A threat is defined as something that might do harm but once a threat happens do we still refer to it as a threat?
For instance, if malware infects our computer, do we still refer to the malware as a threat?

You may be looking for 'breach'. As described below, the original threat remains, a breach has occurred, and additional new unmitigated threats may exist where the attacker may be able to do additional damage now that they're inside.
Threat: the possibility that something could try to happen
Threat Actor: the person or other entity who will try to make the bad thing (threat) happen
Vulnerability: a hole in the design of the defenses that may allow a threat actor to cause a threat to happen
Asset: something of value
Exposure: an asset has been placed behind a vulnerability, thereby exposing the data to the threat
Exploit (n): the mechanism by which the threat actor will make use of the vulnerability to get to the exposed asset
Exploit (v): the act of using an exploit (n) to make use of a vulnerability to access the exposed asset
Breach(v): the successful act of exploiting a vulnerability. Breaching the defenses
Breach(n): the event during which a breach(v) occurred. A breach in the defenses.
incident: a detected breach or exposure. In some environments, a detected vulnerability, without an exposure
Mitigate: to reduce the severity of an actual or potential breach
Control something in place to mitigate, detect, or prevent a breach
Note that a threat that successfully breaches the security of some of your assets may not have successfully accessed all your assets, and may attempt to re-enter at a later time. Thus, you have a breach by an ongoing threat, with possibility of a wider or repeated breach, using one or more exploits to exploit one or more vulnerabilities that exposed one or more assets to the threat of a threat agent.
A threat has nothing to with a malware. It is basically a certain probability that an vulnerability gets exposed.
A malware is an exploited vulnerability by some kind.
