With so many attempts to upload viruses to computers and smart devices, it's always recommended that antivirus software be regularly updated and the latest definitions downloaded and installed. The many various types of virus attacks can create vulnerabilities to a secure server system and provide access to unwanted hackers to capture user info and passwords.The best advice I've heard is to never share login credentials with anyone even help desk personnel. They have access to fix issues without having personal info or login credentials through their security software.
