Scan Windows computers on demand to detect and remove existing malware alongside ongoing antivirus protection.

## Check for existing infections with iolo Malware Killer

iolo Malware Killer is an on-demand malware detection and removal tool for Windows. Its role is to investigate threats already present on a computer, complementing the ongoing protection provided by an antivirus application.

Use a scan when investigating unexpected pop-ups, browser changes or other suspicious behavior. Those symptoms can have different causes, so review the scan findings rather than assuming that every slowdown indicates an infection.

## Analyze suspicious files with evolving detection

The detection approach combines a threat-analysis algorithm, machine learning and a growing reputation database to assess suspicious files. It is designed to recognize emerging threats as well as known malware.

These methods describe how the product evaluates threats; they do not guarantee that every malicious file will be found. Detection speed and scan duration depend on the computer, the items examined and the current threat information.

## Review detections and the result of removal

Allow the scan to finish and inspect the reported items before acting on the findings. Note the affected file or application and follow the available removal workflow in the installed release.

After completing the recommended actions, check whether the original behavior has stopped and review any remaining alerts. A completed scan is a result to assess, rather than proof that every possible compromise has been resolved.

## Keep on-demand cleanup alongside ongoing protection

Malware Killer focuses on finding and removing existing infections. That task differs from continuously checking files and activity as you use the computer. Review your active antivirus protection separately.

Our [antivirus software catalog](https://find-your-software.com/products/antivirus.html) covers other protection options. For an alternative with documented real-time malware controls, explore [IObit Malware Fighter Pro](https://find-your-software.com/iobit/malware-fighter-pro/) and review the selected edition.

## Understand the shared installer and activation

Malware Killer uses the System Mechanic Ultimate Defense installation framework. A standalone installation can initially display that suite name; entering a Malware Killer activation key enables the corresponding product.

The installer name does not establish access to every component of the suite. Check the activated product and available tools before following instructions intended for another iolo edition.

## Separate malware removal from maintenance and recovery

For supported application and driver updates, see [iolo Updater](https://find-your-software.com/iolo/updater/). For cookie cleanup and browser privacy settings, explore [iolo Privacy Guardian](https://find-your-software.com/iolo/privacy-guardian/). These tasks address different issues from removing malicious software.

Malware removal does not recreate files already lost or damaged. Maintain independent copies of important data using a suitable [file backup workflow](https://find-your-software.com/solutions/how-to-backup-files.html).

## iolo Malware Killer FAQ

### What is iolo Malware Killer used for?

It scans Windows computers on demand to find and remove existing malware.

### Does it replace ongoing antivirus protection?

Its documented role is on-demand detection and removal. Keep active antivirus protection in place and review that application's status separately.

### Can it detect previously unknown threats?

iolo describes analysis and machine-learning methods intended to identify emerging threats. This is a detection capability, rather than a guarantee that every new threat will be found.

### Do pop-ups or slow performance prove that I have malware?

No. These symptoms can have several causes. Use scan results and the affected application's behavior to guide further investigation.

### Why does the installer show System Mechanic Ultimate Defense?

The products share an installation framework. Your Malware Killer activation key enables the corresponding product without granting every suite component.

### Does removing malware restore damaged files?

Do not rely on removal to reconstruct damaged or missing data. Recovery from an independent backup is a separate task.

### Does a clean scan guarantee that the computer is secure?

No. Review remaining symptoms and alerts, keep protection updated and investigate unresolved behavior after the scan.
