Was my computer hit by a Trojan horse? It may be a problem with the game server, and Trojan horses are not excluded.
My computer stopped playing games the other day. This is a Trojan horse at work. Finally, I found him. It seems to be called S9 173 commercial. Is to let you always disconnect from the internet, tamper with the home page, and can not be completely deleted, and then recharge the system.
See if there is anything suspicious in the program, then check the plug-in and kill the virus.
Computer browsing the web is very stuck. Is it a Trojan horse? How to fix it? Sometimes it has something to do with your internet speed and browser.
What if the computer crashes? When I opened a web page or video, I suddenly fell down. Analysis reason: 1, browser version problem, or it has been lost or damaged. It is recommended to clear the cache (possibly incompatible, reloaded or replaced). 2. The network speed is not smooth. Tencent computer housekeeper traffic monitoring, check it. If the uploaded traffic is particularly heavy, you should be worried. It may be poisoned, and your information is leaked. 3. Download a flash player. Is the webpage automatically blocked? There will be a prompt under the tab. 4. Check the DNS settings. Tencent Computer Butler Toolbox -DNS Optimization 5. See if IE is poisoned. I suggest you try anti-virus first, safety first, and recommend Tencent computer housekeeper, and really use the ultra-high virus detection rate of 99.8% to get the best test results of AV-C Samsung. Together with Kaspersky, McAfee, BitDefender and Avast, it entered the first camp of global anti-virus software, which once again confirmed its anti-virus ability. And the operation is very simple, the plate is clear, and novices will try it.
The computer always crashes suddenly. Is it poisonous? Not poisoning. This is a system version problem. Just change the GHOST version of the system and install it again. This is a conflict between the two.
Did the mice running around suddenly get infected with Trojan virus? Make sure your mouse is ok! Is that your machine has been hacked! In fact, anti-virus software can't kill poison, which doesn't mean that the machine is not poisonous! You won't kill your master easily! And many small programs that open the back door will be automatically deleted as long as they are executed on your computer and some necessary ports are opened. You don't know! At this time, you can use the stat -ano command to see which ports your machine has opened! If everything like 3389 is turned on, then your machine 100% has been invaded!
The Trojan horse in the computer suddenly shut down and charged the system. After the installation is completed, use Jinshan Trojan horse killing tool to kill again. Try it, I hope it helps you.
The computer won't start. What happened? This is a Trojan horse. The computer won't start.
I usually check like this.
Now I don't know where the specific problem is, and I haven't called the police. Let's consider the simplest problem first.
For example, the memory stick is loose, or the motherboard cannot recognize the memory because of gold finger oxidation. At this time, unplug the memory module, wipe it clean and then plug it in.
This usually solves the problem when you start the computer.
If not, if you have a discrete graphics card, you should also wipe your golden finger after unplugging it. If the motherboard has an integrated vga interface, you can use the motherboard's graphics card interface to plug in the graphics card after determining the problem.
If the memory display card can't solve the problem, don't panic. You can remove the S battery from the motherboard, turn off the power and install it in a few minutes.
Sometimes, due to the change of hardware, the S configuration changes, which may also cause the machine to fail to start.
If all else fails, we should consider the problem of motherboard or cpu.
Cpu problem first check whether the power supply is normal.
There are two situations when the computer can't get into the system when it is turned on: the self-test is only a hardware problem, and the self-test can't get into the desktop, which is a system or driver problem.
1. Self-check can pass, but it cannot enter the desktop. This is an operating system or driver problem:
Why can't the computer enter the desktop normally or the blue screen stops after repeated restarts?
In the case of virus removal, it is usually because the GHOST version or other modified versions of the operating system are installed, and a large number of drivers that are not suitable for your hardware devices are integrated in advance, resulting in the system being unable to correctly identify and load the necessary hardware devices.
This error can be corrected by downloading and installing the original operating system and installing all drivers certified by Microsoft WHQL.
If you don't want to recharge, you can try to turn on F8 to enter the safe mode to uninstall the incompatible drivers of hardware devices (that is, right-click the device in the device manager) > Properties > Presence > Digital Signature Program >: drivers of Microsoft Windows hardware compatible publishers), automatically identify the hardware devices after startup, reinstall the downloaded drivers (WHQL) that have passed the Microsoft digital signature authentication, and then restart the computer again to see if there are any improvements.
Then there is software with duplicate functions in the system, causing conflicts (for example, two or more software killers and firewalls are installed, and advertisements are blocked).
If it is confirmed that it is not a system or software problem, you need to test the hardware in the following order: first, memory is the most likely, then CPU, then hard disk, and finally graphics card. There will be basically no blue screen on the motherboard.
In addition, check whether the machine is overheated due to poor heat dissipation (if it is, it is necessary to install a stronger radiator, repaint the thermal grease and replace the high-power fan).
Check whether the top of the motherboard capacitor is convex (if convex, it must be replaced immediately).
It also depends on whether the output voltage is unstable due to insufficient power supply of the chassis (if so, it must be replaced immediately).
If the power-on self-test fails and no beep is heard, it must be a hardware fault, and the alarm sound of a small horn (buzzer) is needed for preliminary judgment to narrow down the scope of hardware fault. Please refer to your motherboard manual for the specific meaning of power-on alarm sound.
2. If the self-check fails, it must be a hardware failure:
What should I do if I don't hear the "ticking" sound after starting the computer?
After the computer started, the self-test failed. If you don't hear the dripping sound, it must be a hardware failure.
Exclusion inspection requires the following aspects:
1. The system time can't be dBIOSplayed and stored correctly, which is caused by insufficient battery power on the motherboard. This kind of fault can be solved by replacing the new motherboard battery and pressing DEL key to reset the correct system time.
2. Check whether the motherboard capacitor bulges or leaks. If so, please go to a professional computer repair place to replace the motherboard capacitor.
3. Unplug the memory stick, wipe the golden finger with an eraser and plug it back in.
4. Reconnect all hardware and connecting wires firmly to avoid virtual connection.
5. Start the fan once with the chassis open to see if it works normally. If not, it needs to be replaced.
6. Check whether the power supply of the chassis is insufficient, and replace it if there is a replacement power supply at hand.
7. Whether there is a hard disk failure will lead to bad track. Check the BIOS to see if the hard disk can be recognized.
There is no signal on the display, so it is important to check the connection of the display part. The graphics card or monitor itself may be a black screen or a flower screen problem.
9. According to the alarm sound of the small horn (buzzer) of the boot chassis combined with your specific BIOS preliminary judgment, so as to narrow the scope of the problem. Please refer to your motherboard manual for the specific meaning of alarm sound.
10. That's all I can think of for the time being. Other parts are also checked step by step by substitution method or minimum load method.

Not yet. It's poisoning.
