Windows 7: Malwarebytes ioser12.dll False Positive?

Malwarebytes ioser12.dll False Positive?

I Just ran a malwarebytes scan under Seven and it discovered a 'Trojan.Downloader' - ioser12.dll - on my Vista drive in the Java folder:

Malwarebytes ioser12.dll False Positive?-falsepositive..jpg

ioser12.dll properties:
Name:  ioser12.JPG
Views: 59
Size:  58.9 KB

Is it safe to assume that it's a false positive?

(I know the second entry is)

It's a legit java file. I checked it mine with 40 different Av, checks out ok, and Malwarebytes didn't detect anything with a full scan. If you're worried, get rid of your java, re download it form the site, scan again.

I think I'll just boot into Vista, uninstall, update and if it shows again I think I'll have a definitive answer.

BTW... Java is update 13 now.
This is the best way to install it:
  • Download the latest version of Java Runtime Environment (JRE) 6.
  • Scroll down to where it says "Java Runtime Environment (JRE) 6u13 allows end-users to run Java applications".
  • 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 with or without 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.
  • 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-6u13-windows-i586-p.exe to install the newest version.

lol, yeah I'm crippled with just the one

I've always been slack about updating Java.

Well, removed all existing Java, updated to 13 offline, scanned again and it wasn't flagged this time. Either way, it's all good now

Odd thing though, java is no longer appearing in add/remove panel

Hi SE,

That's good news, except about not being in the control panel. You know you can d/l both 32 and 64 bit java on the same OS. Just a little something I thought I'd throw in there.
