Is ashquick really a good idea at startup or no ?
I think it is not. Why? Windows does not load all applications/services in the same sequence each time you boot. Lets say you have one harmfull thing loading and the rest is legitimate. You boot your system and ashquick, finds it. You boot again and ashquick doesn't find it because the harmfull thingy loads this time after ashquick.
What you should do than? That is up to you ofcourse. I would say have the resident scanner on all the time as well as the other providers within Avast. Depending on your surfing/download behaviour and how you have setup the rest of the security, I would say 1 full system scan or boottime scan once a week. And in addition to this a full online scan every 2-3 weeks. Also use Ad-Aware and Spybot S&d once a week. You can, if you wish, automate this with taskmanager and/or a batch file if needed/wanted.
I hope this info answered your question. If not, let us know.
