From time to time, antivirus software sometimes reports files in the Second Life cache directories as viruses.

These are almost certainly false positives. There are two major problems with trying to upload a virus into Second Life, let's say as a texture that subsequently downloads into someone's unsuspecting cache and there executes its maleficent purpose:

So basically, if someone tried to upload a virus into Second Life, chances are good it would never make it in there in the first place, and even if it did show up in someone's cache, it would just sit there and be useless.

You can safely turn off virus scanning in the following directories:
 
* The Second Life skins directory (i.e. C:\Program Files\SecondLife\skins )
* The Second Life cache, which you can find in the '''Network''' tab of the Preferences window in Second Life under '''Disk Cache Location''' (i.e. C:\Documents and Settings\User\Application Data\SecondLife\cache)

If you are experiencing slow performance in Second Life, the problem may be your antivirus software. We've found that on some systems, Norton AntiVirus can significantly slow down the texture cache system introduced in 1.14.0.

Antivirus software also occasionally misidentifies files in the Second Life cache directories as viruses. Don't be alarmed if you get a virus alert about Second Life. These are almost certainly false positives, and in any case Second Life never actually executes code in the cache, so there is no danger.

To prevent false cache virus alerts and improve texture cache performance, turn off virus scanning for the following directories and add them to the list of ignored (that is, trusted) directories for Norton AntiVirus:

  • The Second Life skins directory (C:\Program Files\SecondLife\skins )
  • The Second Life cache, which you can find in the Network tab of the Preferences window in Second Life under Disk Cache Location (C:\Documents and Settings\User\Application Data\SecondLife\cache)
