Avast anti-virus: how to install Charting Companion

Avast anti-virus incorrectly detects ACFPDFUI.DLL as a "virus" and deletes it. This is called a false positive.

To install Charting Companion on a system protected by Avast, you need to temporarily suspend Avast.

Click on the Avast icon in the System Tray (bottom right) to open up the Avast control panel. 

Click on:

1. Settings

2. Active Protection

3. File System Shield

4. Turn off for 10 min or 1 hr. (button at right)

5. Install Charting Companion

6. Click on General, Exclusions, Path, browse to:

C:\Program Files (x86)\Charting Companion

and select.

7. Turn back on Avast File System Shield
