I'm not sure if this is an ESS issue, a Vista issue, a malware issue, or some combination of them. But maybe someone else has seen this and has some thoughts or can point me where to find answers. Running Vista 32 bit. Standard Allow firewall rule is set for IE. IE is set as a web browser and in active mode in ESS settings. I go a few weeks using IE with no problems. Then out of the blue one day I go to open IE from the desktop and ESS pops up an outbound firewall alert. Seems odd since I already had a rule for IE, but I set the rule for allow / remember. In looking into the matter, I go into Windows Task manager - Processes tab. I right click on iexplorer.exe and choose to open file location. Low and behold IE is running from the C:\Windows\winsxs folder. Usually iexplorer.exe runs from the C:\Program Files\Internet Explorer folder. From that point forward, no matter what I click on to open Internet Explorer, it opens from the winsxs folder. And supposedly the winsxs folder is where previous versions of software are kept. I will say, had I not gotten the outbound ESS alert I might not ever have noticed anything wrong. Internet Explorer still works and functions fine. I would like to know what is causing Internet Explorer to run from a backup location out of the blue. Vista error, malware, ESS issue? If anyone else has noticed this - can be checked from Task Manager, or if anyone has thoughts on this, please give a shout.
