Why Is Malwarebytes Running Slow?
【📲 877 848 5082】 Malwarebytes is a security application that continuously performs tasks such as threat detection, protection, database updates, and scheduled scanning. Some of these operations can temporarily use more CPU, memory, disk, or network resources.
A slow Malwarebytes experience does not automatically mean that the application is malfunctioning.
The first step is to identify when the slowdown happens.
For example, Malwarebytes may feel slower while:
A scan is running
A large number of files are being examined
A Deep Scan is active
Malware is being detected or removed
Malwarebytes is updating
Another antivirus program is running at the same time
The computer has limited available memory
Malwarebytes VPN is affecting internet speed
Malwarebytes currently supports Windows 10 and 11 and recommends at least 4 GB of memory, with 8 GB preferred, for Windows devices.
Check Whether Malwarebytes Is Running a Scan
【📲 877 848 5082】 One of the simplest explanations for temporary slowdown is an active scan.
Malwarebytes provides several scan types, including Threat Scan, Custom Scan, Quick Scan, and Deep Scan on Windows. The amount of data examined varies by scan type.
A Deep Scan is particularly resource-intensive. Malwarebytes states that Deep Scans can affect device performance for a longer period because they use advanced detection techniques and more system resources.
If your computer becomes slow only while a Deep Scan is running, allow the scan to finish and then check whether normal performance returns.
For everyday checking, Malwarebytes recommends using Threat Scans unless there is a specific reason to scan a particular location with a Custom Scan.
Check CPU and Memory Usage
【📲 877 848 5082】 If Malwarebytes remains slow after a scan has finished, check your computer's resource usage.
On Windows, open Task Manager and look at:
CPU
Memory
Disk
Network
If Malwarebytes is temporarily using significant CPU while scanning, that can explain the slowdown.
However, if Malwarebytes continues consuming unusually high resources when no scan is running, investigate other possible causes instead of immediately disabling protection.
On Mac, Malwarebytes provides CPU settings that let you control how much processing power the application uses during a system scan. The available options are High, Medium, and Low. Malwarebytes notes that higher CPU usage can make scans faster but may negatively affect system performance, particularly on older devices.
Performance Troubleshooting Matrix
【📲 877 848 5082】 Use this matrix to identify the most likely cause before changing settings.
What You Notice | Possible Cause | What to Check | Recommended Action |
|---|---|---|---|
Computer slows during a scan | Resource-intensive scan | Scan type | Allow scan to finish |
High CPU during Deep Scan | Intensive detection process | CPU usage | Use Deep Scan only when appropriate |
Malwarebytes stays slow after scanning | System or software conflict | Task Manager / Activity Monitor | Check other applications |
Computer has low memory | Limited system resources | Installed RAM | Close unnecessary applications |
Internet becomes slow | Malwarebytes VPN | VPN status | Test with VPN off |
Another antivirus is installed | Security software conflict | Installed security apps | Review compatibility |
Malwarebytes will not update | Connection or software issue | Update status | Restart and check for updates |
Startup feels slow | Too many startup programs | Startup Applications | Review unnecessary startup apps |
【📲 877 848 5082】 The goal is to determine whether the slowdown is caused by Malwarebytes itself, another application, the computer's available resources, or a feature such as VPN.
Check for Another Antivirus Program
【📲 877 848 5082】 Running multiple security applications can create conflicts.
Malwarebytes says that having another antivirus application installed at the same time can lead to issues such as applications being blocked, internet problems, or other system problems. Malwarebytes recommends reviewing compatibility and using allow-list settings where appropriate.
If your computer has both Malwarebytes and another antivirus program actively protecting the system, check whether both applications are performing real-time security functions.
Do not randomly disable security software.
Instead, identify which applications are active and follow the supported compatibility instructions for the products involved.
Is Malwarebytes Making Your Internet Slow?
【📲 877 848 5082】 If by "slow" you mean webpages, downloads, or uploads are slower rather than the computer itself becoming sluggish, Malwarebytes VPN may be responsible.
Malwarebytes explains that VPN traffic is encrypted and routed through a VPN server, which can sometimes reduce internet speed.
To test this:
Check your current internet speed.
Turn the Malwarebytes VPN off temporarily.
Run the same speed test again.
Compare the results.
If the connection improves when the VPN is disabled, the issue may be related to the VPN connection rather than the Malwarebytes security scanner.
Malwarebytes also recommends trying a VPN server location closer to your physical location when VPN performance is slow.
Make Sure Malwarebytes Is Updated
【📲 877 848 5082】 An outdated application can cause problems that may disappear after updating.
On Windows, open Malwarebytes and select Settings. In the General settings area, check the application update options. Malwarebytes recommends leaving automatic application updates enabled.
If the application cannot update, restart the computer and try checking for updates again.
Malwarebytes says update problems can sometimes result from a VPN, proxy, third-party firewall, security application, or another configuration blocking communication with its servers.
Check Your Computer's Hardware
【📲 877 848 5082】 Malwarebytes cannot compensate for a computer that is already operating with very limited resources.
For Windows, Malwarebytes currently lists:
Windows 10 or Windows 11
At least 4 GB RAM
8 GB RAM preferred
At least 1 GB free disk space at installation
If your computer has limited RAM and several programs are open simultaneously, Malwarebytes may compete with those applications for available resources.
Close applications you are not using and check whether overall performance improves.
If Malwarebytes Is Still Slow
【📲 877 848 5082】 If the slowdown continues when Malwarebytes is not scanning, the computer meets the system requirements, and there is no obvious software conflict, continue troubleshooting rather than repeatedly reinstalling the application.
Check whether:
Malwarebytes is fully updated.
Windows or macOS is fully updated.
Another security application is active.
VPN or proxy software is running.
Disk usage is consistently high.
The computer has enough available memory.
The slowdown occurs only with a particular application.
If Malwarebytes is interfering with another program, Malwarebytes recommends temporarily quitting the application to test whether the other program works normally. This should only be done when you are certain the other software is safe, and protection should be restored afterward.
Could Malware Be Making the Computer Slow?
【📲 877 848 5082】 Sometimes the underlying problem is not Malwarebytes but an infection on the computer.
Malwarebytes lists reduced system speed, unexpected browser pop-ups, crashes, unexplained storage usage, changed settings, and encrypted files among possible signs of malware infection.
If you notice several of these symptoms together, run an appropriate Malwarebytes scan.
If suspicious behavior continues after scanning, Malwarebytes recommends creating a Support ticket and providing diagnostic logs so its Support team can investigate further.
