I have a quick scan scheduled daily at 6 AM and a full scan scheduled at 3 AM on Monday morning. This posed no problems in Avast 2014 Pro. I put in the update for Avast 2015 Pro and now my scheduled daily scan runs at 12 midnight and my weekly scan tried to run at 9 PM Sunday night. I checked the scheduling and it still shows my previous settings. What would make the scheduled scan run at a different time?
My apologies for the double post. When I clicked on the Post button the Forum page would not reload. I had to close the tab and open the Avast Forum again in another tab.

I've faced the same, asked here in forums, but couldn't solve my own issue. Hope we have more luck if more users point this up.

My last scheduled scan on Nov. 29, 2014 did not start at all.
I had to manually start the scan several hours later. ???
-
Similar situation here, within the last few months Avast scan seems to run randomly through the day, where the scheduled scan was working fine up to that point. On my Desktop machine it switches (again seemingly random) between running the scan at the indicated time local or UTC time. (i.e. it seems to random pick what time zone it wants to use, but runs the scan at the "appointed time")
EDIT: win 8.1 on laptop; win 7 on desktop
-
Ok, I changed both machines' schedules to run a quick scan at noon, neither did; at one minute after noon I changed both schedules to 1805, and they both started right at 1205. Not really expecting the same to happen tomorrow.

So Desktop did a shutdown after it's scan, and I started it up a little while later... and as 1805 swings around, it runs again... :(
Laptop has not re-run.
Just no predicting when the thing will run, it would seem.
And no word from support on it? Seems like it's been being reported on and off for years.
-
I'm running into this as well. I have a daily quick scan scheduled for 19:30 Mon - Sat and it scans everyday at 11:30 and 19:30. What's going on?
-
There is apparently a problem with the scheduling. It's been reported.
Curious why you want to run a scan daily???
Anything new, changed or updated is checked by the on demand scanner.
-
I'm adding my name to the list of folks with problems with the scheduled scan not running at its scheduled time. I had mine set for 22:00 and it fired itself up at 13:00 consistently. Going to set it for 13:00 and see what happens. I'd like to see this fixed though, having to work around an error in a service I pay for doesn't seem right.

I reported this "ages" ago (many times) with zero feedback......got finally tired of reporting with zilch feedback. >:(
Also, another bug is Avast's UI also pops up on screen after scan....scheduled scans used to stay minimized when done if all OK.
Also, some of the times you get a false "Threat Detected" even when Scan shows fine in history.
Bottom line, all the above seem to be faulty with Avast on scheduled scans.
So, only thing I can tell you on scheduled time....this happens with the "standard/default" scans.
I found if you create a Custom Scan (even if same settings as one of the default ones) you can schedule and it'll run on schedule.
I do a scan with Avast & MBAM Pro every morning at 4am & 5am before I wake up on all my PCs.....and they work on time.
You can see that while Avast & MBAM active shields work fine together I don't want the scanners running at the same time.
P.S. For those that have MBAM Pro and are/will do the same.....make sure in MBAM Settings of the Scan you uncheck "check for updates before scan" or it will also not run on selected time.....BUT unlike Avast, MBAM does acknowledge this is a known bug. If you are updating MBAM database throughout the day this is not big deal.

Yeah, it's disheartening that what should be an easy fix has been ignored for so long. It informs us of their exact level of care for their customers.

Let me know if creating a Custom Scan and scheduling it fixes the problem for you...it does me....all PCs run at exact time scheduled from a Custom scan.

It did not, so far only on my win7 desktop, the seemingly random (although I have a pretty good guess) switching between system time and UTC continues.
I will try the laptop now and see if it's behavior is altered.

In fact It's been going twice a day lately once at 2301 UTC once at 2301 local time, i.e. it alternates
It shuts down after each scan.
I suspect there is an array someplace they are expecting a scalar, and it is messing with their ability to tell time.
-
Same here. Schedule is set to run scan at 4:00AM on Sunday morning; runs instead at 11:00PM on Saturday night.

Has anyone tried a repair? ???

I’m going to put my two cents worth in.
I’ve been using Avast for some 4 years now and run a scheduled Full System Scan at 02:00 every day. This might sound excessive as others have pointed out but since I use laptops exclusively running a scan that reads all the data stored on your hard disk/s can give you forewarning of a disk that’s on its way out and allow you to get all your valuable data and software off before it goes legs up permanently. I do also do a full system backup every 2 weeks to an external drive but you can still save up to 2 weeks of work knowing you have a disk on the way out. It also minimizes downtime as it gives you time to get a replacement disk ready.
Anyway, back to the problems of the scans not running at the correct time. This has only been a problem for me since it was upgraded from the 2014 version to the 2015 versions and as far as I can tell it’s using UTC, GMT, Zulu, whatever you want to call it time and the log files state the UTC time and date not the local time and date.
I telephoned the call centre about it and as expected they told me to uninstall and then reinstall the software using a fresh download as Wi-Fi isn’t 100% reliable and the original update could have been corrupted. It’s pretty hard for a Wi-Fi link to corrupt a file when our in house network is all CAT5 or CAT6 cable running at 1000/100 Mb/s but the technical support person at the other end didn’t seem to understand that people do actually use extremely reliable, much faster and secure cable networks to connect to the internet.
Anyway I gave it a go just in case and as expected it didn’t fix the problem.
Having said all that, I never had any problems on the two machines I have used Avast on over the years until it upgraded from the 2014 version to the 2015 version, so for me at least it would appear to be some problem in the 2015 release.

I've had the problem on and off, but since the 2015 release it's been constant.
It sounds like, from your description, they are only interested in getting you off the phone, not helping, typical unskilled call center stuff. They get to record a call, and a solution, mark it closed and put a smiley face on their metrics; not doing anything and not helping. :(

Just tried it. Doesn't fix it. I'm running Avast Pro Antivirus under Windows 8.1. I have had this problem since November or so; the scheduled scan feature is completely useless.
-
@ Para-Noid,
It's a bug not something that can be fixed by a repair or clean install.
This is something Avast needs to tackle. :)
-
I am still running Avast 2014 which also has this issue.
On all my W7 64-bit machines I have created a CUSTOM "scan" (selecting the same scans items as the FULL) and in this new custom scan I go to its scheduler....and it works accurately (on time)....perhaps this solution (work-around) does not work in 2015 but wanted to re-post...may be worth trying.
-
So far the only difference in creating a custom scan go me was a slightly more regular wrong time, to the point I tried setting the schedule forward 6 hours so it would run the right time, and it tried running at the same wrong time :(
Avast is not reliable. If they cannot even get a schedule right why should I believe it can keep a virus out of my computer?

Maybe you should consider that the scans are actually there to make you feel better.
The built in shields really don't require constant running of scans once you know you have a clean system. :)

That might be reasonable, if they worked. Why would I think the scans, or shields, are working when something as simple as scheduling doesn't?

If you don't think the shields are working, why are you using the product ???

Same thing for me. These scans are not only irritating in them slowing my computer down in the middle of my workday but they then happen randomly it seems in the middle of the night. I have tried to change the settings to the computer won't auto-reboot when scan is done and it's like I did nothing. Avast always reboots my computer after a scan and does not close down my programs correctly. SPECIFCALLY OUTLOOK. If my computer reboots with OUTLOOK open, it then needs 30 minutes to as much as 2 hours to "check for errors". I had to have all my email forwarded to a dummy gmail account so I could check it since this happens so often.
NOTE TO AVAST: I'm lovingly looking back to the old days of NORTON and MCAFEE. At least their software was not riddled with bugs like this. If basic things don't work right, who is to say your VIRUS protections are up to date? How can I trust your software to protect my computer? I'm moments away of going back to McAfee. Really.

@ Bertdanger
Ah the good old days - when on-demand scans were more of a necessity than they are now.
With a resident on-access antivirus like avast, the need for frequent on-demand scans is much depreciated. For the most part the on-demand scan is going to be scanning files that would be otherwise be dormant or inert. If they were active files then the on-access file system shield would be scanning them before being created, modified, opened or executed.
I had previously avast set to do a scheduled weekly Quick scan, set at a time and day that I know the computer will be on. But I have stopped running on-demand scans.
Who is to say your definitions are up to date - well to start with you not only have the virus definitions auto update but also the streaming updates - I received 318 of these during the last 24 hours. Then there is the other quandary if as you say the virus definitions are out of date how is an on-demand scan to detect them either, this is no different with any antivirus.
That said this problem needs to be resolved (it worked very well with previous versions) or it is pretty pointless offering scheduled scans if they don't run as scheduled.
-
New version of avast released 2015.10.2.2214, try that and see if this issue has been resolved.
-
Well, dog my cats!!
Looks like it's fixed!
Working for me under Win 8.1 64bit with Avast Pro
Thanks, Avast! tech support or whomever.

I have 9 machines, and they all have the same problem: scanning at the wrong time. The problem is that the scan used so many resources that some of the older machines can not get out of the screen saver for 20-30 seconds, if at all. Whenever I can not get to the log in screen from the scrren saver it is always the damn scan running. I usually turn the workstations on at 7:30 am. The scheduled scan is for 13:00, but the scan usually automatically starts around 9:00. Total pain in the ass now because it is killing productivity, and as a Network admin, I have to listen to all my employess complain that their computers are slow, frozen, or malfunctioning

It does sound as if Avast thinks you're 4 time zones east of where you are, so 0900 your time would be 1300 there. If everyone who reports this would also include their times zone, it might be clearer. Someone did mention it fired at UTC rather than local for them...
-
a alternative for some may be to activate screensaver scan, then you dont have to think about shedule
rember that avast have realtime scan (all AV have that) meaning evry thing that happens in your comp when on is checked in real time
