:slight_smile: Hi Lenjam :

 You should NOT be running a "boottime" scan everytime you start your computer, because
 Avast has 7 "Providers/Shields" that do  a very good job of providing protection. However,
 that does NOT mean you should NOT have several antiSPYWARE/antiTROJAN program(s)
 and a good software firewall on your computer.
