The following provides some information about viruses and what steps you can take to prevent them.
What are viruses?
Viruses are computer programs that are designed to damage files or systems. Viruses generally are designed to spread to other files and/or computers. By attaching to e-mail or disguising as e-mail from your computer, a virus can travel quickly and silently to thousands of users without virus protection.
Will the NetEase AntiVirus protection catch all viruses?
No. There are several reasons a virus may not be caught by our AntiVirus Gateway.

It may be a new virus that has not been added to our virus definitions.
NetEase checks for updates hourly. When new definitions are released our server is updated within the hour.
A virus may spread through another method other than e-mail.
Trojans such as w32.Blaster.Worm were spread via TCP ports across the Internet. Other known malicious programs are spread through chat programs, file share programs, etc.

Security Tips

How will users know if a virus has been blocked?

Initially, NetEase was sending notifications that a virus has been blocked from entering your Inbox. The intent of the notifications was only to keep you informed however many customers complained that this was confusing to them so we stopped sending the notices.

Will NetEase inform the sender concerning a virus that was blocked?

We will not send automatic notifications to senders when a virus is blocked. Many trojans use random addresses that are not the address of the person who has the virus. Many times these random addresses are retrieved from the users address book or mailbox. In order to reduce false alarms we do not send notifications to those addresses.

I received a notice saying I had a virus. What should I do?

NetEase does not send automatic notices to virus senders due to the reasons stated above. However, if we detect your connection attempting to send out viruses through our mail gateways we will send a Trojan Warning that generally will contain instructions on how to resolve the problem. Since many malicious programs forge the e-mail address it is common to receive notifications from other mail servers saying you have sent them a virus. If you are confident that your computer is virus free you can safely ignore automatically generated notices.

NetEase sent me a trojan warning but I do not think I have a problem.

NetEase will not send you a notice unless we have proof that your connection has been transmitting a virus or trojan. In the event that no action is taken on these notices then it is possible that Internet access will be suspended until the issue is resolved.

What additional steps should be taken to protect my PC

Check the Security Tips page for ways to secure your computer while connected. Critical items to check include operating system updates and virus software with updated definitions. With several new virus being introduced daily this is a task that should be performed frequently.
