Usually I use Process Explorer when I am troubleshooting malfunctioning programs. You get running processes' hierarchical display that shows detailed information on how certain applications work.

Even the ones that don't improve the CPU usage situation are teaching me a lot about my puter.Process Explorer basically does the same as the Windows Task-Manager, although it is much more powerful. Thanks everyone for all your suggestions.
When I shut that down, explorer.exe CPU usage dropped from 9% to 2%. I can try switching back to Zone Alarm if you think that would help, but I don't think that decision is related to the CPU usage problem.ĭid you see my previous note where after selectively shutting down all services, the only one that made a significant difference was Network Connections. I used Zone Alarm for a few weeks and found it intrusive. I am currently using the Windows firewall. All the other other computers in the house are wireless, this one is not. I am hard wired from the ISP modem to the wireless router to this computer. It is hard wired from a port on the wireless router to an ethernet port on the desktop.
This computer is a desktop, and is set up right next to my wireless router. It is still showing explorer.exe at 8% and taskmgr.exe at 3%.
I disabled the Applications Layer Gateway service, rebooted, and there is no noticable effect on CPU usage. The only reason I mentioned IE in my post was because I provided a log from TCPView which would have shown an entry if IE was running, so I told you it was not. I understand that explorer.exe (which is the process using high CPU) is windows explorer which manages desktop functions, as opposed to IE or Iexplorer.exe which is the internet browser. When I checked, I was already set to Ultra DMZ Mode 2. I hadn't read that article, but I had seen another that explained basically the same process. Thanks for taking the time to try to help. In the meantime, if you guys, or anyone else, have and other thoughts or ideas, fire them my way. That may take a couple of days, so I will get back to you on the results. However, armed with the knowledge that CPU usage is normal in safe mode, and the fact that non-MS services seem to not be the problem, I like your idea of alternating which MS services I shut down between reboots to see if I can find the culprit.

I tried it again tonight and the CPU usage with all non-Microsoft services turned off is the same as in full normal mode. I already had tried shutting off all but Windows services, and it did not improve CPU usage. I pretty much have already covered all the points in that article you had me read. Having this information is like having a date with a beautiful woman you know its a good thing to have, but now that you have it you don't know what to do with it. After filtering out information type messages, I have 212 system errors, and 42 application errors. I ran the program you gave me for looking a event logs. I'm not saying it can't possibly be malware, but if it is, it is hidden too well.Ģ. After numerous scans of all types, and evaluation of my HJT logs, I was given a clean bill of health by the tech experts in that forum. I ran a thread in the malware forum for about 10 days before I started a thread here. American Megatrends BIOS, version 07.00T, released 04/02/01Īny and all help / advice is appreciated.ġ. Windows XP5.1 (build 2600) Service Pack 2 I have disabled most of the unnecessary services, uninstalled all applications I don't use, deleted all unnecessary files, reinstalled the latest SP2, and updated most of my drivers. What is this process that explorer.exe keeps opening? When I run Process Monitor, the following 9 lines keep repeating continuously:ħ378 1:07:15.3898193 AM Explorer.EXE 1340 RegQueryValue HKLM\System\CurrentControlSet\Services\Tcpip\Linkage\Bind SUCCESS Type: REG_MULTI_SZ, Length: 132, Data: \Device\ SUCCESS When I use Sysinternal's Process Explorer to see what processes are running beneath explorer and taskmgr, I get the following: opening any application (in normal mode) immediately spikes CPU usage up to 100% for several minutes CPU usage in Safe Mode is normal, 1% for taskmgr.exe, 99% System Idle This did not resolve the high CPU usage problem, so it was suggested I start a new thread here.
I had a thread open in the Security and the Web forum for the past ten days, and with the help of the resident experts there we cleaned any and all nasties off my system. When the system is idle, with no applications other than Task Manager running, CPU usage is 15%, with explorer.exe at 11% and taskmgr.exe at 4%. My computer has slowed right down, and task manager shows abnormally high CPU usage.
