problem with html:hideme-f[trj]

I am running chrome and opera on a macbook pro using mavericks. A rivals.com (div of yahoo sports) college basketball site (private pay site) that I have been a member of for over 12 years and visit daily, now generates an avast warning for infection involving html:hideme-f[trj]. Today is the first day this has ever happened. Only members of this private group that are also running avast have been affected. Is this a false positive and how can I stop the incessant pop-up warnings?
Appreciate any help.

Having the same problem using Firefox, only my access is blocked completely.

site is infected with HideMe spam + iFrame http://sitecheck.sucuri.net/results/rivals.com

Same problem with all Rivals sites. What’s the deal? Is it Avast or is it the site problem?

read my post above …

There are no safe site on the net … safe today may be hacked tomorrow

at the moment only Sucuri and avast is detecting the spam

Pardon me if this question is pretty basic, but is the solution to this issue is to wait for Rivals to fix it on their end?

yes a site owner problem …

Thanks for the quick response!
