I'm being falsely redirected from a site. 2nd time it's happened

I subscribe to OurTime.com.  I get fake emails that claim to be from them, but aren't.  I wrote OT and they asked me to forward them one of the fake emails.  When I tried to do that, I immediately lost the ability to access OT and was ALWAYS redirected to OurTime.co.uk.  A GREAT AVG tech solved that by phone, but it's now happening to me again.  Can you please teach me how to fix it myself?  Thanks! (Running AVG virus scan, I come up 'clean'.)
