Their removal tool for this particular infection did NOT work either.
Panda also had a removal tool for the same infection, tried it, no more effective than ESET's.
MBAM found two more malicious items but the "attack" persisted.
Ended up having to use combofix to get it "right". He's now running ESET instead of MSE, as from the looks of things, it probably would have prevented the attack in the first place
That was Zero Access(0A). The "attack" was not really an attack, but rather the installed AV detecting an infected services.exe file. If the AV successfully deletes the infected services.exe file, then you will enter into an infinite boot loop because services.exe is essential for boot up. The installed AV should have been disabled to prevent it from removing service.exe and SFC /scanfile should have been run on services.exe to repair it. Then you should be able to reboot (assuming the 0A injector files were already taken care of). (The 0A files reside in either the Recycle bin and the windows/install directory or appdata/local and the windows/install directory). Also, 0A totally tubes 8 different Window services that have to be totally rebuilt. Yeah, I know what I'm doing, I've manually removed hundreds of 0A cases.
At any rate, Norton participated AV-comparatives in 2011 and did outstanding in their tests:
AV-Comparatives 2011 tests
AV-comparatives changed their testing methodology for 2012 and Norton felt it did not properly reflect real world scenarios, so they declined.
Norton did commission one AV-Comparatives test run in early 2012 and did very well:
Norton AV-comparatives 2012 real world mediation testing
In addition, AV-test.org did test Norton in 2012. Again, Norton did very well:
av-test.org 2012 AV tests
It is unfortunate that you choose to come on here and make a blanket statement about Norton based on a very narrow and limited experience with Norton. It is a much, much better AV than you give it credit for.
No, that wasn't it.
I've dealt with that one before too, this was slightly different in its methods and didn't actually replace the services executable, but rather was a windows service with a driver component (rootkit). Which required a bit more involvement to remove it. But it was removable.
I've dealt with a few of them myself, having been in the game professionally since the late 90's.
And to be clear, are you targeting me with the your comments about Norton or Mystic? I have my criticisms of all of the mainstream AV's and have chosen my favourite from the bunch based on my (extensive) experience with all of them. None of them are infallible, and I certainly don't condemn Norton for allowing something to slip past it, as that has been my experience with every single one of them.
