Yesterday, while reading the newspaper, I came across an article saying that a supervisor at 104 Job Bank had been monitoring employees’ instant messages. I won’t comment on that, since it’s an adult matter. From the company’s point of view, of course they want to take measures to prevent employees from leaking information, and the company had told employees that instant messaging software would be monitored. But from the employee’s point of view, it must be really annoying, since nobody likes being watched. Oops, I’ve drifted off topic a bit~~ Anyway, this post is going to teach you to use two programs: MSNShell and SimpLite-Yahoo. ...

Have you ever wanted to visit a website, only to find it blocked? (Usually it’s adult videos…) Or maybe you mistyped something while logging in and got your IP blocked? When that happens, you can use the “proxy IP” (Proxy) introduced in this post. A proxy IP (Proxy) is really a web proxy, and it can hide your identity while you browse. It sounds like magic, but the principle is not hard to understand. You first connect to the proxy IP (Proxy) server, and then connect to the website from there. In other words, you go online through a proxy server, so the IP address left behind is not your own. But please don’t use this for bad things, because most proxy companies keep user data. If you do something illegal, it can still be traced XD ...

Most people have heard of packers, such as UPX, but do you know how they work? Have you ever tried writing one? Is it hard? Actually, the principle is quite simple. Let me, Feng-lai, explain it for you~ The first step in writing a packer is to get the binary file of the program you want to pack. Everyone knows that every file on a computer is a binary file, right? A binary file is made up entirely of 0s and 1s. So what do you do with it once you have it? Encrypt it, of course. The simplest encryption method would be to invert every bit: each 0 becomes a 1 and each 1 becomes a 0. But you can’t just run the encrypted file directly, so the second part comes next. ...

Today I am introducing a program called HxD. It lets you view a file’s hexadecimal bytes. Although HxD is free, it is no less capable than professional-grade editors. HxD not only supports basic hex viewing but can also directly control memory. HxD also has an export feature: you can export modified files directly as source files for languages such as VB or C++. Personally, I think anyone who often works with computers should keep it on a USB drive, just in case. ...

While browsing the web today, I was surprised to find that I couldn’t connect to Microsoft’s website. It reminded me of the disaster when my computer broke down last time…. and sure enough, it really happened again! Last time, for some unknown reason, my computer couldn’t connect to any Microsoft-related sites, nor could it open antivirus software websites, and the virus definitions wouldn’t update either. Back then I just reinstalled everything directly, since the computer had been used for quite a while. But this time the computer was barely bought and it’s already acting up @@ After all that rambling, the reason I’m recommending FixDwndp today is this: I personally suggest that readers of this article go check right away whether your computer has the following symptoms: You can't get into the Microsoft official website You can't get into the websites of major antivirus software Automatic update notifications haven't popped up for a long time Antivirus software can't update its virus definitions...

Gmail users have probably been getting a lot of emails signed “Me” lately, right? But I never sent an email to myself, so why am I receiving them? Here is a reminder: if you receive this kind of email, I suggest you delete it right away. These emails usually don’t contain any ads. They just have one sentence asking you to click a link. I don’t know what happens after you click it!! ...

Some viruses use the registry to damage computers. Basically, I’m only posting one example here; the registry has many other places where things can be hidden, so if you don’t know much about computers, don’t try to change other places. At best nothing happens, at worst the computer is ruined. Following the steps below is safe. “Start” “Run”, type “regedit” HKEY_CLASSES_ROOT\exefile\shell\open\command HKEY_CLASSES_ROOT –> exefile –> shell –> open –> command Then check the “(Default)” value. If it is “%1” %* it is normal. If it isn’t, your computer has been infected. Double-click it and change it to “%1” %* Also, pay attention to other places!!
