Can anyone help please?

by Themisive / September 8, 2006 8:46 AM PDT

I have been getting files named Perflib_Perfdata_5b8 (the last 3 characters seem to vary) in C:\Windows\Temp for a while now. However, recently these types of files have also begun to appear in C:\My Documents\myname\Local Settings\Temp, the files are: Perflib_Perfdata_1b4 (and again the last three characters seem to change).

Thus in each of the two files, I could - and sometimes do - have as many as 6 or even more of these files. That they are associated with a programme is evident, but I don't know which programme is generating them.

Obviously I would like to stop them, or at least cut them down, I have checke the Event Viewer but can't seem to find anything so I wonder, has anyone else ever come across this problem.

I tried both links you gave me, in the second link there is a reply give an insight into what to do, apparantly you do:

Disable the Performance Logs and Alerts service.

smlogsvc.exe = Performance Logs and Alerts Service.


This is done it seems by opening msconfig and looking on the Services page. Some way down, there is a Disable the Performance Logs and Alerts service, what I did was uncheck it, then restart the computer.

Hopefully this has stopped the proliferation of these files, but I'll know better later. Incidentally they are caused by a something called Perflib_Perfdata.dat, and apparantly can be caused by a variety of things, one of which is the ATI Radeon Control Centre for the 9600 series video cards!

The ones infesting my C:\Documents and Settings\myname\Local settings\Temp have finally dissapeared -almost as if they have had their fling and gone home.

However, I'm a bit suspicious still, I read a post not too long ago with regard to rookits. Apparantly these seem to insinuate themselves onto the computer without your knowledge - and they can be very awkward to get off. However, I have 2 separate firewalls, a software firewall on the computer and a hardware firewall at the router.

Since I got the router, the erroneous Perflib_Perfdata files in C:\Documents and Settings\myname\Local settings\Temp have dissapeared.

i do intend to download a programme called RootkitRevealer, since this will apparantly attack the problem.

are anything to do with rootkit infections Themisive.

I've had those Perfib_Perfdata files myself and I believe they are just generated by the OS every thime the system is booted up. They should be deleted automatically at shutdown.

But I'm not saying don't bother about rootkits. It's always well to check.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
