Avastのソフトウェア更新が出来ずに困っています。
設定＞更新よりソフトウェアの更新を試みたところ
「何らかの問題が発生したため、アップデートが失敗しました。もう一度お試しください」とメッセージが出ます。
何度か試しても同じメッセージが表示されるのみで、更新が出来ません。
ウイルス定義は知らずのうちに更新できているのか
「ウイルス定義は最新です」との表示がされるのみです。
バージョンは19.7.2388、ビルドは19.7.4674.537です。
対応策がお分かりになる方、ご教示いただければ幸いです。
なお、情報が足りない場合は出力方法など教えて頂ければ追加で記載いたします。
よろしくお願いいたします。
一度Avastをアンインストールの上、再度インストールを行ってみてはいかがでしょうか？
こんばんは casper.genki さん
hamabe.server さんの書かれているとおり再インストールを試してみるか、あるいは単に上書きインストールでも直る可能性はあります。
一応、以下の２つのログの最後の30行くらいをこちらに添付(あるいは貼り付け)してもらえますか？

申し遅れましたが、プログラムの更新が出来なくなったのは今回が初めてではなく、出来なくなってはアンインストールして再インストールをしています。
プログラムのアンインストール＆更新を手動で行うのを１年程度繰り返したのちに、これはさすがにフォーラムで聞こうと思い質問したという経緯です。
このログを見る限り最後にやったのは8月25日のようです。長くなりましたが、よろしくお願いいたします。
ログを見る限り、正常終了したと言っているので、おそらくウイルス定義の更新か何かのタイミングのログになってしまっているようです。
アップデートに失敗した直後のログがあれば、そちらを見せてもらえますか？
ちなみに、以下のファイルのプロパティ → 詳細 の「ファイルバージョン」は何になっていますか？
C:\Program Files\AVAST Software\Avast\AvastSvc.exe
今のところ、確かにプログラムのバージョンが古いままになっている(同時にセットアップシステム側はなぜか最新になっている)のが分かります。以前にも1回似た相談があり、次回更新まで様子見となった記憶が・・・。

以上がプログラムの更新をかけた直後のUpdate.logです。
ちなみにSetup.logは前に貼った状態から変更はありませんでした。
ファイルバージョンは19.7.4674.0でした。
次回の更新まで様子見となったSubjectは私も見たことがあります。
確か同じような症状で困っている経験談を探したところ、そのSubjectを見つけて
私もいつか更新で治るのかなと思い、今日の今まで放置してみたといった状態です。
DNS resolve error となっていますので、ネットワーク周りのエラー（DNS による名前解決ができない）ですね。
しかも、ウイルス定義更新の際には正常なのにプログラム更新ではダメというところから、ファイアウォール等でアップデート用プログラムがブロックされている可能性が濃厚です。
ウイルス定義更新
プログラム更新
ファイアウォールは何をお使いでしょうか？
また、ファイアウォールを一時的に無効にすると、アップデートが通りませんでしょうか。
ファイアウォールはComodoFirewallを使用しています。
ファイアウォールを一時的に無効にすると、プログラム更新が通りました。
ファイアウォールがどういうわけかブロックしたログを残してないので気づけませんでした。
アップデートに使用しているプログラムはinstup.exeだとすれば、
80番、443番、53番ポートのTCPとUDPのアウトバンド接続許可をしていたのですが、それでは不足だったという事なんでしょうか。
更新に使われるのは instup.exe ですが、ウイルス定義の更新は常に同じパスのinstup.exe なのに対し、プログラム更新には別パスのものが使用されます。
パスは頻繁に変わるので、パスをワイルドカードで指定して許可しておかないと通信できません。
私もComodo Firewall (Comodo Internet Security: CIS)を使っており、以下のパスを許可として指定しています。
また、CIS の場合、各アプリケーションルールでログを記録する設定にしないと、ログが残りません。
C:\Program Files\AVAST Software\Avast\setup\*\instup.exe
提示して頂いたパスで許可を指定したところ、ファイアウォールを使用したままプログラム更新が出来るようになりました。
プログラム更新のうち、DNSへの問い合わせが、ファイアウォールにより阻止されていた事が原因で間違いないようです。
NONさん解決して頂いて、大変ありがとうございました。
Avastから若干離れた質問にもお答え頂き大変ありがとうございます。
おかげさまでプログラムの更新に苦労せずに済みます。
重ねて感謝申し上げます。
直ったようで良かったです。
また何かありましたらお越しください
