It's now possible for a "rogue" website to actually embed
trojans, worms and/or viruses directly into a web page. In
the past, pages that offer seemingly attractive downloads
which contain such malware required you to click to start
any download to your computer. Now it's become automatic,
using features in the Windows operating system known as
scripting. These scripts can load programs without you
knowing, and then they run immediately. All you have to do
is visit the site, without doing anything besides viewing
the page.
HTAstop acts as a brickwall against these scripts, disabling
them so the download doesn't occur. HTAstop protects you
against one variety of script, our IEClean 5.50 covers all
twenty seven.
