Last night I received an AVG Resident Shield warning that Astroplanner.exe contained a trojan (this has never happened before and there had been no updates as I was not connected to the internet). Astroplanner was not running. Selecting the heal option the message came back, Heal successful (or some such thing).
Then about half an hour ago I noticed my Astroplanner Icons had changed to the boring windows generic "I don't know what this is so I'll put this icon to it". When I clicked on the icon to open Astroplanner nothing happened. So I went and check the program folder and there was no Astroplanner.exe there

Damn. So I thought I'd reinstall it. Up pops the AVG Resident Shield warning that D:/windowsintall.exe has the Trojan horse Dropper.Agent.FCB. In fact the installer icon on the CD is the same boring windows standard one as well. When I click ignore I get "Windows cannot access the specified device, path or file. You may not have the appropriate permission to access the item." Even if I turn AVG off I still can't access it.
Not only can I not install it again, I can't even find the program under control panel "Add Remove Programs" to completely remove it and start again.
Can anyone give me any ideas how to fix this problem
Thanks
