Execution is the most dangerous thing
The problem is, Windows by default hides file extensions recognize it, so, to be honest, you do not know in the end you did what.
it does not matter, as long as you imagine: ── What you definitely have to perform when you double-click the left mouse button on an icon.
when ── execute what you have to remember: this is our "absolute users to pay attention to the" RedFlag "the signal." If there is something you must be alert to, besides the "someone asks you for a password", the other thing is this.
So, you must remember:
"Be careful when performing Gesha thing."
It's that simple.
because many viruses can attach to the executable file inside, you "on the implementation of a poisoned." Not only that, but before the poisoned computers are cleaned, they will continue to infect the files on the computer, send out virus letters, or infect other files on the server... and the virus will modify the system settings to allow users The clean-up work of "even if it is found to be wrong" has become difficult - sometimes almost impossible.
So, sometimes, the computer poisoning not have to reinstall the whole, since all executable files are infected and can not be recovered.
Internet is the "gates of hell"
but I'm afraid there is a real thing ── hard to prevent that page!
even when you go to use any browser A web page, to be honest... the door to hell is open. Because web pages allow you to do a lot of things, perform a lot of functions -- and mostly auto and you don't know. Normal web course not the whole you, or you poisoning ...... but, in fact, not normal web has a lot of miles!
In fact, you should know that the browser itself is a "performer" It is itself a tool designed to "use a variety of functions." Not only that, but the operating system still has the so-called "compatibility" problem, but the browser itself is designed to be called "cross-platform". It is best that all browsers have the same capabilities so that web developers can write A feature -- that can be used by all users around the world -- gosh! Reality of the world is no different. But it also allows web virus writers have a chance ...... there any way to make these virus writers and more economical thing? Of course, is to write a cross-platform universal virus it!
page class There are many forms of viruses, some of which use the so-called "narration" (t) to constantly bounce annoying windows, some will secretly put the virus on your computer, and some will directly perform some damn actions... and honestly This kind of problem is more troublesome than executable file poisoning because the user simply can't know.
Therefore, anti-virus software (or so-called InternetSecurity) in this case exceptionally important.
method to prevent the virus being executed
so, users can rely on careful attempts to prevent the virus fled? We think systematically, under every aspect, we What can be done under some common "approach attempts to prevent poison" list:
each program to go through some kind of certification
in order to prevent users to perform should not be executed Dirty things, so the operating system vendor stipulates that "every program you perform must be checked." Oh, do you think it's funny? No, the iPhone is like this - although it doesn't mean to be anti-virus, but the closed system is quite safe - because all software is approved.
each program (as long as there is the risk of being identified) have agreed to implement user
WindowsVista /Windows7 under there UAC, as long as you determine program would incite dangerous to You "ok", this will make the virus "more difficult to infect you", but the average person has not suffered from it, may be angry to turn off this function first. But to be fair, it is necessary to prevent poisoning. This is also a necessary evil.
installed antivirus software antivirus software "should" be attempts to prevent the executable file viruses, and firewall software "should" be attempts to prevent attacks from the Internet inside and outside, and you do not say "I I don't have to install anti-virus software without messing up things." Best of all, you better not go online. Some network worms simply use the so-called "vulnerabilities" to drill directly into the memory of your computer, and then your network connection is automatically paralyzed. Even if you don't do anything, you will have the possibility of poisoning. So be sure to use anti-virus software - whether it's a free version or a paid version.
perform any "executable" things, you are much attention
Indeed, many people perform random program ── and passing execution to the virus, which is lethal biggest problem ── Why? Because, this is "you do it yourself", so the virus can definitely do whatever it wants, it will replace the system registration file, stealth into the depths of the computer hard drive, infect all kinds of important files... the result The result is "light reloading, heavy death", so this is not necessarily the "single principle", but it is indeed the most important principle that the average user should know.
