We get scared on downloading

We get scared on downloading any software from internet, especially on the corporate network. Thogh Sandeep's name tag suggest he is a Trusted Advisor. However my point is not refering to his suggestion. I need a best practice in general.

Can someone suggest, how?

Once you have Enable Debugging for Netlogon Service you will be able to see which clients are attacking.
Once the source is found it can be remidiated and cleaned.

By disabling Scheduled Task Service
We can stop Downadup from spreading .As it created Schduled Jobs and spread across the network.

Disable autoplay
That is the most important for every worm

I used GPO to disable

I used GPO to disable autoplay and used SEP to block access to any autoplay.inf file. Nothing at all can possibly start automatically around here. of course most important is the MS patches!

@ShadowsPapa: Definitely

@ShadowsPapa: Definitely agree with you on that.
By the way is there a method to disable USB devices and not disabling USB KB and mouse?
Made a test environment and USB was successfully blocked on the specific client.
the problem is the mouse was also disabled.
thanks.
