URL: Mal avax.com search

Hi guys, this is my first post here.
I’ve been running for a week the trial version of Avast IS (without Avast firewall, it couldn’t be installed). Now, every time I try to use the www.avax.com search feature, Avast pops a warning, for instance"URL:mal blocked.Object:http://avaxsearch.com/images/autor.gif .Processus: C:\Program Files\AVAST software\Avast Svc.exe"

This is what I’ve tried so far: -run Avast full scan -run Malwarebytes full scan -flushed temp files with TFC -run Microsoft Safety Scanner, and they find nothing infected.Could this be a false positive ? Thank you for any help you can give me.

what AV did you have before installing avast ? have you removed it ? did you run a removal tool to remove any leftovers ?

The URL:mal is bc you are trying to connect to a website avast does not like…so it is not something in your computer
however checking that URL…Sucuri / URLVoid / UnmaskParasites / VT…all say clean, so it may be a False Positive

Thank you for your answer Pondus.

Before installing Avast Internet Security, I had Avast free version, and I did remove it beforehand, but I didn’t run any removal tool.

Thank you for checking the URL, and I’m happy that is clean.
It’s funny, but if I run the browser (Opera) in Avast Sandbox, Avast doesn’t give me any warning on the URL in question.

and what did you have before avast free ?

if there are any leftover files from previous installed AV it may create trouble…avast seems to be very grumpy about these

Before Avast a had Norton, and I run Norton uninstalling tool after uninstalling it with Windows Add Remove Programs.

I tried to repair Avast from Windows Add Remove programs as you suggested, but it didn’t solve the firewall problem.

I then run the Avast uninstall utility, rebooted and reinstalled Avast, but it failed to install the firewall again.
