Boot Scan Greyed out

Hi,
I just got a new desktop running windows Vista and when I run avast the “boot scan option” is greyed out. I have read about this issue on older OS. I have Avast running on my laptop that has vista with no problem. Any ideas?

There is no Boot scan if you have 64bit OS… :cry:

Yet…

It is being worked on…to possibly have it available in version 5.1 IIRC

Hi All. I just posted this question previously. Avast is supposed to have 64 bit support so why does it not provide boot scans? Can I get a boot scan program from Avast. I did a scan already and caught two bugs…one trojan and one worm I believe it was. I would like to schedule a boot scan. Thing is I’m not sure I need it. I don’t use pirated software and I have my boot settings on the one drive.

Thanks

Jones
