Mac 360 "MacKeeper" exposes Arbitrary Code Execution Vulnerability
I believe Mac users must have seen Mackeeper ads-a Mac OS system optimization software that integrates anti-virus, encryption, data backup, system cleaning, and software uninstallation, it can be considered as 360 of the Mac.On July 6, May 7, Mackeeper was found to have a serious security vulnerab
In the impression of many users, Apple Mac computer system virus is a lot of users do not pay attention to the problem, in fact, Apple Mac system is not safe, want to ensure the safe operation of the computer, the same need anti-virus software protection can be, and Mac OS x system antivirus software is also a few, which mackeeper is a very popular one, but some have not used MacKeeper anti-virus software u
When the CPU starts to process an interrupt (int4 ~ 15), it will reference the interrupt service table (IST ). Ist is a table that obtains the package containing the interrupted service code. The ist contains 16 consecutive packages. Each ISFP contains up to 14 commands (8 32bit nonheader-based commands or 14Header-basedCommand ). OneSimpleThe interrupt service p
Apple's Mac computer system OS X platform has a lot of anti-virus software to choose from, MacKeeper is one of the Mac antivirus software, then mackeeper how? is MacKeeper safe?

Usage of createevent, setevent, and waitforsingleobject in a thread
First, we will introduce how createevent is used to create a Windows event. It is mainly used to determine the thread exit and the thread lock.

Function Description:

In the ff_read_packet () function,
ret= s->iformat->read_packet(s, pkt);
Demux generates a package in

necessary, it would be possible to integrate the drive design (leave aside the division of the PDD-MDD, there is no need for ddsi ). That is, the existing driver architecture is not used for implementation. Considering that the use frequency and execution efficiency of the serial driver are not very demanding, it is not necessary to discard the driver architecture and implement it.For the driver itself, the functions and Implementation of the serial driver are quite simple, and it is indeed qui
=-\infty}{t\to \infty},\frac{k=+\infty}{t\to \infty}) $, which is $ (-\infty, +\infty) $. The value interval is $\frac{1}{t} \to 0$, tending to continuous variables. Now use continuous variable $s$ to represent $\frac{k}{t}$:$s = \frac{k}{t} \, –\infty $\eta f (s) = \displaystyle{\int_{-\infty}^{\infty}e^{-2\pi ist}f (t) DT}$Since $\frac{k}{t}$ is replaced with a continuous variable $s$, the polynomial of the Fourier series is replaced with integral,
As the CE help document says, creating OAL is a very complex task, and the usual approach is to replicate the original OAL code of the same platform and modify it to accommodate the special requirements of the platform. That is to say, for a platform without special requirements, it is sufficient to copy the OAL code of the original same platform. Because of the complexity of OAL in this article, I only explain the common parts.
First, the implementation of ISR
