Trend Micro OfficeScan 10 offers us some compelling features, so we're upgrading from Trend 7 (stop laughing in the back there, we like old software!). We've found 2 significant gotchas:
Disk filler
We install the Trend server software (i.e. the part that farms out the new virus definitions to the clients on that network) in the default location - C:\Program Files\Trend Micro\ on our local file/print server and soon enough, it fills the entire C: progressively killing off services, until file and print services die, and the users start calling me. The culprit: C:\Program Files\Trend Micro\OfficeScan\PCCSRV\Apache2\logs\error.log has grown to 3 GB (yep, 3 gigabytes of error logs!). I'd love to tell you what was in that file, but Notepad won't open a file that big, and Wordpad wants to make a copy of it - on C:\temp I guess - before it opens it, making the problem even worse. So I just killed it, shrugged and moved on.
Weird Word Wackiness
OK, this is clearly a corner case, but it happened to three machines on one network. Trend 10 on the clients (two of them w2k, one XP), they try to open a Word document from a Samba file share, and...can't do it. With OpenOffice instead of Word, it works. With the documents in question copied to a Windows 2003 file server, it works. With Trend reverted to V7, it works. So: Trend 10 + MS Word 2003 + Samba file server = bizarre errors.
