This is what my desktop shows:

I have Avast and you can see it has added aswKbd to the UpperFilter.  Apparently Avira does not use the UpperFilter.  I also just have the one Keyboard instance.  Not sure why you have three.

Since it's working for now I guess we just have to wait and see if it goes bad again.  I will try and figure out why you have three keyboards.  Will fire up my laptop and see if it has multiples too.

Hi. Thank you for all your help. If you figure it out, let me know. It's all Greek to me. So far today, typing is issue-free. (Tempting providence?)

Hello there. Sadly, the problem of random beeps and key strikes not producing type has returned. What's new/different is the increased frequency of beeps (happens a lot ias I use the trackpad to move the cursor, though not every time). Would value your help, as ever. Thank you very much (that took forever to type due to the issue).

Let's rerun the last fixlist to look at the Keyboard registry entry and see if anything has changed.

 

Attached File  fixlist.txt   242bytes   4 downloads

 

Just post the fixlog.  No need to rerun FRST scan yet.

 

When I look at my laptop I only have the one keyboard instance and it has three upper filters.  It has one for the touchpad, the usual keyboard one and then one for Avast.

Thank you. Typing this morning - at present - okay after start-up. I remembered there was a problem last time I tried to use the fixlist thing so went back to page 11. Back then, you'd said download the fixlist and move it to desktop. The first time I did this just now, it disappeared entirely after the drag & drop! I also  noted some latency in trying to shift the window to one side so I could drag and drop (could it be a touchpad issue?) So I tried again but the fixlist had also disappeared from the list of downloads so I downloaded it again and then it re-appeared together with the second attempt's one with a very long file name. I dragged and dropped the first one into the desktop and then it said there was no fixlist (see screenshot) but there was so I'm guessing it's not in the desktop at all, although it was last time. Yours very confused. Any idea what I'm doing wrong? Thank you.

It is there, the fixlist, sitting on the desktop, but the same message appears.  Thank you.

It's not named fixlist.txt.  Instead it is named fixlist(1).txt.  Right click on it and Rename and make it say fixlist without the(1)

That didn't change from before.  I wonder if the lack of a touchpad driver in the line:

 

UpperFilters    REG_MULTI_SZ    kbdclass

 

Is part of the problem.

 

Search for

device manager

hit Enter

 

Click on the arrow in front of "Mice and other pointing devices"

Right click on your touchpad and Uninstall Device.  Reboot.

 

If that doesn't help then look on your PC makers website and see if there is a newer (or even older) touchpad driver from what you have and try to download and install it.

 

I can look for one:

 

Right click on the touchpad entry under Mice and other pointing devices and select properties then click on the Details tab.  
Change Property to Hardware IDs.  Click on the top one then right click and copy.  Paste that into a reply

Thanks. As the screenshot shows, there's nothing there in the way of Touchpad.

 

(Okay, so I tried to upload the screenshot three times - in vain). Essentially, when I click the arrow to the left of Mice and other pointing devices, the only thing that displays is HID-compliant mouse. That's it.
