High CPU usage?

I wonder how much should be the CPU usage of notebook if you are not doing any task. I have insttaled many security appliances on my PC and now my notebookk is a bit sluggish. Just i saw mu cpu usage graphs and there are many spikes of 100% CPU usage. I want to know is this normal. I am using following real time security scanners, and other application

Norton internet security
Antihook
Winpatrol free
Prevx R1
Ms antispyware
ShadowUser trial
DU Traffic( a dial upmonitor)

I am just wondering if my CPU and memory usage is high. CPU graph is taken when notebook was idle with dial up internet connection working.

 

And this is Memory usage chart, taken with firefox open( 5 tabs) but no active browsing.

 

Hello,
It does look a bit ... strange.
Of all programs you have listed, I tried and ran all except Norton.
None of these caused such drastic spikes. Maybe you could disconnect from the internet and try disabling these one by one to see which one does the spikes?
Mrk

 

Most likely culprits according to CPU usage were

MS antispware -- 20 % CPU usage spike
Ewido guard ----- 09 %
ShadowUser ----- 02 %
Yahoo widgets --- 02 %
WinPatrol free ---- 02%
I will not mention exlorer.exe(3 %) as it is a system process.

This is graph after turning off MS antispyware.
( All data taken with dial up disconnected.)

 

And one more graph taken after turning off MSAS, Ewido guard, and ShadowUser.

 

you can click on the column name and it will put everything in order for you. so if you click the CPU column (sometimes you have to click twice for it to show at the top of the column) you will see the process go to the top of the column as it uses the CPU.

 

I have had MS antispyware installed five times and everytime I do I start getting the spikes right after the installation and when I deleted MSAS the spikes quit.
