly have weird extensions instead of .jpg, .doc, or .pdf
- File names change to random letters and numbers
- Your computer slows down dramatically
- Strange network activity you didn’t initiate
- Files won’t open anymore
- A message pops up demanding payment in Bitcoin or another cryptocurrency.
If you notice any of these signs, consider treating it as urgent. The faster you respond, the better chance you have to contain the damage.
How to remove ransomware? What are my options?
How to remove ransomware from your device is an extremely specific task. Specific to the variant of ransomware you are infected with. Removing ransomware can feel overwhelming, but you do have options. The right approach depends on the type of ransomware, how badly your device is affected, and whether you have backups in place or not. Below are the most common methods cybersecurity experts recommend:
Disconnect the ransomware-infected device from Wifi or any internet resource. Also, disconnect it from other devices to stop ransomware from spreading to your other devices.
Some ransomware types are easier to remove than others. Running the internet security tools like antivirus or anti-ransomware helps you identify any existing threats to your system. You can then either delete or quarantine these threats using the antivirus software automatically. Removing these malware files manually is not recommended unless you are a tech-savvy user.
Restart your computer in Safe Mode and run a full scan with a reputable anti-malware or antivirus solution. These can sometimes remove the ransomware program itself, though they might not decrypt infected files.
Booting the system into safe mode is helpful in countering screen-locking ransomware where the user cannot access the security softwares because they are blocked access to any relevant screen. Restarting in Safe Mode gives you a possibility that the screen-locking action will not load and then you can use your antivirus program to fight the malware. This will also erase any other malware from your device before you actually log-in and try to recover the corrupted files.
Many cybersecurity companies publish free decryption tools for known ransomware strains. You can upload a few sample files to the “No More Ransomware“ project website. They will try to tell you what variant the ransomware is and if you are lucky they might be able to give you the decryptor to get all your data back for free. Reputable companies like Kaspersky, Bitdefender, and Malwarebytes also offer free tools that may help remove certain ransomware families.
Some older ransomware variants have public decryption tools available. Security companies often release these for free once vulnerabilities are found.
If you have offline or cloud backups then remove the infection files first and then restore your files from the backup. Always remember to follow the 3-2-1 backup rule that is keep three copies of data, on two different media, with one copy offline.
If using the anti-ransomware software fails and your files remain locked, you may need to wipe your system.
- Back up unaffected data
- Format the drive
- Reinstall Windows or macOS. This will ensure no hidden malware remains in your device.
After cleanup, apply all security patches and updates. Change your passwords and enable multi-factor authentication. Consider investing in endpoint security solutions for ongoing protection.
For businesses or severe cases, call an incident response team to reduce risks. Cybersecurity experts can not only remove the infection but also investigate how it entered your system. They may recover encrypted data using specialized tools unavailable to the public. In many cases, professionals also help strengthen your defenses to prevent repeat attacks.
Should I pay the ransomware money or not?
The big question is: should you pay the ransom? While it might feel like the fastest way to get your files back, paying the ransom is generally not recommended by cybersecurity experts. There is no guarantee that attackers will give you the decryption key after payment, and in many cases, victims lose both their money and their data. Paying also fuels the ransomware industry and encourages more attacks on others. It should only ever be seen as a last resort when no backups or recovery options exist.
What are the types of ransomware?
Not all ransomware is the same. Here are the most common categories:
- Crypto ransomware encrypts your files and demands payment for decryption.
- Screen-locking ransomware locks you out of your device until ransom is paid.
- Scareware displays fake warnings or messages to trick you into paying for “fixes.”
- Leakware/Doxware: Threatens to publish your private files unless you pay.
Knowing the type helps you pick the right response, whether it’s a decryptor tool, a system reset, or professional recovery.
How to protect against ransomware in future?
There are a number of key things you can do to further protect your network security and devices from ALL attacks, not just ransomware.
- Harden the security in your home router. Many routers, the device connecting you to the internet in the first place, have a section for firewall rules.
- Turn off the internet or at least wifi and all devices at night. If you are always connected then you are a target 24 hours a day. If your systems are only connected from say 9AM -9PM then you are already 100% secure 50% of every say.
- Use strong WiFi encryption such as WPA3 if possible or WPA2 at minimum.
- Change passwords monthly and make them complex with numbers, symbols, and mixed case
- Never open unexpected attachments, even from people you know
- Preview links before clicking. Hover over links to see where they really go
- Watch for spelling mistakes because legitimate companies do not send emails with typos.
- Use 2FA (2-factor authentication) to secure your email and other online accounts.
- Make sure all devices are equipped with an anti-virus/malware along with surfing protection, and keep it up to date. For example, use Microsoft Defender on Windows or XProtect and Gatekeeper on macOS. Set a minimum weekly full scan of devices.
- Keep all your devices updated with software updates.
- Setup encryption on your device’s hard drives.
- Always follow the 3-2-1 backup method, especially for your important files.
- Ignore suspicious pop-up and never pay for unknown “repairs.”
What is 3-2-1 backup method?
The 3-2-1 backup method is a simple strategy to keep your data safe and recoverable:
3 - Store at least three copies of important files.
2 - Keep files on at least two different storage mediums (hard drive, solid state drive, cloud storage, NAS, external drive, etc.).
1 - Keep at least one copy offsite. In the event of a disaster such as a house fire or cyberattack, you will want a copy of your data to be recoverable. Storing it away from your other copies will help ensure availability.
What is RaaS?
Raas stands for Ransomware-as-a-Service (RaaS).
Skilled hackers create ransomware kits and sell or lease them on the dark web, making attacks easier. Even attackers with little technical knowledge can launch ransomware attacks by paying for RaaS. The creator usually takes a percentage of the ransom payments, while the “affiliate” (the buyer) keeps the rest.
It is basically a business model for hackers on the dark web offering subscription services for digital criminals.
Conclusion
Ransomware is one of the most stressful cyberattacks to deal with, but let’s not feel powerless. You can minimize the damage by learning how to detect it and understanding your removal options.
Remember: backups are your best defense and strong security habits will keep you safe. Stay safe, stay prepared, and never underestimate the value of your data.
