Laptop freezes during antivirus scan

by thequeenofcurdsandcream / November 28, 2009 9:37 PM PST

Recently my laptop has frozen and refused to complete an entire antivirus scan. I was using McAfee, but was advised to uninstall it and install Antivir instead, but this didn't solve the problem. I then had a new motherboard fitted, but this didn't solve the problem, so finally had the hard drive reformatted. However I'm still getting the same problem, although not as badly. The scan can't seem to proceed beyond a certain point, although it doesn't make all my other programmes go non-responsive anymore, and the computer clock doesn't stop at the time when the scan froze.

I'm running a Dell Inspiron 1525 Intel(R) Core(TM)2 Duo CPU T5750, with Vista SP2 and my browser is Firefox, although I've had the same problem running the scan with IE.

There are deep issues here.

You have a choice of spending the time to be a computer repair person or try simple work arounds. I suggest you:

1. Put it on a laptop cooling pad.
2. Use the CPU speed controls to tell it to run at a lower clock rate.
This upsets some but I have a 6 year old laptop that runs fine once I did that. Cheaper than repair or replacement.
3. Do the scan in safe mode.

This will not fix issues, will not get around bad hard drives, corrupt hard drives, bad sectors or other bad hardware.

4. Unplug all USB devices, disconnect networks shares and printers.

There are options short of replacing the machine.

I am about to order a Belkin laptop cooling pad as these seem to have the best reviews. How do I alter the CPU speed?

Why order that?

You can test if that will help in advance by tilting up the back of the machine to give it more air.

I have exactly the same problem with my Acer Aspire 5720.

I have tried to identify the problem. It freezes up the moment it gets to a certain file in the Cyberlink/Shared Files folder. The file name is L fpng13n.dll. I have tried a Windows Defender scan with the exact same results. I tried to uninstall the Cyberlink program, but It doesn't have an Uninstall application. The other problem is that the moment you click on the particular file, the laptop freezes up as well. This happens whether you right-click or left-click.

It is also not possible to uninstall it from the "Uninstall Programs" in control panel.

So why not?

Tell the scan software not to traverse or scan that directory? All scanners I know of have exceptions or places to tell it not to look in that directory. Makes you wonder why such a feature is there.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
