Environment

Issue



Virus definitions consume a large amount of disk space.

Symptoms
The virus definition folder that is located in C:\Program Files\Common Files\Symantec Shared\VirusDefs fills with temporary folders. The temporary folders are called tmpXXXX.tmp, where XXXX are hexadecimal characters. The temporary folders take up large amounts of disk space.

 


Cause



Virus definitions may be corrupted.


Solution



Note: To check if the virus definitions are corrupted, download and run a "scan for common issues" with SymHelp. 

WARNING: Do not clear the VirusDefs folder if LiveUpdate Administrator (LUA) 2.1 is installed. This will cause LUA to report that engine updates are corrupt until the next set of engine updates is released.

      1. Go to Start > Run
