How to automatically restart the Internet?
Reason explanation and treatment method:
Once the Internet is automatically reset, first of all to troubleshoot whether it is a hardware problem, you can try to replace the network card, or to detect whether the computer
There is a phenomenon of device conflicts happening. If the system has a countdown, the time to automatically restart after arrival, the machine may be a virus or
There is a vulnerability that was caused by the attack. This is the case, for example, of machines infected with Shockwave, shock waves, or sniper viruses.
Take this virus as an example, we will explain:
Shockwave virus (W32. Blaster.Worm) The worm exploits the vulnerability of RPC's DCOM interface to the remote system
The port on which the RPC system service is listening sends the attack code to achieve the purpose of propagation. Infected system to. IRC is more often
Chat tool, this time it became the object and accomplice of the virus attack. The worm will use IRC chat tools on the infected machine
Leave the back door, wait for the remote controller's command, or through IRC for virus upgrades and other operations.
Shock Wave (Worm.sasser) virus to use Windows Platform LSASS vulnerability spread, the system will open after the Recruit 128
Threads to attack other online users, can cause the machine to run slowly, network congestion, and let the system keep the countdown to restart.
The degree of damage is likely to exceed the "shock wave" inexplicably crash or restart the computer;
• The Task Manager has a process called "Avserve.exe", "Avserve2.exe" or "Skynetave.exe" running;
• Create a virus file named Avserve.exe, Avserve2.exe, Skynetave.exe under the system directory;
• Most system speed is extremely slow, CPU occupies 100%.
The sniper virus is a virus that proactively attacks a serious vulnerability in Microsoft's system and is named Zotob (WORM.ZOTOB.A). Zotob
The virus exploits the active transmission, its harm degree and the concussion wave similar, once is attacked, the user's computer will appear unceasingly restarts, the system
Instability and other circumstances. Zotob exploits Microsoft vulnerability, Windows Plug and Play Service Vulnerability (ms05-039), attacks TCP end
Port 445, similar to the shockwave and shock wave method, the attack code sends the vulnerability code to the target system's 445 port, causing the target system
Buffer overflow, run virus code at the same time, propagate. When the virus attacks the target system, it may cause the system to reboot continuously, with the shock wave,
The shock wave is similar during the attack.
Expert suggestion: After installing the system, move to install the genuine anti-virus software and upgrade the virus database in time. When Microsoft announces a system
After the vulnerability, the first time to play the system patch. You can also use Windows Update in Windows to implement this feature. If you use
Windows XP SP2, it is recommended to open a firewall with Windows on without installing a third-party firewall.
