Having two AV's is a big no no.It can cause lots of problems,including error messages.Decide which one you want to keep,and remove the other.If you have paid for a new yearly subscription for Norton,it would make sense to keep it.If your subscription is due to expire,you may want to keep Avast.
Norton is notorious for leaving remnants,after removal,so they have a special removal tool available.
Regarding the logs,SAS found only cookies, nothing to worry about.
MBAM found some adware, and a few strange things.I would run MBAM again,this time fix the items, so they are moved to quarantine.
As for the HJT log, I see nothing alarming, although there are numerous entries for inbox.com ( toolbars and BHO'S ).I assume you actually want these things ?
Finally, I see no firewall in your log,are you using the windows firewall ?
It would be helpful if you said exactly what the error message is,also, to say what program removed the trojan, and the name and location of the infected file.Its not impossible that one AV has removed a file/s from the other.
