Chrome自動(dòng)下載文件通常由環(huán)境中的觸發(fā)因素導(dǎo)致，常見原因及解決方法如下：1. 網(wǎng)站彈出窗口或自動(dòng)下載腳本可能在用戶無操作時(shí)啟動(dòng)下載，可通過阻止彈出窗口和使用下載提示來應(yīng)對；2. 後臺擴(kuò)展程序可能引發(fā)自動(dòng)下載，建議通過隱身模式測試並禁用可疑擴(kuò)展；3. 下載設(shè)置配置不當(dāng)可能導(dǎo)致文件自動(dòng)打開，應(yīng)啟用“每次下載前詢問保存位置”並檢查自動(dòng)打開的文件類型；4. 惡意軟件也可能導(dǎo)致此問題，可運(yùn)行Chrome清理工具或使用殺毒軟件排查。多數(shù)情況下檢查擴(kuò)展和權(quán)限即可解決，否則需重置設(shè)置或掃描惡意軟件。

Chrome keeps downloading files automatically usually because of one or more triggers in the browsing environment. It's not always a bug — sometimes it's how certain websites are designed to work, or there could be extensions or settings behaving unexpectedly.

Here are some common reasons and what you can do about them:

1. Pop-up or auto-download scripts on websites

Some websites use scripts that trigger downloads without direct user action. This is common with file-sharing or media sites trying to speed up access, but it can also be abused by less reputable ones.

• What happens : You visit a page, and without clicking anything, a download starts.
• How to check : Look at the bottom-left corner of Chrome (or the download bar) to see which site initiated the download.
• What to do :
  • Block pop-ups: Go to Settings > Privacy and security > Site Settings > Pop-ups and redirects , and make sure they're blocked.
  • Use Chrome's built-in prompt: If you see a download starting, hover over the download bar and click the three dots > "Always block on this site".

2. Browser extensions running in the background

Extensions like download managers, ad blockers, or even malicious add-ons can initiate automatic downloads.

• Why it happens : Some extensions are designed to fetch files automatically when certain conditions are met (eg, grabbing images or videos from pages).
• How to test : Open Chrome in Incognito mode (which disables most extensions), then visit the same site and see if the download still starts.
• Fix options :
  • Go to chrome://extensions/ and disable or remove any suspicious or unnecessary extensions.
  • Check for unfamiliar names or ones you don't remember installing.

3. Misconfigured download settings

If Chrome is set to automatically open certain file types, it might look like a download is happening on its own — especially with PDFs or media files.

• Common behavior : Clicking a link opens the file directly instead of prompting you to save it.
• To adjust :
  • Go to chrome://settings/downloads
  • Make sure “Ask where to save each file before downloading” is turned on
  • Also check the list under “Downloads” to see if any file types are set to open automatically

4. Malware or unwanted software

Unfortunately, automatic downloads can also be a symptom of malware or potentially unwanted programs (PUPs).

• Signs to watch for :
  • Downloads happen even when you're not browsing
  • The files downloaded are random or unknown
  • Your homepage or search engine has changed without your input
• Steps to clean up :
  • Run a scan using Chrome's built-in cleanup tool: Settings > Privacy and security > Security > Clean up device
  • Consider using Windows Defender or another trusted antivirus tool if the issue persists

It's usually not Chrome itself causing the problem — it's something interacting with it. Most of the time, checking your extensions and site permissions will resolve it. If not, resetting Chrome settings or scanning for malware should cover the rest.

基本上就這些。
