Does Malwarebytes free remove ransomware?

Ransomware is a type of malware that encrypts files on a device and demands payment in order to decrypt them. It has become an increasingly common cyberthreat in recent years. Malwarebytes is a popular anti-malware program that offers both free and premium versions. Many users wonder whether the free version of Malwarebytes can effectively detect and remove ransomware.

What is ransomware and how does it work?

Ransomware is a form of malware that locks access to a device or files until a ransom is paid. It encrypts files using complex algorithms so they cannot be accessed without a decryption key. Once files are encrypted, the ransomware displays a message demanding payment to receive the key. Payment is usually required in cryptocurrency, such as Bitcoin, to preserve the attacker’s anonymity.

There are several common vectors for ransomware infection:

– Phishing emails with infected attachments or links
– Compromised websites that download malware onto visitors’ devices
– Exploit kits that leverage software vulnerabilities to install malware
– Brute force attacks on systems with weak passwords
– Removable drives containing malware that execute on connection

Once installed, ransomware scans the system for files to encrypt. It targets documents, media files, databases and other important data. Network-connected drives and cloud storage may also be encrypted. The entire encryption process takes place in the background without the user’s knowledge.

When encryption is complete, the ransom demand is displayed. A countdown timer may threaten permanent loss of data if payment is not received in time. The ransom is often hundreds or thousands of dollars’ worth of cryptocurrency.

Even if paid, the decryption key is not guaranteed. Attackers may simply take the money without providing the key. Attempting to decrypt files without the key is extremely difficult if not impossible. This leaves victims with few options other than paying the ransom or losing their data.

What are the different types of ransomware?

There are several major families or types of ransomware, classified by their behavior and encryption methods:

– **Locker ransomware** simply locks users out of their devices without encrypting files. The screen is blocked, and payment is demanded to regain access.

– **Encryption ransomware** encrypts files so they cannot be opened without the decryption key. Common examples include WannaCry, CryptoLocker and Cerber.

– **Master Boot Record (MBR) ransomware** overwrites and encrypts the MBR section of a drive, blocking access to the operating system.

– **Scareware** pretends to encrypt files or block access while demanding payment, but does not actually cause damage.

– **Doxware** exfiltrates sensitive data from the system prior to encryption and threatens to publish the stolen data online if ransom is unpaid.

– **Ransomware-as-a-Service (RaaS)** provides ransomware toolkits and infrastructure that attackers can use to execute attacks with little malware expertise.

New ransomware families and variants emerge frequently as attackers refine their methods. Hybrid forms that combine multiple techniques are also growing more common.

How can you tell if your device is infected with ransomware?

There are several signs that may indicate a ransomware infection:

– Files becoming corrupted, inaccessible or renamed with strange extensions

– An encryption notice or ransom payment demand appearing on your screen

– Unusual disk activity during file encryption

– Inability to access system folders like Documents and Pictures

– Mapped network drives disconnected and unable to reconnect

– Being locked out of your system entirely and displayed a ransom message

– A ransom note such as DECRYPT-FILES.txt or instructions.txt on your desktop

– Strange new shortcuts appearing in your system startup folder

– Anti-virus software being disabled automatically

If you notice any of these warning signs, disconnect your system from networks and backups immediately. Isolating the infection prevents it from spreading. Do not pay the ransom until identifying the specific ransomware variant, as some decryption keys are publicly available.

What security measures prevent ransomware infections?

A combination of cybersecurity measures helps protect against ransomware infection:

– **Installing reputable antivirus software** that detects known ransomware variants. Use real-time scanning and behavior monitoring for full protection.

– **Applying software patches and updates** to eliminate vulnerabilities that are often exploited to deliver ransomware.

– **Using popup blockers** since ransomware is often spread through malicious ads and popups. Disable Flash, JavaScript, and unneeded extensions in your browser.

– **Exercising caution with email attachments and links**, which are common ransomware vectors. Never open attachments from unknown senders.

– **Backing up critical data regularly.** Maintain offline backups that are inaccessible to ransomware encryption. Test backups regularly for integrity.

– **Restricting administration rights** on end user systems to limit damage if an account is compromised.

– **Using firewalls** to block connections to known command and control servers used by ransomware groups.

– **Disabling RDP/remote access** when not absolutely required. Use VPNs with MFA for secure remote access.

– **Educating employees** to identify risks like phishing emails or malicious links. Human error is a major ransomware enabler.

A layered security approach provides overlapping protection to minimize gaps. However, ransomware is constantly adapting to new defenses, so continued vigilance is essential.

What is Malwarebytes?

Malwarebytes is an anti-malware software suite developed by the company Malwarebytes Inc. It provides virus protection, ransomware prevention, and other cybersecurity services for home and business users.
