I use the digital signature feature to sign tax returns that I prepare. I have used this feature for a couple of years and find it most useful. Suddenly, when I try to use this feature and go to 'Sign As:', I get literally dozens of .com addresses, but not my name as I had originally set it up. Also, the message 'Certificate Issuer: DO_NOT_TRUST_ FiddlerRoot'. Does anyone use this feature, and have any ideas about how to correct this problem ?
Can you post a screen shot of what you're seeing?
Apparently these DO_NOT_TRUST_ FiddlerRoot certificates come from adware/malware. You should get rid of them.
Fiddler generates certificates to manage Web traffic it monitors and places them in the Personal section of the Windows Certificate Store. This is not malware if you are using Fiddler, just a side-effect. I prefer to place my Digital IDs in the Acrobat Store (aka Digital IDs and Trusted Identities). SO, perhaps you should do the same.
