My Avast has detected a infection on my system


OS: Mac OSX Mavericks 10.9.3


Infection: JS:Pdfka-ADK[Expl]


File: /Users/username/Library/Caches/TemporaryItems/plugtmp/plugin-pagespeed.js


Process: /Applications/Firefox.app/Contents/MacOS/firefox


UID: 502


Its the first time that the Avast found a malware directly in the Firefox.app


I went to the folder in the finder

but found no files of that name. however, when I was closing the browser saw the file appear for a split second before  disappearing.


Update 12 Jun 12:06 (GMT)

 I have found the file in the "History" of "File System Shied" , I have the option to "Submit to virus lab" or to copy path or clear history.


from what I have found its to do with a Java script called Page-Speed, so does it mean a

false positive?


What should I do next?

Has your problem been solved? How? My Avast also pops up with a threat detected with "JS:Pdfka-ADK [Expl]" on the bottom.

Have you solved your problem? I recommended please remove Avast because they have many false positives on the mac. Don't let Avast delete any files this will damage your system.


The detected "JS:Pdfka-ADK [Expl]" is an javascript I belivieve has to do with Adobe Reader.


For Instructions to remove Avast look at his Forum there: https://forum.avast....p?topic=32538.0
