I have a problem, she cried.  :ranting:

The past couple weeks noticed my cpu spiking for no reason.
Cleaned, scrubbed...the whole 9 yards...no change except is gradually
worsening. Took everything off my desktop,,nope. running programs?.. nope
IE 7 kept crashing p.c. uninstalled it, will reinstall later.
Had conflicting Javas..uninstalled all instances...hopefully. Will reinstall later.

Nothing over 25%....yet. Started at around 4/7%

Explorer.EXE (capitals?) ->Wscript.exe (what in tarnation is network.vbs) and why does it run away when I try to open?

System   / lsass.exe

Services / svchost.exe (-k netsvcs )
              / svchost.exe ( k-rpcss )

I've searched all over and cannot find a correct solution. Many users are having the same issue.
(Blurry eyes and raging headache she has now)  :wacko:

Win XP Pro sp3
Dell Compaq 7100 P4
I use Avast-MalwareBytes-Mbar-Ccleaner-WiseCleaner regularly
I have tried Sys.Explorer-Rkill-SecurityTaskManger-SuperAntiSpyware-Frst
I have not done TDS-HiJack or Hitman Though I do have installed.
Have disabled darn near everything from start up ( Piriform )

Dell Compaq will not allow into safemode ( no f8 function ) and misconfig boot puts it in a continous start up loop.

( Starts pulling out her hair )  :smash:

I have read that I can try a modified boot.ini onto a cd,  

[boot loader]
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional"
/noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional Safe Mode"
/noexecute=optin /fastdetect

but real iffy about that.

Tried everything I feel safe with except the new software....

"How to chop your p.c. in half with one blow" :killcomp:

 I actually read the file details on one process that read .. I kid you not....."Destroy Window"

Now what the H E Double L Hockey Sticks ???

I've read article https://support.microsoft.com/en-us/kb/310353...seems a little drastic.

Seen here http://www.bleepingcomputer.com/forums/t/574445/annoying-cpu-usage-pattern/
The guy never came back I guess
Read a few others

Any ideas or instructions to help this damsel ( ahem ) in distress is greatly appreciatted.


P.S. It is late here here in FL, may not return till Mon morn.

Good morning :).


I see 2 things that I consider problems:


a.  IE 7...is outdated and poses a significant (IMO) security risk because of known vulnerabilities to malware.  IE is a basic part of Windows and you say that you "removed" IE, which I believe is impossible.  So, IMO, you have a system that is more vulnerable to malware than it has to be.  I suggest immediately installing IE 8, then visiting the Windows Update site for all applicable critical updates that are now not currently installed.


b.  You are using Wise software which I believe to be a "registry cleaner/optimizer".  BC does not support the use of such, see Registry Cleaner, Animal - http://www.bleepingcomputer.com/forums/t/526247/tune-up-utilities-2014-problem/?p=3303494 .  I would uninstall this application immediately (after addressing the IE issue above) and then follow up with running the chkdsk /r command, followed by running the sfc /scannow command.


To run chkdsk /r command:  Start/Run...type chkdsk /r (exactly as I typed it), hit Enter.  Type Y in new screen, hit Enter.  Reboot the system...the command will execute before booting into XP.  If you cannot boot into XP, you can run the chkdsk /r command from the XP Recovery Console.


To run sfc /scannow command:  Start/Run...type sfc /scannow, hit Enter.


Let us know how it goes.

Explorer.EXE (capitals?) ->Wscript.exe (what in tarnation is network.vbs) and why does it run away when I try to open?



Everything I have searched on this indicates a possible malware infection but a very old one. Is there anything in your startup folder? All Programs > Startup


The correct location for explorer.exe is C:\Windows\explorer.exe  Where is the location of Explorer.EXE? Where is the location of network.vbs?


The links are for reference only. Do not use any of the removal instructions.

@JohnC_21   Thank You.

I guess hamluis is stepping back......Thank You for your help Sir.


I have removed Wise-Had to remove SP3 in order to install IE8 ( that was a process )

Am not comfortable doing a chkdsk - I do not have cd, but I do have a dwlded cd of RD, just not sure of it.


As for locations JohnC


Can't post pic but    Start Up  -> Network

Explorer.EXE is at head of tree of Process Explorer ( system explorer )


Piriform cannot remove   C:\WINDOWS\system32\wbem\Logs

Cannot disable from startup either

GetUserDefaultLCID failed, restorting to system verion ( continuous loop )

I have original wmeb dwld.....will it overwrite if reinstalled?

Somehow all restore points are gone but latest 2.

All files were accessed 2/27-can't tell by what.

Had to dwld pics of camera today, I use a card opener via usb.  S & Gs I opened all available usb ports.

Found a Network.vbs program sitting between 2 DCIM folders ( Days pics were taken )

How could that possibly be on a camera card?



@severac....Thank You


I ran Mbam and Mbar and ESET. No alerts.   The only program that found this goofy Network.vbs thing was Wise Registry Cleaner and Ccleaner ( tools->startup )


I will run Mini ToolBox and all others and post results.   Many thanks to all with patience for me.

In XP do a search for Explorer.EXE. What is the full path of it's location? Also do the same for Network.vbs. I would also do a scan with Hitman Pro.


Bleeping Computer does not recommend the use of Registry Cleaners.
