Security Software Vendors for Windows and Mac computers

There are plenty of computer security software companies offering solutions for protecting home, office and business (small, medium and enterprise) computers. Some security software vendors provide free security software with limited functionality and support.

Different antivirus vendors use different techniques for detecting and repairing computers with malicious software infections. They implement different methods of protecting PC’s by providing signatures and heuristic and cloud-based detections. Others include community-based and Host-based Intrusion Prevention (HIPS) to report a malicious or suspicious activity in the computer or network. A number of security software vendors also include a sandbox mechanism, allowing users to run applications in isolated or protected mode.
