Hi, I'm new to this site but maybe you could help me out!

When I installed Cubase SXv3.1 my anti-virus software (Command AntiVirus) told me it could not disinfect the above virus. The location was C:\Program Files\Synchrosoft\POS\H20\emu.dll. After doing some research I found that this is likely to be a false-positive (which I assume means not really a threat) and is actually part of Cubase.

Anyway, I uninstalled Cubase and that particular problem seemed to go away. But now Command AntiVirus (which by the way is the anti-virus software our company uses, hence it is free for me to use at home) finds what seems to be the same virus but in a different location C:\System Volume Information\_Restore{094ED2EF-B4C2-48FA-B681-1FACB529B5DF}\PR471\A0039131.dll. A few days ago in the same location the dll file that Command was finding was called A0038992.dll.

I have been through all the steps on your help page (ie Ad-Aware, Spybot, McAfee Stinger) and have installed ZoneLabs Zone Alarm (previously I only had Windows Defender.)

Is this also a false positive or should I be worried? Any help would be much appreciated!

Hi,

When I installed Cubase SXv3.1 my anti-virus software (Command AntiVirus) told me it could not disinfect the above virus. The location was C:\Program Files\Synchrosoft\POS\H20\emu.dll. After doing some research I found that this is likely to be a false-positive (which I assume means not really a threat) and is actually part of Cubase.

This is indeed a false positive, so it may be a good idea to reinstall Cubase SXv3.1 again, let it ignore the emu.dll and send a sample of the emu.dll to Command Antivirus.

What's in your C:\System Volume Information are actually your system restore points, so a system restore point was made when Cubase was still installed and that explains why your Command Antivirus finds that file there as well.
You can just flush your system restore points by disabling system restore, then reboot and then re-enable system restore. This will remove all previous system restore points and then a new one will get created.

As a sidenote, Your version of Java is outdated and needs to be updated to take advantage of fixes that have eliminated security vulnerabilities.
Updating Java:
  • Download the latest version of Java Runtime Environment (JRE) 6u1.
  • Scroll down to where it says "Java Runtime Environment (JRE) 6u1".
  • Click the "Download" button to the right.
  • Check the box that says: "Accept License Agreement".
  • The page will refresh.
  • Click on the link to download Windows Offline Installation, Multi-language and save to your desktop.
  • Close any programs you may have running - especially your web browser.
  • Go to Start > Control Panel double-click on Add/Remove programs and remove all older versions of Java.
  • Check any item with Java Runtime Environment (JRE or J2SE) in the name.
    - Examples of older versions in Add or Remove Programs:
    • Java 2 Runtime Environment, SE v1.4.2
    • J2SE Runtime Environment 5.0
    • J2SE Runtime Environment 5.0 Update 6
  • Click the Remove or Change/Remove button.
  • 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-6-windows-i586.exe to install the newest version.
