'Virus of Unwanted program has been foun

[Loulou]

Everytime I come onto the site and at each subsequent page I go to when I am here I keep getting this warning

Virus or unwanted program has been found

I am using Avira and it says it is a Malware program.

It is happening when I go on the Horse and Hound forum too. I have notified them.

I keep getting warnings of Trojan Malware viruses - it says I have viruses on my computer and do I want to remove them and I keep just closing it down, then it goes away, I think telling it to get rid of them will cause more damage.
