How to solve the problem of IE8 home page modification? Mining Windows 7 potential

  
Windows 7 comes with IE8, like other versions of Windows system, it is also impossible to fundamentally eliminate the problem of IE home page modification. However, we can fully exploit the "potential" of Windows 7 system and enhance the self-protection ability of IE8.

"XX anti-virus software installed, IE home page is modified or Trojan" - this is something Windows users often encounter. For this question, many friends often ask, is there not a complete solution? The author's answer is: Yes, there is no thorough solution. In my opinion, in order to prevent the IE homepage from being tampered with by the Trojan virus, the "only good way" is not to click on an unknown source URL, not to see an unknown source of mail... Today, we will be able to fully exploit the "potential" of Windows7 system. Improve the ability of IE8 to protect itself.

some basic commands can often play a significant role in the protection of network security, the role of the following commands on a few very prominent.

detect network connection

If you suspect that your computer Trojan installed by others, or a virus, but there is no perfect tool for hand detection is not really such a thing happen , you can use the Windows network command to see who is connecting to your computer. The specific command format is: netstat-an This command can see all the IPs that are connected to the local computer. It contains four parts - proto (connection mode), localaddress (local connection address), foreign address (and local connection). Address), state (current port status). With the details of this command, we can fully monitor the connection on the computer to achieve the purpose of controlling the computer.

we at the command prompt type the following: netstat-a show currently open on your computer all the ports, netstat-se a more detailed display of your network information, including TCP, UDP, ICMP, and IP Statistics may have been seen by everyone. Have you ever thought that surpassed the level of understanding of Vista, Windows7 display protocol statistics and current knowledge of TCP /IP network connection system it

House special finishing netstat command usage is as follows (Note:? According to which there is ab order) -

NETSTAT: /Windows7 Vista display protocol statistics and the current TCP /IP network connection. Netstat can be run directly without parameters, as shown:

NETSTAT [-a] [- b] [- e] [- f] [- n] [- o] [- pproto] [- r] [-s] [- t] [interval]

-a Show all connections and listening ports.

-b-executable program according to the display when creating each connection or listening port. In some cases, an executable program is known to host multiple independent components, in which case the sequence of components involved in creating a connection or listening port is displayed. In this case, the name of the executable is at the bottom [], and the component it calls is at the top until it reaches TCP/IP. Note that this option can be time consuming and can fail if you do not have sufficient permissions.

-e Displays Ethernet statistics. This option can be combined with the -s option.

-f show the external address fully qualified domain name (FQDN).

-n display addresses and port numbers in digital form.

-o displays the process ID associated with each connection to have.

-pproto display connected proto specified protocol; proto may be any of the following: TCP, UDP, TCPv6 or UDPv6. If used with the -s option to display statistics for each protocol, proto can be any of the following: IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.

-r Displays the routing table.

-s to display statistics for each protocol. By default, statistics for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6 are displayed; the -p option can be used to specify the default subnet.

-t displays the current connection unloaded state.

interval seconds between re-display the selected statistics, each show was paused. Press CTRL+C to stop redisplaying the statistics.



disabled unknown service Many friends in one day after a system restart will find the computer slows down, this time is likely to be other people through the invasion of your computer you open a special Some kind of service, such as IIS information service. You can use "netstart" to check what services are open in the system. If you find a service that is not open to you, we can disable the service in a targeted manner. The method is to directly enter "netstart" to view the service, and then use "netstopserver" to disable the service.

easily check account

for a long time, very much like a malicious attacker to use cloning methods to control the account on your computer. The method they use is to activate the default account in a system, but this account is not used often, and then use the tool to promote this account to administrator privileges. On the surface, this account is still the same as the original, but this clone The account is the biggest security risk in the system. A malicious attacker can control your computer arbitrarily through this account. To avoid this, you can test your account in a very simple way.

first enter the command line netuser, to see some of what the user on the computer, and then use the "netuser + user name" View this user belongs to any authority, usually in addition to Administrator is the administrators group, the other is not! If you find that a user built into the system belongs to the administrators group, it is almost certain that you have been compromised, and someone else has cloned the account on your computer. Quick use "netuser username /del" to delete the user bar.
