I have received a malaware warning on a site that I have paid to join, because of this warning I don't feel confident to access the site any longer. How can I see if the site is safe/protect my pc?

If a malware warning comes up on a site I reguarly use and subscribe to how can I protect my pc and still access the site or contact the site holder to get the problem rectified?

There was a link to google web checker and they said that they hadn't been on the site for over 90 days and they did not see any threats however, the malware warning keeps coming up when I try to access the site.
