You have to go into safe mode to remove it from Windows XP Home
Believed to be part of the "Slipstream" internet accellerator package, so probably quite safe
  Stu Nutt  
Pop Up Blocker runs with Internet Explorer
  Daniel Snyder  
probably neutral but also possibly spyware
Was installed with "Slipstream" as part of accellerator package. Pop-Up Blocker from Oemtec, Ltd.,
dial up accelerator can be stopped in start up when not using dialup

Best practices for resolving pbhelper issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active pbhelper process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the pbhelper.dll 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.
