What about if that particular site had been hacked David ?

http://biggeekdaddy.com/AvastAVProtection.html

HTML:iframe-inf code alert. Big Geek Daddy uses Avast Anti Virus and found two legitimate websites that had been infected with an Iframe code.

Avast identifies this as HTML:iframe-inf. I don’t believe this is a false positive and if Avast or whatever Anti Virus Protection you are using gives you a similar warning then follow the prompt to abort the connection.

You might also consider sending an email to the website owner letting them know what page you encountered this on as they are probably unaware that their website has been hacked and infected with malicious code. Legitimate websites do get hacked unfortunately.

I did email KAT and that is when I found out KAT was getting reports from several of their members who use Avast reporting the same problem.

I have one thing to add and that is I re-installed Avast on Saturday, October 08, 2011, 10:30:49 PM (South Australian day light saving time) so unless there was an action by another party on the internet at precisely that particular time to coincide with my re-installing of Avast I cannot think of any other explanation why my re-installation of Avast worked for me.

Is there anything in Avast that stops script files ?

I did not alter Avast after the re-installation but the script shield shows no activity from the KAT site now.

I have emailed KAT to find out if KAT has blocked script files (ads)and if so when.

I do not get any ads at the moment from the KAT site and I do not use an ad blocker.
