Thank you for your response. I can certainly understand your frustration. I don't know what sites you previously visited or the qualifications of the persons who provided you with advice.
Here, at BleepingComputer, only fully qualified Malware Removal Team (MRT) members are permitted to deal with FRST logs. They have extensive training (it takes a year plus, normally, to gain an MRT designation here at BC). I started my studies in April and I don't expect to "graduate" until late in 2016. That is how intensive the training is here.
I did not ask you to connect your computer to any networks. My suggestion was that you download the FRST tool from here
and run it, if you can. Some malware will prevent FRST from running, in which case, please get back to me and we will explore alternative options.
By doing as I suggested, and pasting the FRST scan results in the Virus/Trojan//Spyware and Malware Removal Logs
Forum, you do not risk any possible infection to the your external DVD drive. The MRT member, who analyses your log, will determine what malware is present and whether it can be removed. The success rate here is pretty phenomenal in removing malware.
That said, it is YOUR computer. Do what you are comfortable with. The Bleeping Computer community is here to assist you, and others, with the entire gamut of computer problems.
I do hope that you will take my advice and submit an FRST log so that we here, at Bleeping Computer, can try to help you.
Thank you for posting, and replying. Your call. Have a great day.
