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"

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...
