Kaspersky Virus Removal Tool how to Use

Download the executable, launch it, and click the Scan button—that's how to use the kaspersky virus removal tool how to use in its most basic form. Version 20.0.12.0 works as a standalone portable virus scanner, meaning no installation required and no conflicts with your existing antivirus software.

Getting Started with the Scanner

The interface loads immediately after execution. You'll see three scan options: Quick Scan (checks system memory and critical Windows folders), Full Scan (examines your entire drive), and Custom Scan (lets you pick specific folders or drives). Most infected systems benefit from a Full Scan, which typically takes 30–90 minutes depending on drive size and file count.

Before scanning, update the virus definitions. The tool checks automatically on launch, but you can manually refresh by clicking the Update button. This ensures detection of the latest malware threats rather than relying on bundled definitions from months prior.

Running a Complete Malware Removal

Start with Full Scan. The progress bar displays real-time statistics: files checked, threats found, threats neutralized. When threats appear, the tool quarantines them automatically—you don't need to intervene. Quarantine isolates suspicious files so they can't execute while you decide whether to delete them permanently.

After the scan completes, review the Results window. It lists each detected threat by type (trojan, adware, potentially unwanted program). You can export results as a text file for records. Then select "Remove All" to delete quarantined items, or right-click individual entries to restore them if a false positive occurred.

The tool works on Windows 7 through Windows 11, both 32-bit and 64-bit systems. It handles ransomware, spyware, rootkits, and browser hijackers—not just viruses. This malware removal tool approach differs from 360 Total Security's continuous monitoring, which runs in the background. Here, you control when scanning happens.

Using It Offline and on Compromised Systems

The offline antivirus scanner feature proves invaluable for severely infected machines that won't boot normally. You can place the executable on a USB drive from another computer, boot the infected system into Safe Mode, and run scans from the external drive. This bypasses malware that might interfere with full Windows startup.

For maximum protection on infected systems, boot from a Windows installation media, access the command line, and navigate to your USB drive to launch the scanner. This method prevents active malware from hiding files or blocking detection.

Cost and Limitations

It's completely free—no paid tier, no trial period expiration, no nag screens. Kaspersky offers this portable virus scanner as a supplementary tool alongside their commercial Kaspersky free antivirus products.

The main limitation: it's a scanner, not a real-time guard. It won't protect you during normal browsing—you still need dedicated antivirus software running in the background. Think of it as a second opinion tool, similar to AdwCleaner's focused approach to PUP removal.

It also can't restore files encrypted by ransomware. Recovery requires backups or specialized decryption tools specific to the ransomware variant.

When to Deploy This Tool

Use it for periodic deep scans, emergency malware removal, or when you suspect infection but your primary antivirus missed threats. Learn about kaspersky virus removal tool how to use by treating it as a supplementary defense layer rather than your main protection.
