I run windows XP. 2-3 weeks ago I began receiving notification of a "Run As" dialog box with no indication of what software I was being asked to run. Assuming it to be a virus or malware I did not run it but canceled. They (sometimes more than one) show up at indeterminate times. I run Sophos AV and Max Secure spyware. All show up with no problems. I then uninstalled Sophos and installed Trend Micro. This showed up some issues. None according to online look ups that could cause this. Looking on line I have found no connection to virus and Malware and this dialog box. Currently I am thinking that perhaps some logging software may help to determine what software or whatever is bringing up this box. Suggestions or has anyone heard of this?
