i have windows vista, and i have installed yesterday Bullguard antivirus.

I have did nothing but my cpu usage has been burst to 95%

i checked the log of task manager and found that svchost is taking too much cpu resources.

I looked on google to resolve the problem and got this site in search result.

I have did exact steps and my cpu usage has been reduced to 50%.

Still i think 50% cpu usage is too much ,i have installed only avast.

Dont know if it is the problem with bull guard or windows?

Any help would be so appreciated

There is may be a problem with that svchost, I think you system is checking for Windows updates in background and causes high cpu usage.

Hello and welcome to our forum.

Please know that, even if having multiple security solutions on your computer should mean that you are better protected, in fact these programs conflict, leading to computer instability and sometimes leaving you without protection.

Uninstall either Avast or BullGuard, according to your preference.

Furthermore, because you are using a Vista Computer and because the high usage is 50% not 100% and the affected process is SVCHOST, I strongly recommend you download and run System Update Readiness Tool for Windows Vista from Microsoft:

This tool will take a long time to run, but it's normal, so let it complete the job. After you run the tool and restart your computer, make sure you visit Windows Update, search and install all and any security updates. That should be the end of the problems.
