Please show me some way for how to remove Exploit.JS.PDF.D?
Actually Exploit.JS.PDF.D is a virus that is being contained in a PDF files. The name of exploit itself says that it is virus related to the pdf files. I think the external drive which you have connected with your computer must be containing some infected pdf files from which it came to your computer. Do not be worrying as this virus does not affect your computer as long as you do not open that pdf file.
It may happen that you have downloaded some pdf file from the internet or which came to your inbox as an attachment to the mail and you just click on it. I would like to inform you that downloading an attachments given from the unknown users should never opened as it could contain any malicious data which can make your computer's condition serious. Today many company sends their pdf forms in an email attachments but beware of opening those.

If your computer got infected by the viruses then it may happen that those virus have disabled your anti virus system so that it can not be detected by it. I would like to suggest you to make sure that your computer has enabled firewall or not because firewall play important role in security of computer system as it is a gateway from which every bits of data passes through. Go to the Network And Security from the control panel and check for the option enabling the firewall.
If your computer contains the Exploit.JS.PDF.D then it passes parameters to "Collab.collectEmailInfo()" function and then executing a specific shellcode. in order to exploits a buffer overflow vulnerability in the Adobe PDF reader JavaScript engine. This shellcode in further could be able to download and execute an arbitrary piece of malware.
