Resolving an expired Microsoft Authenticode certificate on Windows 7?
I have a Windows 7 HP laptop and got a call from some Indian guy seemingly wanting to sell me some unneeded software or service. He had me pull up a cmd window, run certmgr and look at the Trusted Root Certificates to which I found 2 Microsoft certificates of Microsoft Corp and Microsoft Authenticode Root Authority had expired on 12/30/1999 and 12/31/1999 respectively. This was odd since most of other certs were all in valid dates. He claimed that my system had been hacked and that this was the result of the invasion.
Is his claim true?
Does Norton Internet Security check for these issues and how does one update the certificates to be valid?
My system was recently reinstalled in the last 2 months and is current with all important MS Updates.
