VAC is proprietary Valve software primarily used in games developed by Valve (HL2, TF2, L4D)
 
Have you tried going to PB's site and getting their updater?

Go there and download "PBSETUP" and run that. I haven't ran it in a while but If I remember correctly it should detect the games youve got installed and update the PB client for those games.
 
Hope that helps.

I never get kicked.  Some are lucky and some are not.

I dunno. I've never had problems with PB that I couldn't solve and in most cases IIRC, this updater was the cure.

Give it a shot, It will probably solve your frustrations. Then you'll forget all about it Hopefully, it works.

 
yea hopefully unless i get this when trying to download the updater

Try that page. I just DL'd it and didn't have any issues.

I'm with you...Not a fan of PB but I'm not sure what you mean by no cheaters with Black Ops and VAC.  There are hacks all over the place.  Just days ago I was on and a player was using a powerful LMG and wall hack.  Had like 59/3 kill death ratio.   

PB gives me a ton of hard drive lag.. but not after i got an ssd!

I get kicked by Punkbuster in BFBC2 for the same thing. If they're going to force us to use something then they should at least make it work correctly.

The number one cause of this issue, is failing to launch the .EXE correctly.

  PB service go over 0-1% CPU use... 
      

 
how do you launch the exe incorrectly? or correctly..I just use my desktop shortcut.
been watching pb services as of late and find it to be using about 13% of the cpu.

Try reading this ....
Some other software programs such as virus scanners, firewalls and Internet security software packages are suspicious of any new services and kernel drivers when they are first released. Some of these will block our new components thereby causing the "Losing Key Packets" kicking. Until these various packages are updated to correctly identify PnkBstrA.exe, PnkBstrB.exe, and PnkBstrK.sys as components of the PunkBuster Anti-Cheat System, players who experience PunkBuster kicks due to these conflicts need to either manually adjust the settings of the other software running on their system or disable the other software while playing on PunkBuster enabled servers. The new PunkBuster components make use of network resources and also frequently update files in the Windows system folders. This activity triggers warnings or blocks by some other security programs, some of which consider all unknown programs as threats or malware. Our new components are simply extensions of the existing PunkBuster system using new services and kernel software drivers, and are each signed with Verisign / Authenticode digital signatures for verifiable authenticity purposes. Most major security packages do not block our new components; users with other software that causes these conflicts should contact the vendor of their security package and request an update to correct this conflict.

thanks for the in depth instruction but all ya really needed to say was launch from the start menu..lol, but  I tried what you said there and found that at first it did not use any cpu cycles. but then it did come back up to 13% or so. my issue my or may not be pb  I am not getting kicked by pb just a hard system lock up with screaming audio. not really relating to this topic.
