Why can network viruses be automatically written to local disks?

1. The web page has a backdoor program, which contains a special **, that is, a script, to open the web page, the script program must be opened first, and it will be ** to the disk at the same time, of course, it also has the ability to self-replicate! Some are ActiveX controls.

2. Speaking of principles, it is actually very simple. For example: you are hungry and you bought some food in the store, and you are poisoned after eating it, and you don't know that the food is poisonous!

And antivirus software is a doctor, helping you see a doctor. That's it! If you want to see someone's website, you have to take it down, but you don't know if it's poisonous!

The control keys on the regular ** will not be viral.

You may have installed a control with a virus.

No matter how powerful a Trojan horse is, it is a program to be executed, and if you don't execute it, it will only be a file if it exists.

Nethorse is a special section of **, which mainly exploits Windows vulnerabilities to make the computer browsing the web automatically in the background** and run the program. (Generally speaking, as long as you patch your system or use a separate kernel browser such as Firefox, you don't need to care about Nethorse.)

The vulnerabilities of various application software and systems, most of which are vulnerabilities that overflow and execute arbitrary, are OK.

Open the Browser Tools - Connections - Select Never Make a Dial-up Connection.

You can take a look at Brother Dao's blackboard newspaper, and surf the Internet with a mortal heart...

You should be clearer, whether it is automatic dialing or whether it is connected to the network without dialing when you turn on the phone. If it's autodialing, it's possible that an auto-connection is set up in the dialing software; If you are connected to the network without dialing in at boot, it may be that the route is set.

No, it's a matter of software settings, you can set it up.

It may be that automatic login is set in the settings.

Then go to Start-Accessories-Startup to see if there is a "broadband connection".

Delete if you have one.

Not necessarily, it could be a problem with the settings.

If your home is ADSL dialing, it is possible that such a situation occurs.

4 Records 4 Records 73 This is **. Remember: pie doesn't fall from heaven!

Your question is not comprehensive, huh? Is it that after connecting, it suddenly disconnects and automatically connects when you are surfing the Internet?

You right-click on IE--Properties--Connection, and look at the one selected for the broadband connection.

Then don't use dial-up software, just establish a vnet pppoe connection and see if it works.

Method:"Get started"=>"Settings"=>"Network connection"=>"New Connection Wizard"

Next"=>"Next"=> set up my connection manually"Next"=> requires a username and password for a broadband connection to connect"Next"=> take a name wherever you want"Next"=> Fill in the username and password The two options are optional or optional"Next"=>"Done"

After that, right-click the mouse"Online neighbors"Select Properties, double-click on the connection you just made, select the connection, and try again.

It's basically not a virus, but it's not impossible, just log out and go in.

How do you get online? Dial-up or LAN?

Basically, it's not a problem with the virus, it should be a problem with your cat, the line is aging and unstable, and it's easy to break the line!

It should be poisoned, if it is not poisoned, please check whether the power supply voltage is stable. There is software detection.

It should be a virus.

Go online and find an antivirus software to kill it.

You can go to Kaspersky for a 30-day free trial.

I pressed the broadband, and the Internet was poisoned...

The so-called hardware routers used in Internet cafes are actually very bad.

The reason for the disconnection is difficult to judge, and the automatic connection is just a normal function of those routers.

It is recommended to replace the soft route, which may cause disconnection due to P2P software, worms, and ARP attacks

IPTV software, etc., etc., etc.

It is also necessary to judge that the ISP** business has a normal network.

If you just don't understand and want to ask, then the above answers won't help you in any way.

Stable lines? Viruses are also possible.

Yes, it is possible for the first two and there can also be problems with the router.

All of the above reasons are possible, and device matching issues are also important.

The most thorough way is to do the system.

Call Netcom's maintenance personnel to help with repairs, this may be a problem with the corridor switch, which can only let their maintenance personnel come to help check, and your computer should have nothing to do with it.

Do you want to try network repair!! Maybe it's not the legend who has been poisoned...
