Suddenly one of Swift's standard library files is considered a bitcoin miner. Is it a false positive? File name is libswiftDispatch.dylib
Same issue: https://discussions.agilebits.com/discussion/86860/avg-quarantined-1password-libswiftdispatch-dylib

Same here with /Applications/Xcode.app/Contents/Frameworks/libswiftDispatch.dylib

I am having the same problem. I am getting an Infection blocked! message about every 10 seconds. From googling I saw a thread from one year ago that said this was a problem with an update/virus definition file. I look forward to a resolution to this one...
Thank you,
Tim

Same problem with
/System/Library/CoreServices/MRT.app/Contents/Frameworks/libswiftDispatch.dylib
-
I'm having the same problem. About every 10 seconds Avast is saying it has blocked a threat and moved it to the chest. libswiftDispatch.dylib
-
Same problem on my Macbook, Avast keep showing popups saying Infection blocked, file is libswiftDispatch.dylib
And I can't open my Telegram app too since it started :(
-
Same problem. This feels like a false positive.... but maybe not. Unfortunately, quarantining half a dozen program files makes it a bit hard to get work done with it locking away all these files.
-
Hello,
sorry for your inconvenience, we are working on fix and it will be release asap.
-
Same problem. Many libswiftDispatch.dylib alerts re MacOS:BitCoinMiner-AS [Trj], and some apps (e.g. Malwarebytes) now crash, presumably because various libswiftDispatch.dylib files, including some from CoreServices, have been moved to the Virus Chest.
This is a serious problem. Is it a real infection, or a false positive, and how will the problem be remedied?
-
This is incredibly frustrating, and basically unacceptable. libswift is used by Docker, Xcode, and a number of other development tools. I have half of my dev team unable to work until Avast stops quarantining software dependencies based on a false positive. This is the second false positive in a month that impact Xcode directly. I'll be actively migrating off of Avast after this..
-
I am experiencing the same problem (screenshot attached).
From the messages, the Avast team appears to be working on it, so hopefully a fix will be released soon.
Since this appears to be a false positive, is there any harm in removing the files from quarantine?
-
Meant release the files on my above post.

Meant release the files on my above post.
Well, l took a chance and restored the files (expect the latter 2, since it appears they re-generated so I deleted them).
-
The pop up warnings stopped, and my affected program works again. Thanks for fixing it.
-
Loosely related but I need this info to adress exactly this issue properly:
How can i find:
1. My current virus definition version + date of update
2. My current Avast app version + date of update
3. Newest virus definition version
4. Newest Avast app version

Right click the Avast sys tray icon and select "About Avast"

Same here not only affecting Xcode and CoreServices/MRT.app but any app that uses "libswiftDispatch.dylib"
-
Does anyone know the AVAST version number for mac computers that has the fix?
-
Apparently AVG had a fix this AM. What's the hold up Avast?
-
I was stupid enough to delete the libswiftDispatch.dylib file and now I can not get XCode to work properly even if I reinstall the program. Does anyone know How to get the file back?
-
So, I'm only just stumbling upon this thread because someone shared it over in the Apple forums. Admittedly, I never remember to conduct scans on my MacBook Pro and the other morning I got an alert that Avast blocked this very threat.
That prompted me to do a scan and I found this same Bitcoin Miner infection in Skype and here >> /System/Library/CoreServices/MRT.app/Contents/Frameworks/libswiftDispatch.dylib. Someone else posted finding it here as well.
Figuring the next move was to delete it, that's what I did. Skype stopped working and needed to be reinstalled. However, I haven't noticed any adverse effects from deleting that one mentioned above. Is there any concern in deleting it? Should I restore the file? I have no clue what it is! But obviously, I don't want to discover some sort of issue down the road...
