My old security sw use to run at a certain time in the day (e.g. 2am). Does bitdefender auto run on a PC or IOS? If 'yes'... how do you set it up? Is running bitdefender in batch mode overkill?
System requirements to run Bitdefender on all operating systems (Windows, macOS, iOS, Android): https://www.bitdefender.com/consumer/support/answer/28539/
Set up scheduled scans in Windows: https://www.bitdefender.com/consumer/support/answer/2056/
Additionally, for iOS, there is no anti-malware scan available due to Apple's restriction policy on its operating system, hence there is no schedule scan available.
