Symantec Antivirus DWH****.tmp files

Hi,

For some reason, at around 1:00 a.m. symantec antivirus always opens and automatically starts to quarantine DWH****.tmp files. Every minute or so, it quarantines another DWH file. Here's a sample of the detection.

Scan type: Auto-Protect Scan
Event: Security Risk Found!
Risk: Trojan Horse
File: C:\Users\Jason Leung\AppData\Local\Temp\DWH762A.tmp
Location: Quarantine
Action taken: Quarantine succeeded : Access denied
Date found: February-10-10 1:53:59 AM

What is wrong? It appears to be a common problem but I can't find the fix (if any) for it. Please help.

Thanks,

K
