Vista Home basic install of Avast - 4Home

Is there a special sequence to follow for installing Avast on my new HP 550 with Celeron processor or what?
when I try to install it, it will scan the memory and then disappears with no control panel. Any suggestions?

No not really. I have it running on an HP DV 5527 and the install was straight forward.

Well you will have to expand on that. Now after installing avast, when you start it, it does a start-up scan then goes into the main window. Is this what you mean?

Hi mmarti2x!

Did you use any other antivirus application on that pc before?
Do you use any other security software beside avast!? (antivirus, antispyware, firewall,…)
