I have had an experience that I have never seen before. Can anybody give their opinion on what exactly it is and if they have come across it. On posting in another Forum (not a computer Forum), random words become highlighted in blue. If you click them, an ad pop-up about cigarettes comes up and if you go to the site it is about tobacco and cigarettes. This occurred even in one of my posts. A screen-shot is :- Two of the sites are :- -vapour-exposed.co.uk- -skycig.co.uk/special-offer1/lp/- Is it a virus ? I am not trying to solve another Forum`s problems via Wilder`s, I am simply trying to satisfy my own curiosity as to what this strange behaviour is. No need to be precise, just say whether it is a virus infection I have come across for my own education. I have already told them it is a virus and to get it sorted out. I will not be going back on the issue.
