Are these virus? Can I delete them?

Question

Unknown file in Winstock LSP: C:/windows/system32/nlaapi.dll

Unknown file in Winstock LSP: C:/windows/system32/napinsp.dll

Unknown file in Winstock LSP: C:/program files/bonjour/mdnsnsp.dll

I have tried to google search them but I keep getting these sites I don't understand! I would just like to know if they are viruses/spyware/adaware or malware.

Answer 1

DO NOT DELETE THOSE FILES. they are microsoft files.



nlaapi.dll should not be disabled, required for essential applications to work properly

napinsp.dll is a system file created by Microsoft Corporation. napinsp.dll is part of Windows Operating System

Bonjour locates devices such as printers, as well as other computers.

they are not harmful.

Answer 2

They don't look familiar, however NEVER, EVER delete something that "Hijack This" finds if you don't know for sure what it is.

Hijack This is NOT an Anti Virus product, nor a spyware cleaner...  It ONLY reports certain settings in certain areas of the system.  Never construe any of these "findings" as being a virus.

If you remove the wrong LSP without restoring the correct system settings, you will loose all networking on your system.

Hijack This is not what I consider an "end user tool"  It is very powerful compared to most tools, but with that power, comes the need to know to use it.  Let's use an analogy of a safety razor (typical AV product) as compared to a straight razor...  The straight razor can accomplish much more than a safety razor, but it takes skill to use.  (I happen to use antique straight razors to shave with... and I know what kinds of cuts can be caused when learning how to handle one properly :)...  I just happen to love sharpening things... Playing with fire is also fun!)

Do a scan with Spybot S&D from http://www.safer-networking.org

It should find LSP anomalies and report them.  Sometimes it is unable to fix those problems, but it will pop-up a message with a link to a site that has a "fixer" tool for LSP problems.  Download that tool first, then you can remove LSP entries to your hearts content, and run the fixer tool to repair your network after the fact.  

Answer 3

If you are unsure of the security of your PC, then restart your PC in safe mode with networking
