AVAST 2014 FREE's USB Protection Sometimes Conflicts with SMADAV

Avast 2014 free offers automatic scanning of autoruns when attaching removable media like USB keys/flashdrives.

And SMADAV does quick scan automatically USB keys for all types of possible malware.

Sometimes when I insert heavily-infected USB keys, I observe that Avast and SMADAV conflict in cleaning or detecting malware. But nonetheless, ALL malware are removed.

To date, I have inserted five infected USBs.

SMADAV quarantined 44 of them - no false positives.

AVAST quarantined 8 of them - no false positives too.

Does that mean that SMADAV is faster and more aggressive in detection or removal? Or maybe because AVAST focuses only on autoruns.

Is SMADAV enough for USB protection and should I disable AVAST' USB protection? Anyway, enabling THEM both is just fine. ALL are caught by the way.

Anyways, I have diabled autoruns in any removable media, and disabled execution of processes/executables in removable media. For me, those settings are helpful enough.

 

Lol, had to search for this, never heard of Smadav before. Unless one of the AV's is designed to run alongside a second one, you should not install 2 realtime AV's.

Doesn't say much, it may also be affected by the order of installation or which AV starts up earlier at boot time.

 

Order of installation?

Boot time? I insert infected USBs only AFTER both are fully loaded and operational.

 

-Whether you installed Avast first and then Smadav or the other way around.

-With boot time I mean whether Avast's or Smadav's processes and drivers started first.

 

All the processes and drivers are all loaded and present, according to Task Manager.

 

Regarding SMADAV, it's basically like MBAM with a more limited scope.

Indeed, SMADAV is very aggressive. Too aggressive for my liking in fact.

Yes, they should be, I mean if if one was installed/loaded earlier than the other one, than they may intercept malicious things earlier so it doesn't have to mean they are more agressive.

 

Ok. Thanks.

Do you think it will be enough just to uninstall SMDAV and let Avast do it all? SMADAV caught higher number of malwares from USB.

 

Can't say. Blacklisting is hard to predict. In the future it might be that Avast! will catch more malware. SMADAV is designed to run alongside with your main AV. Although I'm usually against that idea, maybe it's okay to have them both running in real-time. Or you can disable SMADAV's real-time protection and just use it on-demand.

 

Agreed, use as you feel comfortable.
