Hi, I have a sony vaio laptop 'vgn-ns30es' and for the past week it has slowed down considerably. I'm not really sure what the problem could be but it is quite slow on when I'm on the internet or when I'm just using the laptop ie using Word etc. I have noticed some spikes on the CPU usage going to around 85% but can't seem to figure out whats wrong with it. I have scanned it with Mcafee and Malwarebytes Anti-Malware but this hasn't helped. Any help is much appreciated

1) McAfee is pretty useless in my opinion. If it were my system I'd uninstall it and replace it with any other av app.

2) Which process is hogging the cpu when it spikes?

im not really sure because there's nothing coming up that's causing the spikes. Its noticeable when i look at under performance when i load up the task manager. I can't seem to figure out what it could be. Is there anyway of improving the speed or getting it return to normal

Open Task Manager to the Processes tab, sort on the cpu column with highest usage at the top, see which process is spiking.

You said the cpu is spiking at 85%. Please post back with the process using the cpu when it spikes.

thats the bit I find strange. I can't seem to find anything that gets that high. Im using google chrome and and it goes to about 38% but that isn't too high. But if I'm just viewing performance it can spike to 85%. The rest of thhe processes do not go over 4%.

The percentage of cpu usage by the individual processes has to add up to what the cpu usage is. How does the system perform with a clean boot (msconfig - general tab - selective startup [uncheck everything] and reboot)?

If the problem persists with a clean boot, your system is probably infected. I suggest you post in the Am I Infected forum.
