The Troubleshooting settings of Avast Business Antivirus policies include:
- Enable Rootkit Scan on System Startup—Normally Avast Business Antivirus scans for rootkits when the operating system starts to detect viruses that cannot be detected after startup. Unchecking this box disables the scan for quicker startup, but an active virus may not be detected.
- Enable Raw Disk Access during Avast Boot-time Scan—During a boot-time scan, Avast Business Antivirus uses a special method to access the raw data on the hard disk to check for potential viruses.
- Skip Checking of Digital Signatures of Infected Files—This refers to when a threat is detected in files containing a valid digital signature, including system files. When this box is cleared, Avast Business Antivirus reports but does not take any action for files which contain a threat but have a valid digital signature. This is cleared by default to exclude trusted files from being deleted or moved if a threat is detected. When this box is checked, Avast Business Antivirus takes action for all files containing threats including those with a valid digital signature.
- Activate Avast Self-Defense Module—Avast Business Antivirus contains self-defense features to prevent virus attacks from modifying or deleting critical antivirus files. Clearing this box turns off the self-defense and allows Avast Business Antivirus files to be deleted.
- Load Avast Services only after Loading Other System Services—Avast Business Antivirus service normally loads early in the boot process, but in some cases, this can slow down the system temporarily after startup. Check this box to delay loading Avast Business Antivirus services until after other system services load, but this slightly increases risk because your system is unprotected for a short period during startup.
- Limit Program Access for Guest Account—A user logged in to your computer as a Guest cannot access or modify settings for Avast Business Antivirus.
- Enable Hardware-Assisted Virtualization—This is a more secure way to launch virtualized processes. If this box is checked, potential threats opened in Sandbox cannot modify your computer or files.
