A key logger
Aye, it's a called Perfect Keylogger Lite. Not a harmful program unless it's installed by a harmful person. In most cases it's installed by a parent to watch their kids. Or a spouse that's worried they're being cheated on. However, if someone that uses your PC wanted your CC number it could be used like that as well.

Thanks to avg, it found this key logger on my computer and removed the .dll file. I'm running w2k and this file was hidden in my c://winnt/system32/bpk

Not usually dangerous, unless installed by unknown, or dangerous person. For example i found bpk.exe after my friend visited (tried to get pass for my hotmail). This could be dangerous if someone used, lets say "sub7" and accessed the logs.

Simple application that sends no information out over the Internet. Used to record keystrokes. No screen shots taken and no application log recorded.
There's an enterprise version of windows washer on P2P that maliciously installs bpk.
Installed and ran virus check which found 6 infected files associated with the program ie : Trojan.peflog.A.....avoid like the plague

Yep, It's a keylogger, and that's that. No Adware/other Spyware is included. As with any keylogger, it can be used maliciously, but as far as I can tell it was not intended to be as such. It even allows you to display a disclaimer window when windows starts, letting users know that their keystrokes are being monitored...that's probably the only legal way it can be used on a shared/public computer.
caused major lag, cause the restart screen to pop up..very nasty..tried to send info to internet,,zone alarm blocked it..had a dat file ready to send. PC antivirus didnt find it
but what can I do when my computer has it , my deskstop is nothing
it appeared after install of Virtual Jenna, Norton tagged it as dangerous. Had to reboot in safe mode to get rid of it.
It does not send information over the internet, unless it is configured to.
this is official spy programm(sorry for my English) used for getting pass, screen display. often send information on e-mail

Best practices for resolving bpk issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active bpk process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the bpk.exe on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
