Feature request: QUICK BOOT-TIME SCAN on START-UP

Avast Free Antivirus / Premium Security
1

I have several of the 500 million XP PC’s still operating. As the 4/8 patch expiry approaches, I’m increasingly concerned as numerous security gurus preach doom will befall these PC’s as hackers reverse engineer future patches and exploit XP’s vulnerabilities. Running a full boot-time scan takes a long time, but perhaps a QUICK BOOT-TIME SCAN on START-UP…combing features of the QUICK SCAN and the BOOT-TIME SCAN targeting most likely malware hiding places. Since the current quick scan takes 30" +/-10" perhaps tailoring the quick scan so it only scans changes since last scan or some other strategy that cuts the time.
Of course all this begs the question of whether a boot-time scan is really useful and effective. Malwarebytes, which I use for on-demand scans, doesn’t offer a boot scan because they say it’s not effective…they’re good at catching and killing bad actors as they act, not as they sleep.
A tutorial on Avast settings and use to keep increasingly brittle XP’s safe might also be helpful.
Thanks for considering my suggestions

You can select whatever area you wish for the boot-time scan… i.e. you don’t have to use the “All harddisks” setting.
If you choose e.g. “Auto-start programs (all users)”, which is offered in boot-time scan areas, it should be rather fast.

Thanks

The boot-time scan isn’t for that purpose, but a special scan, specifically if a malware detection can’t deal with in normal mode. Avast will normal suggest a boot-time scan after a detection in normal mode.

The boot-time scan is a one off selection, there is no option to run it every boot as it could be rather tedious on every boot. I believe it is for the above reasons it is a one shot deal. The real-time protection of avast! is running fairly soon after boot so you should be covered.

avast also runs a rootkit scan eight minutes after start-up.
