Connection to a particular remote server blocked by antivirus?

Avast Free Antivirus / Premium Security

Hello guys, I’ve got new credentials to renew a license based text translation software (WordFast CAT Tool). I’ve been using the tool with connection to client’s remote servers (translation resources) without any problem up to now. Once new WordFast license key is introduced, connection to client remote servers is lost, disabled ( “IO error occurred. Network exception” ). Using different CAT tools (e.g . SDL Trados) remote server connection is OK, instead. Now, incredible thing to me is I cannot access any public site if “WordFast” is included in URL (whatever Chrome or Firefox is used). May the antivirus be involved? How to fix it? OS Windows 10 + Avast Free Antivirus 19.5.2378 Thank you

You don’t mention the OS your on and build or the Avast Anti-Virus product and version you are using.
