Specs: Windows 7
hello
a workmate has a relatively new laptop, bought late last year. since yesterday his computer has been responding really slowly. applications take a long while to open and close, even a forced closing with the task manager takes a while to effect.
the specifications of the laptop are as follows:
-model: Dell XPS L502X
-windows 7 home premium SP 1, 64 bit
-processor: intel (R) Core (TM) i5-2410M CPU @ 2.30GHz
-4GB Ram
-hard disk: 404GB free of 576GB

There arent any recent istallations made on the computer. when running just 1 application the CPU usage fluctuates between 3 and 11%, physical memory usage between 38 and 43% (about 1.50GB), and 102 processes are running.
is there anything that seems out of order here? the only weird thing that happens is his McAfee antivirus keeps popping up a message that real time scanning has been turned off.

thank you all, we terminated a bunch of programs that start automatically when the computer starts up and that seems to have done it, that was two days ago and he hasnt complained again.

thanks

What application is it, my intel I3 2310M goes from 2-8% with over 20 tabs in opera with something loaded in them, you might have a virus, keep in mind your cpu is an i5, the application your using might be slow and buggy.

Also viruses can sneak into his computer and bypass the antivirus so keep that in mind aswell, what processes are running?

Down load Malwarebytes anti-malware to scan for malware slowing down his computer.

Many users around here (including myself) don't like the McAfee antivirus. I would recommend getting rid of it and getting another free antivirus (like Avira or Microsoft Security Essentials).

As jar_nar2012 said, a virus could be on the computer. Use the software jay_nar2012 linked to.

Also, 102 processes is a little much I think for Windows 7. The average number is around 70 on my computers.

I just checked how many processes i,ve got, have 101, including itunes, windows explorer and opera with a dozen tabs, and my CPU usage ranges from 0%-15% most of the time, less with itunes and WE closed, mine not slow, i could open a ton of calculator windows and it might slow down a little, my current RAM usage is 63% ( 64-bit win7).

Your friend's antivirus could also be slowing down his laptop.

@jay_nar2012: I've never seen a computer with Windows 7 using 100+ processes, but I guess they are out there :). What I meant was with the computer at idle though. The Windows 7 computers I have at idle are around 70 processes.

An easy start is to try a restore point. If that fails then use performance monitor to see various (almost thousands) of metrics to be measured.

No matter what company's security software you have, all can miss some issue. Rootkits and other malware can get past them all.

Be sure to run memory diagnostics to see if both the memory passes and that the correct amount is being shown and used. If one stick stopped working the system would slow down maybe.

Hang up and live.
