Firstly 5.0.377 was a pre-release version, the latest version is avast 5.0.462, so I would suggest that you update your program version. Since this is a pre-release version and since you also can't seem to use the update function (not advised in a pre-release versions anyway), you should do a clean reinstall.

Download the latest version of avast, 5.0.462 http://files.avast.com/iavs5x/setup_av_free.exe and save it to your HDD, somewhere you can find it again. Use that when you reinstall.
Download the avast! Uninstall Utility, find it here ensure you get the version5 one (it has uninstall tools for both 4.8 and 5.0), aswClear5.exe and save it to your HDD.
  • 1. Now uninstall (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 5.0, once complete reboot into normal mode.
  • 3. install the latest version, reboot.

I take it that you now have the latest version and updates are working as they should ?

Thanks DavidR for your prompt reply.

But the fact is that when i installed Avast second time, 5.0.377 was the latest version which i downloaded from Avast site  and when i tried to install then, i received message "beta version is expired". So i installed it back dated and could not receive update till now.

I will try downloading latest version shortly and intimate you about the status.


Thanks indeed.

Well I don't know when you downloaded it again or what link you used, but the first regular release version (not beta or pre-release) was 5.0.418 and that was about 8 weeks ago, with 5.0.462 about 3-4 weeks later.

I too am having problems updating the program/virus definition after I upgraded from 4.8 free edition. The firewall is correctly setup, tried uninstalling it in Safe mode, reboot, new installation but same error. Have also used the uninstall apps mentioned in this forum (aswclear5.exe) but still didn't help.

Im running out of options and patience, what good is the new GUI if the virus def cannot update. My system runs on W7 64bit, Avast version 5.0.507.

Anyone solved this issue?

Thx y'all.

This is a known issue. There are some suggestion on the forum but not always working.
