Thanks for your comments. I've done a complete system scan with no problems found. Cleared the cache on all browsers. Still get the f_xxx files being removed, very annoying. Also get "Web Attach JSCoinminer Download 6" & "Download 8" notification of stopped & removed by my anti virus when I connect to Shipspotting, no other sites.
Iím getting a lot of cache files being blocked by my anti-virus, is this the same problem? Files are all various f_XXXXXX numbers e.g. F_011356 Problem only on shipspotting.com on different browsers, all other sites are ok.
I got up at daft o'clock and parked in the same car park as Kelvin just after 5am, no problem with leaving after a walk round Old Portsmouth and a stroll along Southsea and a cuppa. I also wondered why they kept referring to her as HMS?
