Hi there!
I use Avast 4.6 home edition. I tested a rogue website
When you click any link for a serial in that site, a rogue script is loaded that asks you to click YES or install a cab file or something. I was hoping AVAST!'s webscanner will block this from happening. BUT, SADLY AVAST! HAS NOT STOPPED THAT SCRIPT FROM RUNNING.
1. That is a valid request to install a 'cab file or something' being used possibly for malicious purposes, avast doesn't and shouldn't stop valid requests (that is not a script).
Which script blocking engine would you be referring to? The Home version doesn't have the Script Blocking, that is a function of the Pro version.
2. You the user are given choices, Yes or No or clicking the x at the top right of the pop-up window). If you chose Yes, it has to be based on 'is this correct use for the site in question and do you want to install it,' rather than curiosity or testing, especially if this is your main pc.
Personally I never chose No either, I use the x at the top right of the pop-up window, you don't know what processing action will occur for either the Yes or No buttons. For the most part No will close the window, but you never know.
Caveat Emptor - Common sense is your best weapon against many attacks.
