» The process Ancillary Function Driver for WinSock or AFD.sys belongs to Windows. afd.sys is located in the folder C:\Windows\System32\drivers. Known file sizes on Windows XP are 138,496 bytes (88% of all occurrence), 131,968 bytes, 138,368 bytes, 130,688 bytes, 138,112 bytes, 273,920 bytes. The driver can be started or stopped from Services in the Control Panel or by other programs. afd.sys is a Windows core system file. The program has no visible window. File afd.sys is a trustworthy file from Microsoft. afd.sys seems to be a compressed file. Therefore the technical security rating is 0% dangerous.

Afd.sys virus is a rootkit infection that uses the same name as a Windows core system file toescape the antivirus protection. Afd.sys may destroy your internet access if you don't completely get rid of it. So, the typical symptom when you are unfortunately infected with this nasty rootkit infection is that you may be kicked out from the internet. Afd.sys virus is created to help computer hackers to remotely monitor the compromised computers and assist other malicious computer items such as VirTool:Win32/Obfuscator.AET to install into the infected systems without any consent. You are recommended to remove the afd.sys virus immediately once it is found. This is a very nasty rootkit which, unless you are very expert with computers, is very difficult to remove.

  2. RICHARD SKALA replied on February 16, 2013: » There is no such thing on my PC as tbbMeter. When BSOD appears it says it is to do with afd.sys and not pssdklbf.sys. Apparently afd.sys is to do with the network and it all started when i reinstalled my driver. The driver is up to date.

  3. DONALD SELL replied on February 17, 2013: » The bluescreen was caused by the pssdklbf.sys driver. This driver has something to do with packet sniffing software. Update or remove the pssdklbf.sys driver and its associated software.

  4. RICHARD SKALA replied on February 18, 2013: » If i were to use device manager to update the driver, well, how would I? I dont have the device name. If this is not possible, how colud i update the driver?

  5. ANALYNN NEWSOME replied on February 20, 2013: » It does not need to have a device associated because its a .sys file. I have found this information, the file is from this company: and could be part of this product: . ( this is pure speculation)

    However it might give you some indication of which product you should de-install to get rid of the driver. If the above does'nt help, there might be a possibility to stop the driver from loading by some registry editing.
