Avast 'malicious URL blocked' pops up every time I open Google Chrome (annoying)

[Hankysan]

Could somebody advice me what to do with this nuisance pop up by Avast which says 'Malicious URL blocked' every time I open Google Chrome web site, although it doesn't do this with other websites? Only with Google every time I go to check my emails or search for info/images. It's really annoying and if I click on 'details' it would automatically redirect me to the 'Welcome to avast! Community Info Portal'. Has the Google URL been somewhere automatically marked as malicious and I need to look into some settings? I already tried, but didn't find anything related........
Thanks for any advice....

To avoid using multiple post with copy and paste you have to attach the log`s
Lower left corner: Additional Options > Attach ( Malwarebytes log / OTS log ) save OTS log as ANSI

Essexboy will look at the logs when he logg in today...
