How to Remove LockLizard, Avast JS Redirector Trojan

As a website owner, it's crucial to stay vigilant and keep an eye on your online presence. Recently, I encountered an issue that made me realize the importance of having robust antivirus software installed on my computer. When I looked at my website's header, I found a suspicious script that hinted at a possible infection.

After conducting a thorough scan with Avast and Malwarebytes, I was surprised to find no threats detected. However, when I tried to access my website, Avast issued a warning, stating that it had blocked the site due to suspected viruses. This raised concerns about whether everything was truly detected and removed.

To better understand the situation, it's essential to have Avast installed on your computer. If you're experiencing similar issues, follow these steps to remove the LockLizard, Avast JS Redirector Trojan:

1. Perform a full scan: Run a comprehensive scan with Avast and Malwarebytes to ensure that all potential threats are detected.

2. Upload to Virus Total: After completing the scan, upload your website's files to Virus Total for further analysis.

3. Add exceptions in Avast: Create a temporary folder (e.g., Temp-Quarantine) and add the extracted file to it. Then, go to Quarantine, hover over the entry, and select 'Extract' instead of 'Restore' or 'Add exception.'

4. Monitor your website's behavior: Keep an eye on your website's behavior, as this Trojan may try to re-infect your pages within a short period (usually 6 hours).

5. Change FTP-server password: To prevent re-infection, change the FTP-server password immediately.

It's also worth noting that the JavaScript trojan may be injected into an HTML page via an SQL injection attack or present on a malicious website, redirecting users to unexpected sites. Be cautious when interacting with suspicious websites and keep your antivirus software up-to-date.

By following these steps and taking proactive measures to secure your online presence, you can effectively remove the LockLizard, Avast JS Redirector Trojan from your website and prevent future infections.
