Hi there,
I recently and foolishly clicked on a link posted on my Facebook page which opened Google start page when i clicked on the link. Since then, Windows Internet Explorer has been opening on it's own, even though Firefox is my default browser- occasionally asking me to download anti-virus software. I have backed up my registry, zipped and attached the attach.txt file as requested and below is the DDS.txt log. Any help would be massively welcome!!
Many thanks,
Holly.
