Computer Problems!?

Question

I downloaded Microsoft Update for my computer, but now it has slowed down loads and keeps crashing! 99% of the cpu usage is going to a thing called scvhost.exe, does anyone know what this is, or what i can do to fix the computer, i tried restoring pc, but is still slow, and cpu is working hard on system idle process!

Answer 1

I have had this exact problem on PC. Windows update caused the process SVCHOST to run at 100%

I just let the update process complete. I left the PC on overnight and by the time I woke up the update had finished and the processor usage was back to normal. I guess it took hours to complete but it sorted it self eventually. This is worth a try before reformatting etc etc

Note:- This happened on a clean install, just after I had reinstalled XP. To this day I dont know what caused the problem...twas very strange

Answer 2

If you believe that this new update is the cause of your problems then you may have either a virus or a problem with the update.
Try running an anti-virus and if that doesnt turn anything up then reinstall the OS or remove the update via "add remove programs". Also, check to see if this is a hardware problem, maybe your CPU has burnt out or it will if it is constantly a 99%

Answer 3

SCVHOST.EXE RECOMMENDATION
Description: scvhost.exe is a process which is registered as W32/Agobot-S virus. This Trojan allows attackers to access your computer from remote locations, stealing passwords, Internet banking and personal data. This process is a security risk and should be removed from your system. Scan Your PC including scvhost.exe to Detect any Security Threat Recommendation:

Ew, you got some major issues. SVCHOST is the processes that are split up between your services on your computer. They are not supposed to be taking more then 5% of your cpu load at heavy usage..

Do nothing at this time with the results! Not all results will be malware! Google each result.

Answer 7

If it is svchost this is a necessary windows component, if it is scvhost as you put then it may be something malicious (or just a spelling mistake on your part). do a full antivirus scan and adware scan to check for anything malicious.

to ensure that windows components are intact go to start run and run sfc /scannow this will check windows components are fine, you may need to insert your windows install CD to do this.

Answer 8

Then get rid of Microsoft Update. I would also recommend getting more RAM and upgrading your processor to a faster and better one.

Good luck!

Answer 9

Go to the Control Panel Add/Remove programs and remove the update. Before you reload it get someone who knows more to see if your computer can handle it.

Answer 10
