Version 6.1.3.900(64-bit)1224 prevents access to many websites, saying they are not safe "The site ahead contains malware", although Chrome opens the sites with no warnings, and checking them online results in "Domain clean by Google Safe Browsing, McAfee, Sucuri Labs, ESET, PhishTank, Yandex, Opera" (for example mediagalaxy.ro). I get the same error even when trying to access the WordPress admin page (on all websites I have, with no exception).
Any idea why?
