CPU loads are shooting up to 100 percent?

Trez_YTR · Dec 31, 2015

The only thing I'm doing on my Computer is running an anti virus scan at the same time just browsing the web (light browsing, no youtube or streaming). ANd then suddenly, my CPU loads shoot up to 90 to 100 %! Idk why that's so. Is this normal? Before whenever I'd run anti virus scans they don't get this crazy. I'm just worried something might be wrong with my PC.

What processes are showing high usage when this occurs? It's possible there is a task running in the background like Windows update which will increase your usage.

Look in task-manager, check the all users box and see what's running high cpu % processes.

Anti virus progams will run you up to 100% thats pretty normal

My antivirus doesn't do 100% CPU.
Are you getting 100% CPU or 100%HDD usage?

chrisb99 · Dec 31, 2015

It Depends on what anti virus it is

Please elaborate. I would like to learn (for personal enrichment) how and why you make this comment.

When i used Norton it always maxed out my cpu

chrisb99 :

Thank you. Then I think a fair question would be: What Antivirus is the OP using?

Karadjgne · Dec 31, 2015

I use Norton, doesn't put either my 3570k or my 3770k anywhere near 100% usage, whether it's background process or active.

Hmm it did it to my i7 3770 when i had that computer Thats a while ago so they could have changed that tho

Yeah, Norton was in a little trouble. Even as good as their intentions were, that program gets its nose into everything, its a deep diver kinda thing, and with all the checks and balances going on it was slowing pc's down in performance, which was giving it a very bad reputation with many ppl as they didn't have the best performing pc's to begin with, so couldn't afford the loss. Norton is still a deep diver, but there's been a lot of work done to minimize it's obtrusiveness while still retaining it's ability to catch issues. Free Antivirus is very popular, but is mainly manual, it'll only catch bugs ready on the system, you have to pay for the pro versions to get the live time security. I luck out since my cable Internet gives me Norton for free, combined with malwarebytes I'm pretty well covered. But even running both simultaneously, still won't put cpu to 100%. Only thing so far that has, other than stress tests was a font issue developed by a failed nvidia driver update, but that was easily fixed. Whatever is popping op's system will be in the processes tab in task-manager, all users. It's just a matter of duplicating the issue. Many times its actually malware doing a burst broadcast to its cookie sites, of which there can be thousands, so will eat cpu% easily.
