How to do computer setup scan??

Ive just installed avast home for the first time ever (family friend said it was a great program to use & i trust what he says as he runs & owns his on computer company) Anyway the first time I used it I had to restart my computer so it could do a full scan of my pc during startup. It got as far as 30% before my whole computer froze & i had to restart it >:(
I would love to get it to do another scan during startup but it wont. How do i get it to so?? ???

(sorry bout how i asked this question, im not very good at explaining myself :stuck_out_tongue: )

Thanks for any help!!!

The log file of the boot time scan should be located here:

C:\Program Files\Alwil Software\Avast4\DATA\log\aswboot.txt.

If you can find it, please copy and paste the contents. (You could also search for aswboot.txt.)

To run a boot time scan with avast! Right click the scanner screen, select ‘schedule a boot time scan’ and reboot when requested. (Or open the tab at the top left of the scanner screen and select the boot time option from there.)

Thanks for the help. AM going to try it right now ;D
