How to remove JS:Pdfka-ADK [Expl]

All of a sudden, my Avast Antivirus went berserk and keeps on showing an alert about JS:Pdfka-ADK [Expl]. I never download neither change any settings on the PC so I am curious how this virus gets inside.

I did some research and found out that many people are searching for JS:Pdfka-ADK [Expl] removal. It fact, it both Mac and PC users are affected by this virus, as far as I can see. Some says that it has something to do with old versions of Java program. My Java is updated to the most recent version so I concur that JS:Pdfka-ADK [Expl] infection has nothing to do with outdated Java.

Some tech experts explain that it is an attack to vulnerabilities in PDF programs. I don’t have any PDF writer or reader on the PC so that statement is not confirmed.

Anyone here got some advice or proper ways to stop this JS:Pdfka-ADK [Expl] pop-up alert from the computer? Much more, if my PC is infected, I need some tools or scanners to get rid of this malware immediately.

    I think it came with my Adobe Reader update.

    I remove the Reader a few minutes ago.

    I’m curious to see if I still gets the Avast! warning.

    After removing Adobe reader I haven’t had any alerts since.
    But the bad news is my system froze, I had to do a forced shut down then the computer would not turn back on for several tries.

    It is working now, but I have no idea for how long.
