JRiver version 21.0019 alert
« on: November 10, 2015, 03:14:56 pm »

I updated JRiver to newest build yesterday. FSecure antivirusprogram found a trojan in the jr21.exe file. It removed the trojan and also JRiver program. I have downloaded and installed JRiver twice since. Both times the same happened: removal of the trojan and the jriver program. So now it seems that I have a collection of more than 80000 audio files, but no software to play them.

Re: JRiver version 21.0019 contains a trojan

We check every version we release for viruses or trojans quite carefully just to be sure, so we can say with quite some certainty that our software is fine.

Note that we do not have something called a "jr21.exe"

Tell your antivirus provider that it found a false positive.

You can report False Positives to F-Secure here:
https://analysis.f-secure.com/portal/login.html

Until they fix their database, you can exclude Media Center from their scans using these instructions:
https://community.f-secure.com/t5/Security-for-PC/How-can-I-exclude-an-application/ta-p/15400

If it is throwing up the error when you are installing MC, and preventing you from installing it, you'd need to exclude the installer executable (and not MC itself).  If it is throwing up the error after MC is installed, when you are trying to use it (or just on its own when it runs a background scan) then you need to exclude whatever it is tripping up over.

While you are at it, though, you may want to read through the this article and look at the Taming Your Anti-Virus examples provided for Windows Defender or Symantec Endpoint Protection:
http://wiki.jriver.com/index.php/Troubleshooting_Security_Software

You can probably improve the performance of Media Center by following some of those tips.  In particular, excluding MC's running processes and your Library disk location can make substantial improvements in responsiveness. There's no article there specifically for F-Secure, but using the instructions from them linked above and referring to the other examples should get you through.

If you're having no other issues this isn't required, but if you feel like MC is slow in a few places, the issue very well might be F-Secure interfering. This isn't necessarily anything bad about F-Secure, by the way. That's just part of the deal. The way AV applications work is by intercepting all disk accesses (and often memory accesses too) and re-routing them through themselves. This necessarily causes a loss of performance by its very nature (there is more work to do on every disk and memory access). It can also introduce bugs or other unexpected behaviors, because they are changing the way the OS works at a fundamental level and routing everything through their own code.

Hello Everybody,

Maybe you already know, but anyway: About an hour ago I reported the "F-Secure Trojan-Alert" regarding MC 21.0.19 to F-Secure and I have just received the following confirmation from F-Secure: "The file you submitted is clean. It will be added into white-list." So hopefully our problem is solved with a new (automatic) update from F-Secure.

Best regards to all of you  :)

Hello Everybody,

This is just to let you know that right now I can run a manually F-Secure scan on 'Media Center 21.exe" without any warnings or alerts. So I think that F-Secure's databases have been updated properly.

Best regards  :)

Hello rs57 (and others who maybe have faced this specific problem with F-Secure),

This is a follow up on my 2 posts on the problem with F-Secure reporting "Trojans" in MC 21.0.19.

All your music files should still be in place untouched, unless you did something else. It is "only" the file 'Media Center 21.exe' that has been removed, and the best way to get back on the track is to "reinstall" using the MC 21 install file from this site. Do not change anything during the installation as JRiver MC 21 will adapt you existing settings.

I used this method and right now MC 21.0.19 is working secure and exactly as we are used to :)

Best regards,

Peter DK
