[Website blocked due to a suspicious top level domain (TLD) Website blocked:]

I am trying to install "DesignSpark Mechanical" from  https://www.rs-online.com/designspark/mechanical-download-and-installation. When I click the link to  from: auto.designspark.info, I receive the TLD block. Is there a way to determine if this block is due to not many uses or due to some malware?

Thank you  - I removed MediaWidget app and disabled BSD Application Updater. This seems to have resolved the issue.

 

[Website Blocked Due to Trojan]

I use Malware Bytes Premium 3.8.3.My computer runs Windows 10 Pro and uses Eset 12.2.23.0 for AV. 

Beginning on 09/18/2019 I began receiving a "Website blocked" Type Outbound, Category Trojan to 52.3.64.241:57801 every 1.5 hours. I have attached the text notification from MalwareBytes. I have run AV scans in admin mode and Malwarebytes scans with everything coming back clean. 

52.3.64.241 comes back as registered to Amazon but the domain is listed as ws.bootstrapdevelopment.com. I am unsure of next steps and if I should be concerned.
