They say too much knowledge can be a dangerous thing. I'm probably living proof of that.. someone told me how to run a Microsoft diagnostic that shows which system files do not contain digital signatures. According to the scan, 35 of my files are suspect. Should I be concerned about this? I religiously scan for viruses, spyware and rootkits using three different apps for each. Everything is supposed to be okay. Here is the list of unsigned system files:

Re: System Files Not Digitally Signed

Hi TomGab and welcome to TSf ! :wave:

You don't have to worry about system files that are not digitally signed, it only means microsoft hasn't run extensive tests on them. The file owner (nvidia for most of your nvxxx.dll files for instance) will have tested them to make sure they would work fine with XP so you shouldn't have any problem.

Re: System Files Not Digitally Signed

justpassingby has hit it on the head (as usual) with his good advice. What I was told by a (major modem maker) rep who was in my shop one day was that Microsoft required some severe payments to (ie: test things that had already been tested by the company who produced the product) Microsoft to sign off and digitally sign the drivers. He said that several companies had enough of this open act of money grabbing, so therefore, they would not in the future be having their drivers digitally signed by Microsoft. Can't blame them for that, it is a rip-off.

Bottom line, if the machine works well with these, then it is not broken, so don't fix it by changing anything.

Re: System Files Not Digitally Signed

Thank you very much for the explanation, gentlemen. Bill Gates and money-squeezing go together like white on rice. I should have known!

Peace.

Gee, I didn't want to name names, but you got it right and I like the rice analogy. Anyhow, have a great day and don't be a stranger on our forum.
