Microsoft has said it is investigating the hacking of a small number of its computers - a breach which it said was "similar" to security intrusions recently reported by Apple Inc and Facebook.
Microsoft Corp, the world's largest software company, said the computers targeted with malware included some in its Mac software business unit, Reuters has reported.
The firm said there was no evidence customer data had been affected.
Apple is trying to identify the source of vicious malware attacks on a "limited number" of its Mac systems, a statement from the corporation said.
The corporation is to release new updated software to protect users and its systems.
Apple has revealed it has been targeted by computer hackers and will today release a software tool to protect customers against malicious software used in attacks.
The corporation says that there is "no evidence that any data left Apple" and that it is working with law enforcement personnel to identify hackers.
Facebook and other companies have also been targeted, according to Reuters.
