Intruder in my emails?

[habb]

W7, Mozilla, Google, free Avast.Domestic use, no dodgy website visits so far as I know.
About 2 weeks ago I was composing an email when a yellow strip came up saying something like 'someone else is tuning in, is it you?' and advising me to change my passwords, which I did.
I found in my Google history that recently the location, instead of the usual 'UK' had become 'Scampton UK' and this applies to my other email addresses. It came up intermittently but now it is there all the time.
I changed all my passwords to more secure ones but the word Scampton is sticking to me.
I live many miles from Scampton, Lincs.
Pc scans don't produce anything and the pc hasn't noticeably slowed down.
The pc recently went into PC World to be 'cleaned up' because the cursor developed a shimmy, and everything put back, but I can't remember whether this was before or after the email problem.
I would appreciate advice.
Thanks.

Oh dear Habb mate golden rule broken re emails never do what someone is asking you to do unless you know that person VERY well for instance your own family and if it was from your bank say for instance phone them and ask.

Having said those pearls of wisdom (been there done that) try running this - I know the PC shop has worked on it but worth try.
Download Kaspersky Rescue Disk 10 I know it says when the OS will not bot but this will scan everything from power up and will not involve Windows.

If you are not sure how to make the bootable disk itself see this it may take a few views to get the hang of it but it is really easy once you have done one
