Windows Defender Reporting Eclipse JAR as Infected

Posted by Jeff Ledbetter on 06-Dec-2016 18:37

Hi.

Today Windows Defender (Windows 10) started complaining about this file (and it's counterpart in my generic Eclipse installation):

C:\dlc\11.6\oeide\eclipse\plugins\org.eclipse.wst.server.ui_1.4.104.v20130830_1134.jar

claiming it be infected: Trojan:Win32/Detplock.

Has anyone else experienced?

Hi Jeff,

Windows 10 (14971)

11.6.2 64-bit

Defender definitions up to date

That file scans clean for me.

file info:

org.eclipse.wst.server.ui_1.4.104.v20130830_1134.jar

MD5 hash: 3fca803a254d8cc3a7f8f79bb04cac39

SHA1 hash: d4cc54178ed717c65c3d9113cb3625c3c64915ad

size: 857,109 bytes

Hope this helps.

I checked another machine with 11.6.3 64-bit.  Same file size and hashes.  Scans clean with Kaspersky.

File hashes are from Microsoft File Checksum Integrity Verifier.

Ahh.. just saw this on the MS info page about this threat:
