installing avast vista

Hi
Out of towne
Ijust removed an inactive Trendmicro and wish to install avast
I sent my brother xxx for dummies and set up a user account
how do i get to the administrator account
He is thinking that since his Internet provider provides Mcaffe he does not need an AV
lots to do here
he had the xp AV POP UP

yhis is an hp pavalion with all the toolbars
any idea how to get rid of the HP Yahoo search feature it is not identified

also
an AOL mail account
can I nuke AOL 9 and still use the mail he is not using the AOL for internet access

first scan with avast no hits
why does avast want to do the first boot time scan before updating?
here was a hit from MBAM anyone seen/ recognise this?

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Start_ShowSearch (Hijack.StartMenu) → Bad: (0) Good: (1) → Quarantined and deleted successfully.

for some reason it does not show up in quarantine

Check out this link from the MBAM forum. Posts 1 through 6 may help.

see anything we can slim down on this hp laptop ?
