Got it, let's fix that annoying auto-linking issue you're dealing with in Sumatra PDF and Adobe Reader. Here's how to turn off that feature in each tool:

For Sumatra PDF #

• Open Sumatra PDF and head to Settings > Advanced Options (you can also press Ctrl+, to jump straight to the config file).
• In the plain-text config file that opens, find the line starting with EnableLinksFromText.
• Change its value from true to false, so it looks like: EnableLinksFromText = false.
• Save the file and restart Sumatra PDF. After this, the reader won't automatically turn plain text URLs like www.example.com into clickable links anymore.

For Adobe Reader/Acrobat #

• Open Adobe Reader/Acrobat, then go to Edit > Preferences (or use the shortcut Ctrl+K).
• In the Preferences window, select General from the left-hand menu.
• Scroll down to the Basic Tools section, then uncheck the box labeled Create links from URLs.
• Hit OK to save your changes. Adobe will stop auto-detecting and linking plain text URLs, so you won't get those pesky "unsafe link" prompts anymore.

A quick note: This is a global setting for each reader, not per-PDF. There's no way to disable this for just a single file—it applies to all PDFs you open with the tool.
