These viruses may be dispersed via phishing email messages, contaminated downloads, or compromised software program updates.
Once a backdoor virus infects a program, it can:
Disguise By itself: Use approaches to avoid detection by antivirus application and procedure monitors.
Set up Persistence: Modify system configurations to be certain it continues to be active even after reboots or computer software updates.
