My Trend Micro ran it's weekly scan and found a virus: 5a5ef45b-3194e33a (a.k.a. LohanuF.class)

It was found in: AppData\LocalLow\Sun\Java\Deployment\cache\6.0\27

Trend Micro qurantined it, but I want to know if my computer is still infected. Or if it was a 'false positive', or if I need to take further action. According to T.M. I do not need to do anything else. I can delete the quarantined file if I want, but if I do that, will I screw up my computer?

Help, please.

Thanks! :thumbsup:

Are you experiencing any issues with the computer? Have you scanned with other security tools?

A couple things to do as a precaution:

Clear the Java cache:
  • Go to Start -> Control Panel.
  • In the Control Panel, double-click the Java icon.
    • The Java Control Panel appears.
  • Click Settings... under "Temporary Internet Files".The Temporary Files Settings dialog box appears.
  • Click Delete Files...The Delete Temporary Files dialog box appears.
  • Click OK on the Delete Temporary Files window.
    NOTE: This deletes all the Downloaded Applications and Applets from the cache!
  • Click OK on the Temporary Files Settings window.
  • Close the Java Control Panel.

    You can also view these instructions along with screenshots here.
2] Older version of Java are a security concern. You need to make sure your Java is up to date and that old versions are removed.

Older versions have vulnerabilities that malicious sites can use to exploit and infect your system. Please follow these steps to remove older version Java components and update:
  • Download the latest version of Java Runtime Environment (JRE) Version 6 and save it to your desktop.
  • Look for "JDK 6 Update 18 (JDK or JRE)".
  • Click the "Download JRE" button to the right.
  • Select your Platform: "Windows".
  • Select your Language: "Multi-language".
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
  • Click Continue and the page will refresh.
  • Under Required Files, check the box for Windows Offline Installation, click the link below it and save the file to your desktop.
  • Close any programs you may have running - especially your web browser.
Go to Start > Settings > Control Panel, double-click on Add/Remove Programs and remove all older versions of Java.
  • Check (highlight) any item with Java Runtime Environment (JRE or J2SE) in the name.
  • Click the Remove or Change/Remove button and follow the onscreen instructions for the Java uninstaller.
  • Repeat as many times as necessary to remove each Java versions.
  • Reboot your computer once all Java components are removed.
  • Then from your desktop double-click on jre-6u18-windows-i586.exe to install the newest version.
  • If using Windows Vista and the installer refuses to launch due to insufficient user permissions, then Run As Administrator.
  • When the Java Setup - Welcome window opens, click the Install > button.
  • If offered to install a Toolbar, just uncheck the box before continuing unless you want it.
-- Starting with Java 6u10, the uninstaller incorporated in each new release uses Enhanced Auto update to automatically remove the previous version when updating to a later update release. It will not remove older versions, so they will need to be removed manually.
-- Java is updated frequently. If you want to be automatically notified of future updates, just turn on the Java Automatic Update feature and you will not have to remember to update when Java releases a new version.

Note: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications. To disable the JQS service if you don't want to use it, go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter. Click Ok and reboot your computer.
