False Positive ? trojan warning pc "mytoolshed.co.uk", but ok on iphone

[bwdeng500]

I cannot get past a warning for Trojans when trying to access "mytoolshed.co.uk" which as far as I know is a legitimate site.  I called the firm and they are not having any issues.   I can access this site when using an iphone.  I cannot find any instructions on malware bytes to check the site or get this 'false positive ?" removed.  please help... thank you.
