That's unusual, I've never had a drama with Kaspersky, it's got a very good name in anti virus and internet security but if no other finds anything I can only assume it's a false positive and ignore it I guess.
I used both work and home computers to access the site. There are no longer any problems and niether anti-virus programs picked up warnings on either system.
VP, maybe clear your temp/history files and cookies. Possibly you have a residue report.
Thanks David for solving the issue with the javascript error.
