Today Kaspersky Internet Security 2010 told me that I had a Malware called c:\Windows:nlspreferences on my computer and that I should fix it. I followed the instructions to Quarantine it and also to remove it several times to no avail. I had to reboot my computer each time but the malware was still there. I have seen some articles on Google that say that I should add it to the exclusions list. It this true or is there any way I can find and actually remove this malware. I am running Windows7 32bit and the last program I installed on my computer 2 days ago was Nitro PDF Professional Ver6. I did not get this message about the malware until this morning. Please help.

I know this thread is very old, but if someone would bump into it while researching on similar issues, i'll write my findings:


c:\Windows:nlspreferences is a ADS [stands for Alternate Data Streams. Read here more about ADS] file. And it is added - I don't know the reason why - by the Nalpeiron Software Licensing that Nitro [And a lot more software creators] are using for licensing and analytics with their product.


So it is definitely safe to add to the exclusions list. And the reason why Kaspersky wasn't able to quarantine it is because of it being and ADS file not a normal file.
