Problem on Upgrading Trend Micro OfficeScan

After upgrading our current Trend Micro OfficeScan 7.3 to the newer version 10.0 release, the problem started there.Computers with client OfficeScan installed has these symptoms:

1. CPU utilization increases to 100%

2. When using Network monitoring tools as such as Ethereal, you can see error on TCP packets like this "STATUS_NO_SUCH_FILE"

3. When try to unplug its LAN cable CPU utilization decreases like crazy.

So what's the solution dude?

ok, best solution is to get hotfix from trend micro if possible. This is what i am talking about.Here is the steps:

1. Go to your master server or TM server master console.You can connect thru your browser usually "https://servername:4343/officescan/console/...." and login your admin account

2. Go to this link >> networked computers, global client settings

3. Uncheck "Show the alert icon on the windows taskbar if the virus pattern file is not updated after x days" shown image below.

4. Go back to you server which was just upgraded version with Officescan client and update it as shown below to replicate the new settings done from TM server.

Then, thats it.I know that doesnt make sense but it worked for me.

Actually that features once enabled, the clients searches for an update continually to your TM server.Sounds eating all you bandwidth making your network congested.This is a big problem especially on file servers domain controllers where there are a lot TCP accesses.You can see srv.sys used more CPU resources when you use process explorer tool.
