Well, well. For those hoping to escape without need of boot time scan, be warned.
I had avast and Stopzilla running in Win 7 Pro 64bit all windows updates etc.
I scanned an exe, nothing found, ran it, and then nothing.
About a minute later a trojan/worm/spyware cocktail started hammering away at my system.
I disconnected, scanned, removed, rebooted and reapeated the process to no avail.
Tried repair. no good.
Tried system restore, nada.
Tried reinstall image, that was shagged too.
It got to the point that the system could not be accessed.
Whilst I was doing my scanning, I looked in vain for a boot time scan, the thing that might have saved me. Neither Avast or Stopzilla had one.
So that was the end of that OS.
I think we may hear a lot more stories like this one in the months up to an AV with 64bit boot scan support.
