avast won't find anything in the safesurf.exe file as the alert is to block access to hqtms.com, considered malicious by the network shield.
Safesurf.exe would appear to be something that you have installed, have you not googled that file name, I did and get lots of hits. It would appear to be a compdo product or incorporated into another comodo product, ring any bells ?
Though there are some hits relating to it being spyware, so find the file and check its file properties and se what it says about the Company, etc.
You could always upload it to virustotal.
