Deadliest spyware as of 2007

One of my clients got this, IE-AU PS, spyware on his laptop. I've done an extensive research on this subject matter, have tried every anti-spyware on earth, nothing came up, a day later, took the last step, reformatted the whole hard drive, but somehow this spyware made it through, and still exist somewhere in the computer.

According to this anti-spyware, "CounterSpy", this is a password cracker/stealer type spyware, but for some reason it didn't detect this.

Symptom: Whenever I go to "my computer", click on anyone of the drive and open it, another internet explorer desktop icon will appear with some random website setted as the homepage.

Anyhelp would be greatly appreciated!

This is from a fresh install on a formatted drive? Is this without ANY web browsing activity afterwards?

There are two main ways that the PC is getting re-infected:

1. It is a virus that spreads via LAN-type means and is getting attacked by another computer on the LAN that is still infected but noone knows about (or noone is admitting to, this is common too).

2. The person is browsing to a site that is re-infecting it again, at which point you can look in their browsing history to narrow down the infected site.

Good luck!

The problem here is that it's probably a well-known infection - but Sunbelt Software (CounterSpy) have given it a name not recognised by other security vendors. It may be worthwhile running a scan with other programs / facilities, such as Housecall, Panda Scan, Superantispyware, Prevx1, etc, just to see if it goes under a different alias?

Have a read of this Thread....it'll get you going in the right direction in regards to cleaning it off the computer.

Thank you for all of your help, guys. I will take your great advices and see what will happen next. Thanks again.
