Toss the CD back at the supplier like a slap in the face.

I'm serious. The supplier needs to rectify this NOW. Not later. The sooner they know, the sooner you'll get a good CD.

Please share supplier and title of the CD so we can avoid it too.

Once a CD-R is burned, the data's there for good since unlike a CD-RW, you can not erase any portion or the entire CD's contents. Hence, it is impossible to remove the virus from the disk. Now comes the question where the virus came from. Since you say it is a CD of software downloaded from the internet, I'm assuming it's on that your friend made, and not a company. In that case, we take the question further, to what programs they are (name them) and where they came from (what was his/her source?). We come down to several possibilities:

* These programs are natively bundled with malware. (We can point you to alternatives.)
* They are downloaded from a shifty source. (We can direct you to a safe download site.)
* These programs are pirated and from P2P networks. (Their existance and use is illegal, meaning you'll receive no support.)
* The programs are fine, but your friend was infected and a copy of the virus was transferred to the CD. (He may need help cleaning his computer.)

In any case, I'd destroy the CD immediately, as it's much more trouble than it's worth. Either download clean copies yourself, or if you're restricted by dial-up internet access, have your friend create a new CD with clean copies of the legal software.

Hope this helps,
John

It'll probably remain unknown...

By copying the CD to your computer you will most likely be unleasing it on your system if you haven't already. (Hopefully Norton blocked everything successfully. Another question...what do you do about spyware, something Norton does not detect well?) Thus, this is not the preferred method.

Without details, this problem will most likely forever remain a mystery:

* You gave us no information about your computer, operating system, etc.
* If you cannot copy from source, the CD is either DOA or copy protected. Either way, you're out of luck...a damaged/faulty CD must be replaced, and a copy-protected CD cannot be legally copied. Thus, we need to know who burned it and with what.
* We don't know what viri were reported...viri names and file locations are important.
* We have no clue what these programs are, so it's possible that they are in fact viri, bundled with viri, etc.

If you provide the requested information we may be able to assist you. However, with little to go on there's little help that can be provided.

Give a shout back.
John
