I guess you are at the avast anti-virus support forums because you can't get to trendmicro, sorry couldn't resist.
Check your HOSTS file C:\Windows\HOSTS no file type/extension, you can open it with a text editor like notepad, etc. look for any URL for trendmicro and 127.0.0.1 on the same line this is trying to divert and attempt to get to trend and say the content is on the localhost (your system). If you find any of these and other security based URLs, I suggest you save a copy of the HOSTS file to a temporary location before you edit out (delete) these trend 127.0.0.1 lines in the original file, save and exit
