Avast pops up a warning about JS:Pdfks-gen when I “print” a 3d-pdf from my cad-program MicroStation. When I print a normal pdf Avast i silent.
Exploit have been blocked.
Everything else seems normal on the computer.
Can it be false positive - and how can I detect that?
Any help is much appreciated.
run hjt and post the log in your next reply
bare my ignorance - hjt, what is that?

you be the judge of dgdersvc.exe www.registrygenius.com/exe-errors/dgdersvc.exe.html
there shouldnt be so many missing files either
Run HJT again and be sure to only check the box beside entries with this at the end … (file missing) … as they are useless without a file.
See the links below for information about dgdersvc.exe as it should be safe and may be a part of the computer manufactor’s installation.

It is a short list and that is good.
It was actually JS:Pdfka-gen [Expl] - or this is at least what Avast says now.
ANd I have some pretty important stuff to do tomorrow, so I will wait with any fixes until I can handle a crash of my computer. I’ll be back in a day or two.
Thanks for your help so far.
When you get back, let us know if there is anything in Avast Virus Chest
Got the below
Hello,
Thanks for sample.
Our virus specialists have been working on the problem and our virus definitions have now been updated.
If you need further assistance, don’t hesitate to contact me again.

Switched on scanning of pdfs > no reaction from Avast any more.
Thanks to everybody that helped.

You are welcome, Thomasp, as I am glad to have helped in some small way. 
skype could be suspicious because its used by millions of people. that being said, creators of viruses could change the program and make it malicious. but then again it might also be clean
