Two mice installed??

Dell / Dimension 9150

Specs: Windows XP, 3.0Ghz/1G
When I power up and enter Windows, according to my hardware device listing, I have two mice installed. The first one is clearly related to the hardware and if deleted stops te mouse from working. The second one if deleted makes no difference. I noticed this after I had my hotmail account raided a few months ago and feel concerned that this may be connected to some form of malware or even allow someone to access my computer remotely. Is this normal?

If Windows installed a generic Mouse driver and then you installed hardware specific drivers it can show two devices. You can highlight the non working one and disable it.

I doubt it has anything to do with any malware. Post the names of the two listings.

I actually delete the second mouse, however after a reboot or start up it reappears. I have only ever used the mouse that came with the computer and I know for a fact that the device manager only ever listed one mouse originally. I have had the puter for two years and the 2nd mouse appeared in the last few months This is a PS/2 2 button with scroll wheel. The device manager lists it as "HID-compliant mouse".

You may have received an auto update to WinXP that is now causing the second entry. I have seen that situation before.

As I said, if you disable it in that profile it won't keep re-installing.

Look at the driver files for both the listings. The HID one will probably have HID-compliant mouse - 5.1.2600.0 for the drivers. The other listing may have a different driver installed.

Are you using a PS/2 to USB adapter on the mouse?

Yes, it is PS/2 to USB. Thx, I will disable rather delete next time I start up. Funnily enough as I was advised to install Service Pack 3, I did so using the Windows update last weekend. I haven't used update for over a year until then.

When you installed SP3 auto update was enabled by default.

Why are you using a PS/2 to USB adapter? Connect directly to the PS/2 port. Better anyway and frees up USB resources. The second mouse entry will probably go away too.

Sorry, misread your earlier comment. It is a straight USB connection (no adapter).

If you are using a USB Mouse you should see both entry's, PS/2 is native to the OS

Delete BOTH Mouse entry's and reboot, Only the connected Mouse should appear in Device Manager. That is unless you have a program installed that loads the USB (HID Compliant) Mouse Driver.

I'd say, "much ado about nothing".

Check all of Device Manager for problems.

There is nothing to learn from someone who already agrees with you.
