From two months use Avast Home Edition and I am very happy.
I wanted to know if the program has the protection against the timeout (Outllok Express), when download enclosures of great dimensions ?
Thanks.
Of course: right click the icon > On-access protection > Internet Mail provider > Custom (sensibility) > Advanced > Timeout…
Please, if you have a dial-up, do not set to a low value or you could receive too many error messages from timeout feature. 
Wellcome on-board!
