Recently I’ve been seeing more people having problems with Norton Anti-Virus giving false positives on various viewers used with Second Life and OpenSim. The problem us usually the file slplugin.exe. The SL & OS viewers run multiple copies of file. So, a false positive renders the viewer unusable.
Today I saw this article: Symantec Software Update Rendered Many PCs Useless. It basically says if you have Windows XP and update your Norton Anti-Virus, it will eat your computer. Poof! You are down with no way to find out how to fix the problem.
Warn your friends that run Windows XP.
If you are a Norton AV user, consider moving to another AV program. Microsoft makes a free anti-virus program for Windows that is pretty good. It called Microsoft Security Essentials. It uses far fewer resources then Norton. So, you should see your computer speed up.
Neither Norton’s nor Microsoft’s AV appear in several AV Top Ten reviews of retail AV packages. I think that is a clue that AV makers are paying to be in those reviews. Generally Microsoft makes it into the top 10.
I prefer ESET for Anti-Virus, but that an opinion. I have not done personal tests for some time. But, I have found there email support good and reasonable fast, 1 business day.
Avast Free Anti-Virus is very popular. It is the top download on Cnet. It gets good, not great, reviews on performance and security.
