How should we respond to the global outbreak of computer viruses?
According to reports, on May 12, a global Bitcoin virus madly attacked public and commercial systems! More than 40 hospitals across the UK have been attacked by widespread cyber hackers, plunging the National Health Service (NHS) into chaos. Many university campus networks in China have also collectively collapsed. Nearly 74 countries around the world have been seriously attacked!
In addition to paying huge amounts of ransom, the extorted targets also face other potential threats. For hospitals, first, the patient's diagnosis history and medication history will be encrypted, making it difficult to obtain. Second, it will affect the operation of the entire hospital, making it difficult to operate certain devices that rely on computers to control, including operating room reservations and operations. These threats are undoubtedly very detrimental to ensuring patient safety. As for other enterprises, their operations will also be negatively affected, which is likely to lead to unnecessary economic losses.
"Ransomware" spreads rapidly. Once infected, users will be trapped in a dilemma with nowhere to escape. Whether to pay the ransom is a dilemma, so "prevention" is the only and best way. Network experts Some suggestions are put forward to avoid being affected by ransomware:
Tips 1. Delete suspicious emails received, especially those containing links or attachments
2. Some Microsoft Office files. Users will be asked to launch "macro" to view its content, so be wary of such email attachments
3. Back up files on your computer regularly
4. Make sure to update your computer. Intrusion prevention security software
5. Keep your operating system and other software updated.
6. Once infected, immediately isolate the infected computer from the network and external storage devices. Do not open any files before removing the malware.
7. Paying ransom is not recommended.
8. To download software, use the official software download platform for mobile phones and computers.
How should we prevent computer viruses
1. Establish good security habits and do not open suspicious emails and suspicious websites.
2. Do not randomly accept files transmitted through chat tools and open website links sent over.
3. When using removable media, it is best to use the right mouse button to open it and scan it first if necessary.
4. Nowadays, there are many viruses that exploit system vulnerabilities to spread, so it is also critical to fully patch the system.
5. Install professional anti-virus software, upgrade to the latest version, and enable real-time monitoring.
The devil of the information society: What is a computer virus? How do people deal with computer viruses?
It is to write a program to obtain the specified file and send it to the hacker's computer or hide it in the computer. You can get things secretly on the Internet, and if you change the layer sequence randomly, the computer will no longer work. Computer viruses are very annoying. I have been hit by them a few times. You have to reinstall the system. If there is a new virus, upload it to a security company and they will crack it. View original post gt;gt;

How to prevent computer virus invasion
I have summarized some knowledge in this area, It's very useful. I tried it, and basically very few viruses invaded my computer. If you don't believe me, you will know after trying it. Fang Zhangxiao, I hope you will read it patiently: Common ways of intruding personal computers when talking about personal security when surfing the Internet. , let’s first categorize the problems you may encounter. The intrusion methods we encountered probably include the following: (1) Passwords stolen by others; (2) The system is attacked by _blankgt; Trojan horse; (3) Attacked by malicious java scrpit program when browsing the web; (4) QQ is attacked or information is leaked; (5) Virus infection; (6) System vulnerabilities allow others to attack you. (7) _blankgt; malicious attacks by hackers. Let’s take a look at what methods can be used to prevent attacks more effectively. Check local ***shared resources Delete ***share Delete ipc$ Empty connection Account and password security principles Close own port 139 Close port 445 Close port 3389 Close 4899 Prevention Introduction to common ports How to view the ports opened on this machine and filter them Disable services Local policy Local security policy User rights assignment policy Terminal service configuration User and group policy Prevent RPC vulnerabilities Do it yourself DIY Security options tool introduction in local policy Avoid being attacked by viruses such as malicious code Trojans 1. Check the operation of local shared resources CMD enter net share. If you see any abnormal *** sharing, you should close it. But sometimes when you turn off *** sharing and it appears again the next time you turn on the computer, then you should consider whether your machine has been controlled by a hacker or is infected with a virus. 2. Delete *** share (enter one at a time) net share admin$ /delete net share c$ /delete net share d$ /delete (if there are e, f,... you can continue to delete) 3. Delete ipc$ empty Connect and enter regedit in the runtime, and in _blankgt; find in the registry that the numerical data of the numerical name RestrictAnonymous in the HKEY-LOCAL_MACHINESYSTEMCurrentControSetControlLSA item is changed from 0 to 1. 4. Close your own port 139. IPC and RPC vulnerabilities exist here.
The method to close port 139 is to select the "Internet Protocol (TCP/IP)" attribute in "Local Area Connection" in "Network and Dial-up Connections", enter "Advanced TCP/IP Settings" and "WinS Settings" and there is an item "Disable TCP/IP". IP NETBIOS", check the box to close port 139. 5. To prevent rpc vulnerabilities, open the management tool - Services - find the RPC (Remote Procedure Call (RPC) Locator) service - set the first failure, second failure, and subsequent failures in fault recovery to no operation. XP SP2 and 2000 pro sp4 do not have this vulnerability. 6. Close port 445. Modify the registry and add a key value HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NetBT\Parameters. Create an SMBDeviceEnabled in the right window and set the key value to 0 for the REG_DWORD type. This is OK. 7. Turn off 3389 XP: Right-click on My Computer and select Properties -> Remote, and uncheck the two options boxes of Remote Assistance and Remote Desktop. Win2000server Start--gt; Program--gt; Management Tools--gt; Find the Terminal Services service item in Services, select the property option to change the startup type to manual, and stop the service. (This method is also applicable to XP)
