Ways to protect your PC from infected PDF files.

The first line of defense is to keep anti-virus software and Adobe Reader up to date to automatically scan and repair infected PDF files.

1. Switch Off Scripts:

In Adobe reader deactivate scripts in ‘Edit|Preferences|JavaSript’. In the menu item ‘Authorizations’, prevent the execution of external programs.

2. Use alternative PDF reader:

Since most of PDF exploits target Adobe Reader, an alternative like Foxit Reader is naturally more secure. Of course, this should also be updates regularly.

3. Online File Check:

Criminals send infected PDFs via email. To check such files, upload them with VirusTotal Uploader or use any other scanner.
