I already ran the spyware prgram spysweeper and the virus pragam , norton, and the only included with my ISP EZTRUST. nothing major was found, and no viruses. I finally decided to download a hijackthis log to see if anyone can help me interpret the results, and find what processes are causing my PC to run at 100% usage. Here is the log file, PLEASE HELP!!!!!!

This thread’s HijackThis output does not show obvious malware, which supports ’s point that the 100% CPU episodes are likely caused by legitimate background activity rather than an infection. Intermittent pegging is common when an auto‑update, scheduled task or background service needs CPU for a short time; the key is to capture what’s actually using the CPU while the condition is happening.

When the spike repeats, collect a short diagnostic snapshot to identify the offender. Use Task Manager (Ctrl+Shift+Esc), enable “Show processes from all users”, add the PID column and sort by CPU to note the top process and its PID. For deeper inspection, map services to processes or inspect threads with these tools/commands:

tasklist /svc > C:\svc-list.txt
msconfig
sfc /scannow

Process Explorer (Sysinternals) will reveal which service inside an svchost.exe is active and show per‑thread CPU and stacks if needed.

If a legitimate service or updater is the cause, let it finish or reschedule heavy scans/updates to off‑hours. To isolate troublesome startup items or services, perform a clean boot via msconfig: disable all non‑Microsoft services and startup items, reboot, then re-enable groups to find the culprit. Also check Task Scheduler for recurring jobs and Event Viewer for repeated errors that align with the CPU spikes. If high CPU persists even in Safe Mode or is accompanied by system instability, consider drivers, BIOS updates, or thermal/hardware checks (fan/heatsink).

For , these captures and the clean‑boot workflow will quickly pinpoint whether the spikes are benign background work or something that needs removal or configuration.

Hi jay2511,

Your HJT log doesn't show any indications that malicious programs are the cause of your problem.

Since you've already determined that something is spiking your CPU usage, I'm assuming that you've discovered that through Task Manager. You can sort your running processes in the Task Manager by their CPU usage just by clicking on that heading; what are the the most CPU-intensive processes listed there?

Thank you for the REPLY DMR..

And to answer the above question. It seems to be working okay right now.. its been two days that it was high at 100%, and my comp was very slow.. right now the most intensive CPU process is the most common one, System Idle process. at 87% -90%..

Once again thank you so much for looking at my log, and at least isolating the fact that I have no malicious programs..

If the "problem" reoccurs, you may just have some valid program or process running which needs to take priority over other processes every once in a while. Anti-virus programs and other programs with "auto-update" features can cause the sort of behaviour you're seeing.
