Hi all,

Recently my computer's starting switching windows by itself and I have no idea why. I've done a virus scan (AVG) and used Windows Defender to check for malware but nothing's turned up so far. I've also noticed that if I leave a Word document open it'll randomly type a symbol (the little box one) if left alone.

None of my keys are stuck or have anything underneath them.

How can I fix this?

It does sound like Malware. You could try an online scanner such as http://housecall.trendmicro.com/ in addition to the scans you've already ran. When did the problem start? How long have you been running on your current installation of Windows? Do you have Automatic Updating turned on? Any Warnings in your Action Center?

Trying that now. The problem started around 2 months back and I've been using Win7 since August. Automatic updates are turned on and there are no warnings in the action centre.

You could try a number of other free online scanners or what I would personally do is just reinstall the operating system, but if you've never done this before it could be a can of worms for you. Maybe someone else would like to chime in with any ideas..

What kind of sites do you visit? Do you ever open email attachments from unverified/unknown senders?

Never opened a dodgy email attachment and never visited a dodgy site I don't think.

Reinstalling the OS isn't a problem for me, I've done it many times before, but I'd like it not to come down to that if there's a simpler way.

Thank you, I will try those sites now.
