| MS update skips polluted systems |
A kernel update was found to be inserted in Microsoft Corporation’s newly-released update, which does not allow the installation once a rootkit is detected on the computer system that is supposed to be updated.
Safety measures in avoidance of similar negative events
The company created the patch this way for the sole purpose of avoiding the same event that happened on their previous patch last February. In that preceding update, Blue Screen of Death and the incessant rebooting of the computer system occurred on the computers that are being operated by Windows XP.
Microsoft Corporation received quite a number of disapprovals due to this undesirable occurrence. After that, the company was able to conclude that the there is a connection between the Windows kernel security patch and the Tdss rootkit that was certainly difficult to be identified.
Good and bad codes clash and halt installation
Rootkit, a recently-discovered malicious software, works by trying to hide from the watchful eyes of the installed anti-virus software. Thus, these malwares hide within the codes like the Windows kernel.
So as to avoid similar incident as that of what happened in the month of February, Microsoft Corporation made use of a technology that is generated in such a way that it can stop the installation when there is a malware detected in the system being updated.
Shady activities in a system act as a signal
Microsoft described the new technological advancement in the FAQ for the MS10-21 patch. It was said that the security patch contains a package-detection logic that thwarts installation on a computer when there are suspicious activities working within the systems.
In addition, the suspicious activity can possibly result from a latent infection created by a virus, which works by altering the important files of the operating system. Hence, this leaves the computer incompatible for the kernel update.
MS10-15 update, an altered edition of the patch, was also created with similar technology as the one stated prior. This was distributed early in the month of February. It was, then, modified in the middle of March with the kernel that prevents installation on affected computer systems. Consequently, an error code will appear if the individuals try to install the modified versions of MS010-15 or MS10-021 package of kernel update on their malware-damaged computer systems.
