Looks like an exploit. Checks for security related things including versions and browser.

I’m assuming JS/Obfuscus.AACB!tr is when letter variables are used like this:


/*
a = b
c = b
e = c
if(a!=e) {
// do nothing
} else {
f = b
f += a
// etc...
*/

Hi folks,

Thanks for the representation, !Donovan,
This is being blocked by avast webshield as JS:ShellCode-AF[Expl]
Exploit is being blocked, we are being protected.
Furthermore in Fx NoScript will protect, for IE we can sett a killbit for that particular CLSID of the ActiveX-control,
