Scan iso for virus software#

Many software companies do publish the SHA1 or MD5 value on their download pages, but Microsoft does not.

Unfortunately, Microsoft does not publish the SHA1 and/or MD5 sums on their websites so you are left with only the option of comparing those values with others that have downloaded the ISO file as well. The way to tell if the ISO file has been changed or is corrupted is to use the program to calculate the SHA1 and/or MD5 sums of the ISO file. So what you are ultimately left with is pretty much trusting the first and second statements that there is very little chance that you are downloading an already infected ISO file from Microsoft and there is very little chance of that ISO file getting infected sitting on your computer - even if your computer is infected itself. There is no anti-virus/anti-malware program that is going to catch 100% of all viruses/malware. I don't know of any way of making sure that you see every file contained in the ISO. When you mount or extract an ISO file or burn a DVD/USB/CD from it, it is possible for there to be hidden files. If the virus tried to insert itself directly into the ISO file without extracting everything first all it would do is corrupt the ISO file and cause it to fail to open/extract and you would just get an error that the file could not be opened. A virus cannot simply alter the ISO file itself to insert the virus - it would actually have to extract the over 3GB file somewhere, insert the virus into an executable file extracted from the ISO - and then recreate the ISO file from all the files previously extracted. The reason is because the ISO file is an image. Second - The chance that your computer would insert the virus into the ISO file after downloading is also next to zero. Either Microsoft would have to post the ISO file with the virus already in it (so how much do you trust Microsoft?) or your computer would have to insert the virus after it was downloaded.

First - the chance that you have a virus inside an ISO file that you download directly from Microsoft is next to zero.
