Win 7 system anti-blocking methods and techniques

                                                                                                                                                                                         

Whether it's Win 7, Mac OS, Linux or BSD, the initial loading of the operating system consists of elaborate sequential steps, one after the other. The operating system usually has to set the operating mode of the processor, load the system core, driver and drawing interface, then load the resident program, and finally hand over the usage rights to the user. If this series of "exquisite" is also "fragile", the process is a little mistake, the system can not be loaded, the user will say: "My computer

hanging /crashing /Can't open /die … …” all kinds of arguments, and so on.

There is no possibility of booting up:

1, the driver has a problem.

2. There is a problem with the core program.

3. There is a problem with the disk that stores the OS core program.

4. The user's resident program has a problem.

How to prevent viruses from being executed

So, can you prevent viruses from being blocked by the user's care? We think carefully, what can we do under each link? Here are some common ways to prevent drug clogging.

First, each program must undergo some kind of certification.

In order not to let users not perform dirty things, the operating system manufacturer stipulates that each program you execute must be Check it out ”. However, this closed system is still quite safe - because all software shelves are subject to Apple approval.

Second, each program (as long as it is considered dangerous) users must agree to execute

Windows Vista/7 has a UAC, as long as you judge your program is dangerous Jump out and ask you to "determine", this will make the virus "more difficult to infect you", but the average person has not yet benefited, may be angry to turn off this feature first. But to be fair, it is necessary to prevent poisoning. This is also a necessary evil.

Three, anti-virus software

anti-virus software& quoquo; should be able to prevent executable file viruses, and firewall software & rdquo; should be able to prevent attacks from inside and outside the Internet, and Don't say "I don't mess with dirty things. I don't need to install anti-virus software." - Best of all, you'd better not go online. Some network
worms simply use the so-called "vulnerabilities" to drill directly into your computer
memory, and then your network
is automatically hacked. 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.

Fourth, perform any ”executable” things need to pay more attention

Really, many people mess with the program--and carry it to the virus, this is the most lethal 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 various important files …… The result? The result is & rdquo; light reload, but death is rdquo;, so this may not be "the only principle", but it is indeed the most important principle that the average user should know.

As long as there is a minor link error, the operating system may not load properly - fortunately this situation does not happen often. These are a brief concept of operating system antivirus and I hope to be helpful when you use your computer.
