why are there viruses even in a DVD/CD disc?


ronnieu,answering to comments
Last week, I downloaded many software from the Internet, and all scanned with no viruses or spyware, .. then burned onto a DVD for a backup ... but today when I tried to use this software from disk software have been infected by the virus ...

It was ok last week, but today, with many viruses ... and I know that my PC is immune to the virus after scanning twice, except in the hard ... why are there virus in a single disk?
I can only give you a scenario on a virus that works ...... Viruses are programs that can run itself automatically ... until this is not fiddled ...... or enforced in your case ... .. it seems that had no effect on the files (. exe) until they fiddled with your antivirus program .... once those files controlled by your antivirus .... the virus in memory (as in the process memory) made these files ...... as you told me that it is now detect the virus .......



On other scenario, as you told me that you have downloaded files on the Internet and then scanned at the time ...... not found any viruses ...... Now your antivirus software is updated automatically and new viruses definations in cases provided for your antivirus program .... and now when one runs the scanner new viruses that the cases detected by your antivirus last time was detected after updation ............... this is not your case was infected at that time ... it is .... but it has not been detected ...... I think I've made clear to you ....... I do hope .... ;) ......

sometimes the virus does not recognize the software and the names of a virus. Sometimes the virus is correct and it is a virus, but sometimes it is right to be cautious and reads like a virus.



To be sure, you probably should instruct your disk to another computer with protection against viruses, scan and see if it reads as a virus. If it does not suit you, it may mount your hard drive.
