This seriously needs to be fixed in the program, not with various user-hacks. These are the kinds of foolish things that alienate users.
I’m getting this same error trying to update avast! Free from 5.1.864 to 5.1.889, on Win XP SP3. Never used a beta, never used a proxy; tried switching from “Auto detect” to “Direct connection”, which didn’t help.
Since I’m on dial up, I’m reluctant to try reinstalling if it’s not sure to fix the problem. Think this will be fixed soon? I think I may just wait.
All fixed, just got the update with no problems. That didn’t take long; glad I waited. 
Did not change anything and this morning Avast was updated automatically. Guess problem was not on my box after all.
It was acknowledged as a server error if your proxy settings were at Direct connection, it was corrected and should work on Direct connection or Auto detect again.
I have made sure all 3 computers I am using have settings set to no direct conection, set to auto detect, but am still experienceing problems when Avast Internet Security (paid for) tries to update (set to the default 240 minutes)
It comes up with the red error box, file not found in and either an http 412 or http 512 error.
There is something wrong with this latest version 5.1.889 or the Avast servers that needs to be fixed ASAP
Well the file missing error was related to the server issue, which was corrected anyway. But if you set them to Auto detect, that shouldn’t have been an issue either. So was that an early error before finding out about the cause I mentioned ?
I haven’t come across an http error 512 before and a google on it isn’t very helpful either and appears to indicate https isn’t supported, so I don’t see how that could be right.
The http error 412, is more common “HTTP Error 412 - Precondition failed” and I’m not sure what pre-conditions are checked for during an update or if it would fail.
Try a repair of avast. Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow.

Just tried that (again) on this computer, repair said Avast was successfully updated, but going to the update option I get the error message again:
other http error (412) while trying 174.36.159.202:80//iav5x/prod-ais.vpx
a ping of 174.36.159.202 says it’s a767sl.avast.com
I may be best to do a clean install on at least one system to see if that resolves it:
-
Download the latest version of avast AIS, 5.1.889 http://files.avast.com/iavs5x/setup_ais.exe and save it to your HDD, somewhere you can find it again (if you didn’t save your last download). Use that when you reinstall.
-
Download the avast! Uninstall Utility, aswClear5.exe find it here and save it to your HDD (it has uninstall tools for both 4.8 and 5.x).
-
- Now uninstall avast! (using add remove programs, if you can’t do that start from the next step), reboot.- 2. run the avast! Uninstall Utility from safe mode, first for 4.8 if previously installed and then for 5.x, once complete reboot into normal mode.- 3. install the latest version, reboot.
“Current Version: 5.1.889”
“Last encountered error: The system cannot find the file specified.”
Proxy settings: auto-detect. Also tried Direct Connection. No luck.
Log file sent to Vlk via email.
Tried the above on a clean test computer, only has windows 7 home premium installed, no other security software, or ‘user’ software. OS was a new install from install DVD
Downloaded both files, uninstalled avast using windows uninstall, ran Ccleaner, rebooted into safe mode.
Ran aswClear5.exe and removed Avast from system.
Rebooted into normal mode, reinstalled latest version from the downloaded file, rebooted. The shutdown took a LONG TIME. (approx 10 minutes)
Restart was OK but Avast immediately popped up the red error box saying it could NOT check/update the virus def file.
Tried a manual update, it took 4 attempts before avast successfully checked with the server and verified the latest def file was installed. the first 3 attempts failed with the previous error message (different IP this time, but still an avast one) “other http error (412) while trying 174.120.185.42:80//iav5x/prod-ais.vpx”
It’s obvious the ‘pre-condition’ the http (412) error is that avast isn’t getting a valid response from the avast server when checking to see if there is a new virus definitions file available or if it has the latest one.
COME ON AVAST IT"S ABOUT TIME YOU FIXED THE PROBLEM AT YOUR END!!! Getting your users to play around with all these supposed fixes on their computers is NOT WORKING and definitely NOT good customer service!!!
Your update servers are NOT WORKING.
I paid good money for this ESSENTIAL security application, you need to fix the problem your users are having ASAP!!!
thought it was just me. I get the same problem on both my computers. XP and Win7.
Only started happening this morning also tried playing with proxy settings.
Ive had any trouble with avast before and ive never installed a beat of prerelease
Still the same here as stated in other thread, have pretty much followed procedures as MaxLV has (seems odd all three of us are from New Zealand)
The only other factor I can think of is that ISP caching may be the cause. I’m with Telstra Clear/Paradise cable, and their caching servers have caused problems in the past with online updating, streaming video performance, and access to certian websites, but with the error only starting with the avast update to version 5.1.889 I dont think it is an ISP problem.
Here’s a part of the avast setup log with the latest attempt to check for a virus definition update:
I( certianly looks like an avast server problem to me:

I am with Slingshot ISP, i think it will just be a waiting game being the weekend. Not really in a position to complain as using Avast free unlike yourself
Snap - same issue in NZ using Telstra
This happened on the previous major Avast version upgrade, but I can’t remember what the fix was
Seems like we are finding some common ground here, though it is beyond me why it is happening.
I’m having problems with Avast’s update, too. Went through the update this morning early and got the error message. And yet when I check the serial number of my latest version, it shows 1.889 has loaded. I’m assuming that, despite the messages to reload, that I can leave it as is because, evidently, the new version is in place. I’m not going to fool around with it. Hope Avast will clarify what went wrong to reassure users!
(I use the Avast free version; Windows Vista; Mozilla Firefox.)
I am from united arab emirates… im also having problems like you guys do… it all happens this morning… when i opened my laptop, avast tells me that it encountered this “HTTP error(412)”…
