非常有效. 到以下website:

Download and install 後, let AVG do a complete scan. When it discovers the Trojan House Downloader Virus, it will delete it for you automatically.

This is a very good software. It will automatically update daily for new virus out there to protect the computer. Just schedule a daily complete scan, it will do the job.
