AVAST! Boot Scan question

Hi all,

I apologize if this has been asked elsewhere as I am a newbie in this forum. Anyway, I have the free edition on my Windows 8.1 system and would like to run a boot scan for the 2nd time… the 1st time I left it overnight and came back to the computer the following morning only to find that it was 28% complete and had stopped at a point to ask I was “sure” that I wanted to move the windows file to the chest. Prior to starting the scan I had selected the option to move suspicious files to chest with the hopes that the scan wouldn’t come to a hault – well, it happened anyway!

The issue is that I am only willing to run the scan overnight when I’m not using the PC, so I need to scan to run to completion without interruptions… I understand that it is a safeguard to prevent potentially harmful actions but don’t have the time to wait around (it’s SUPER slow). Any way around this?

Thanks in advance!

why do you run boot scan…any problems?..what was detected and what malware name did avast give
boot scan is not meant to be used as a regular scanner, but a special tool you use if avast have problems removing a infection…

it may also give you lots of PUP detections…
PUP = not virus / Possible Unwanted Program …so you need to be sure whats detected before you take any action

avast PUP scan is default off exept fo in boot scan

GUI>Scan>select “boot scan”>click settings>select “fix automatically”

Why are you running a boot scan? Did avast prompt you to run a boot scan?
I haven’t ran a boot scan in years. I have relied on either a weekly (scheduled) quick scan
or a monthly full scan. We do have a member who runs a boot scan right after a “major”
release. Other than that he rarely if ever runs a scan. But…to each, their own.
Personally I don’t see the need to run any boot scans unless avast prompts me to do so.

Telling him to select “fix automaticaly” can only come from someone that doesn’t understand, and use, the boot time scan.
This will most likely leave him with a non-bootable pc, because Avast has “fixed” a false positive Windows system file.
The “ignore” option should be used, if it still exist in the new crippled v2014. After a finished scan, look in the log and take eventually necessary actions.
And telling him that you do not use the boot-time scanner, is completely irrelevant to his question…

Hello hau5junkie87,

please give us more information.

What are your computer’s specs?
Which drive(s) and how many are you using? (HDD/SSHD/SSD)
Are there a lot of small files (documents, pictures) or more big files (videos)?
Can you run CrystalDiskInfo and show us a screen shot of all S.M.A.R.T-values from every drive you’ve plugged in?
(please expand the corresponding window so that we can see all raw/hex values).
On which file exactly did it stop?

if it’s stopping because of a detection, you might try to change default action to “ignore” so that you can check the logs first and ask for help in the viruses and worms section here.
Else, keep a look at your HDD LED in case it might hang without responding.
