Flash abominations and file permissions

I wrote a batch program called 'togflash' to toggle the renaming of the files that cause Flash animation to block my screen at times (GetFlash.exe,
Flash.ocx). So far, so good. I then discovered that the browser, finding them renamed, simply downloaded new copies and the awful visuals started up again. Wishing to extend my knowledge of Windows file permissions (that seem to be less intuitive than Unix ones) I decided to try the following:

1. Create a new account under Users. They are not meant to have file writing permissions in the directory these trojan files appear (C:\WINNT\system32\Macromed\Flash)

2. Run the browser as that user with 'Run as...'

Blow me if they're not *still* appearing. Why?

In your internet explorer security, set it to prompt you for active x controls and plugins rather than leaving it at 'enable'......or if you're sure you don't want to see them, set it to 'disabled'

Might be the browsing is down under "wimpy user" priveleges but the downloading is done through explorer.exe which uses the priveleges of the user that's logged on to the machine.
try to log on with the wimpy user and see if the problem occurs or just disable writing access on that directory for all users.

That's what I was thinking could be the problem.

>>just disable writing access on that directory for all users.

Been there, done that - file permissions got changed back to writable by some upstart process!

I believe that Internet Explorer uses the system account for stuff like you described.

If you want to test it out, go to a site that you know has a bunch of flash stuff on it, like http://www.shockwave.com
