Jpegdds.dll quarantined as malware

I’m using an older Lenovo laptop running Windows 10 as a Roon remote and endpoint that connects to a Core on a different computer. Previously album art was extremely slow to load to the point of being unusable. After searching the Roon Community I saw that some people solved this by installing the 32 bit version of Roon. I uninstalled the 64 bit version, then downloaded and installed the 32 bit version.

Now Roon won’t launch because Malwarebytes quarantines jpegdds.dll as a malware threat. My other computer runs the 64 bit version, which also contains jpegdds.dll, without any problem from Malwarebytes.

Can anyone answer why this file triggers a security threat on the 32 bit version and not on the 64 bit version of Roon for Windows? How do I know if it’s safe to whitelist jpegdds.dll?

Different binaries different digital signature … suspect only Malware Bytes can answer. Give the a ping they are usually responsive.

You don’t, you have to make a judgment …

  • It’s part of an official commercial download from a known vendor.
  • Google search, look for issues.
  • Ping Malware Bytes, as them to double check the file.
  • The likelihood is that’s a false positive.

Before Malware Bytes fix their issue, can you not add it to an exception/no scan list to get you up and running?

Just updated to 1.8 build 814. No problem running the 64 bit version. The 32 bit version wouldn’t run because Malwarebytes quarantined three files: RAATServer.exe, Roon.Media.dll and (again) jpegdds.dll. Whitelisting Roon.Media.dll didn’t work because the Malwarebytes AI engine continued to re-quarantine it as an zero-day threat, so I had to whitelist the entire C:\Users\userName\AppData\Local\Roon\Application\100800814 folder.

It’s a pain in the butt if I have to go hunting around to whitelist files for every build update. Plus I don’t love the idea of whitelisting an entire folder without knowing for certain if there might be malware. I trust Roon Labs, but recent experience shows it’s possible for malicious code to sneak into anybody’s software. Nobody has complete control over the whole chain of source code.
