It may be impossible to guarantee that your computer, phone, or other devices have never compromised with malware.  Even trustworthy sources can become unintentional providers of malware.  Sometimes security flaws in software allow attackers to gain access to your computer resources, before the software supplier is aware of the flaw.  Exploitation of these flaws before the software manufacturer provides patches are called zero-day exploits (or zero-day hacks).  Additionally, legitimate software can be compromised either by direct attack on the publisher, or by a supply chain attack (in which, a third party is attacked, leading to the compromise of software downstream).
