Hi Broni, many thanks for your offer of help.
I have done the Malwarebytes scan and it didn't detect anything (although it did yesterday and I removed the threat) the log is as follows:

I clicked both the links to download the GMER program but each time Firefox said the following:
Unable to connect
Firefox can't establish a connection to the server at www2.gmer.net.
The site could be temporarily unavailable or too busy. Try again in a few
moments.
If you are unable to load any pages, check your computer's network
connection.
If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.
Shall I wait for your instructions before I download the DDS program?
