Sometimes Avast Antivirus may be stopping you from running a program or accessing web page, which you know is totally safe. Usually it’s because of the low application occurrence within the Avast community. Therefore, Avast can’t properly tell if the program is safe or not, and will try to protect you.

Unfortunately Avast is rarely also blocking a popular websites, games and services. Often when they release a new update/version which is not listed in the Avast Virus Definitions yet and it’s prevalence is really low.

Most often following programs, websites, services and games are being blocked – Google, Chrome, Gmail, YouTube, Facebook, Yahoo, Internet Explorer, Mozilla Firefox, Windows Update, Outlook, Skype, Steam, League of Legends (LoL), GoG Galaxy, Roblox, Hearthstone,, Minecraft, Dota 2, World of Warcraft (WoW), GTA V, RuneScape, uTorrent, BitTorrent, Java, Plex.

If it happens to you, don’t worry. We have a few simple tips for you how to unblock your favorite program or website.

There are two ways to unblock any program or website from Avast blocking. Please note, you should do it only if you are 100% sure the blocked file is safe for you and your computer. Even if you own the blocked site, doesn’t mean it wasn’t hacked and injected with dangerous malware. For checking the program/file with other Antivirus vendors, you can use online detection at VirusTotal. We also suggest to report the program/website as a false-positive detection to Avast.

1. Add Blocked Program or Website to Exclusion List (White-list) to Unblock it

Using the exceptions in Avast you can simply add any file or URL to the list of exclusions and exclude it from scanning and shield protection, therefore also from blocking. For more information about adding exceptions, check our full guide ‘How to Add File/Website Exception into Avast Antivirus 2017‘.
