Well, there's your problem. What are you doing that you need any antivirus past whatever security essentials is called these days and maybe malwarebytes?
Kaspersky is really good, it rarely blocks things. The bundle star games are labeled as phishing links - probably an issue with the website rather than the AV if this is the first block I've had in months.
