New conficker Trick

Comodo is not detecting conficker files in a specific case. Conficker is setting itself to execute only permission and removing read from all users(even admin account) When I scan it is not found.

If I cacls VIRUSFILE /e /g users:R
attrib -r -a -s -h VIRUS file

and then scan it is found.

Anyway to add for comodo to reset the file permissions on those files so I dont have to fix by hand?

Can someone verify this command?

Could you upload the samle to the forum
