For the last month or two I've had a pop up advising that my computer is infected with a virus and telling me to download software to remove it. The website is   < secureservice.usquicksysutils.xyz > which I copied earlier - not sure if the previous instances were the same website but they were very similar.  This only happens on Ebay. I have wasted some time trying to report this to ebay but they are very much incognito. There is a link on one of their pages to a police fraud site which for whatever reason is incorrect or outdated. 

Very poor performance from Ebay in that there is no effective means of reporting this and the fact that the problem has been in evidence for some time and they can't be bothered to fix it. I don't want to have to run a virus scan every time I visit Ebay so may not be visiting much in the future.
