Hello,
I'm hoping someone could give me some help and guidance on this. I use Kubuntu 18.04 and Firefox 73.0.1 (64-bit). I was looking for web sites dealing in mattresses and in the search results was a site <snip>. After clicking on the link, there was a slight delay and then a page appeared with animated confetti saying I'm Firefox's 5 billionth search and I've won a prize. Thought it was a scam straight away and closed Firefox and restarted it. Have used various flavours of Ubuntu for a few years now and never had anything like this before. Did searches on net for info on the scam and it seems to be spread by adware. I checked add-ons in Firefox and I only had 'OpenH264 Video Codec' and 'Widevine Content Decryption Module'. As far as I can remember, I haven't installed any extra programs that didn't come from Kubuntu's software centre and these are only VLC player, LibreOffice, Chromium (only have this for testing in case have problem seeing a page in Firefox), Thunderbird mail, Cantata, K3b, ClamTK. In Firefox, I've gone to Help->Troubleshooting information->refresh Firefox which put everything back to default settings. I have since reset back to recommended settings described in https://wiki.ubuntu.com/BasicSecurity and now have just 'OpenH264 Video Codec' as the only plug-in (as it's automatically installed by Firefox). Is there anything more I can do to safeguard myself?
Regards
Rob
