Frequent 3048,3 Errors

I have NIS 2013 on Windows 7 x64.

 

Twice or three times a month I receive the 3048,3 error.

 

Yes, I have read the knowledgebase article.

 

No, my computer is not infected (according to NIS and NPE; also according to Malwarebytes.)

 

It's not the end of the world. I just wish it wouldn't happen.

 

Any way to stop this error from recurring?
