avast! 7 & 6 Antivirus and Internet Security AutoSandbox

The avast! AutoSandbox feature is designed to run "potentially suspicious applications" in a completely isolated virtual environment to prevent malicious programs from damaging your computer system. Running CTI Navigator or CTI UpdateManager in the avast! sandbox "virtual environment" can prevent needed changes in CTI Navigator from being saved to your computer. The easiest way to configure the AutoSandbox in avast! to allow CTI Navigator and CTI UpdateManager to run normally is to select "Open normally" (do not select avast's default recommendation to "Open in sandbox"), and check "Remember my answer for this program" before clicking OK on avast!'s security warning screen.

5. Under "Files that will be excluded from automatic sandboxing", either type the full path to CTI Navigator; or click the browse button, and browse to where CTI Navigator is installed on your computer [typically C:\Programs Files\CTI Navigator\  or  C:\Programs Files (x86)\CTI Navigator\]
6. Select the CTI Navigator.exe file and click OK or press Enter. [Note. The ".exe" extension may be hidden until you change your Windows Explorer folder options to "Show Hidden Files or Folders".]
7. In a new box under "Files that will be excluded from automatic sandboxing" repeat typing or browsing the full path to the CTI Navigator folder
8. Select the CTIUpdateManager.exe file and press Enter.
9. Click the OK button to save these settings, and then close the avast! user interface screen.

• Select the CTI Navigator.exe file and click Open
• Change Allowed Connections to "All connections" as described in step 5 and 6 above.

avast!5.x Antivirus Real-Time Web Shield

avast!5 Antivirus does not usually need to be configured to work with CTI Navigator. However, if it does interfere with downloading MLS program and/or data updates over the Internet, avast's Web Shield can be configured as follows:

1. Open avast! User Interface.
2. Click "Real-Time" Shield in the left menu
3. Click Web Shield and either: 
   • click the Stop button to temporarily stop Web Shield, then click OK; or
   • click the "Expert Settings" button, and on the Main Setting screen either: 
     • click Exclusions (recommended) on the left > check "URLs to exclude" > enter ctimls.com in the box and click the OK button (see notes below); or
     • uncheck "Enable Web scanning" to permanently stop Web Shield (not recommended). 

Note a: If downloaded files are being corrupted, under Web Shield > Expert Settings > Exclusions > Main Settings, uncheck "Use Intelligent Stream Scanning". This sets downloaded files to be scanned only after all the parts have been downloaded and reassembled in a temporary folder, rather than being scanned piece meal as partial packets arrive. 

Note b: If Web Shield falsely identifies downloaded CTI Navigator files as infected, under Web Shield > Main Settings > select Sensitivities > click a shorter Orange bar to lower the Heuristic sensitivity. Unlike comparisons to known virus signatures, heuristics are just probabilistic estimates of the likelihood that a file may harbor a new unknown virus. 

By default Mail Shield will attempt to scan the content of  both incoming and outgoing email. To prevent unintended interference, you may un-check "Scan Outbound messages". To configure email accounts that require encryption, click the "Expert Settings" button and follow the instructions at https://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=842 .
