Abstract: Methods, apparatus, systems and articles of manufacture are disclosed. An example apparatus includes at least one memory, instructions in the apparatus, at least one processor to execute the instructions to, in response to identifying malicious data: a) in response to determining that the at least one processor is controlled by the first operating system type, block a download from being executed, and b) in response to determining a switch from the first operating system type to the second operating system type, remove, from the at least one memory, an object downloaded in the download.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed. An example apparatus includes a detector to detect a user-initiated switch between a closed operating system type and an open operating system type; an adapter to, in response to a notification, from the detector, of the switch, transition activation from a first interface to a second interface; and a scanner including a first scanning engine to operate via the first interface when the detector detects that the operating system is in the closed operating system type and the second interface when the detector detects that the operating system is in the open operating system type.

Abstract: A technique for improving the installation of anti-malware software performs an analysis of a computer on which anti-malware software is to be installed prior to complete installation of the anti-malware software. If the analysis determines that the computer may already contain malware, then an attempt may be made to scan and clean the computer prior to the installation of a portion of the anti-malware software. Otherwise, the pre-installation scan and clean may be bypassed, allowing the installation of that portion of the anti-malware software.
