1. If you can't kill it completely, back up your data and then reload the system. Otherwise, it's really troublesome to delay your work
2. This kind of virus is mentioned by Tencent security
you can download and install a Tencent Royal point
after opening it, you can directly check and kill this kind of computer virus by using the virus checking and killing function in it

3. This depends on the file name, there is no way to accurately see whether it is a virus, it is best to use security software to detect, you can install a computer housekeeper, and then choose to kill the virus, and delete the virus from the computer
4. You can first use 360 for antivirus, if it is a stubborn virus, it is recommended that you re install the system
5. 1, is too laggy to see the flow chart, find the problem
when the page is very stuck, sometimes it doesn't respond to
2 or top dynamically view the process
I immediately log on to the server with problems, and the remote operation is very stuck. The flow of the network card is very large. Through top, an abnormal process is found to occupy a relatively high resource. If you don't look at the name carefully, you really think it's a web service process
4. End the abnormal process and continue to trace
kill - 9 nginx1
RM - F / etc / nginx1
after killing the process, the traffic will immediately come down, and the remote will not be stuck. Do we think the processing is completed by deleting the program file and killing the abnormal process? It's certainly not that simple. This is a Trojan horse, and it will generate program files by itself (as expected, before I know it, it will be generated again later). We have to continue to trace it.

6. 1. The most simple and effective way is to reload
2. To check, find the virus file and delete it; After poisoning, the CPU and memory utilization rate of general machine will be relatively high, and the machine will contract out to other abnormal situations. The troubleshooting method is briefly introced as follows:
# top command finds the process with the highest CPU utilization rate, and the general virus file naming is messy
# PS aux can be used to find the location of the virus file
# RM - f command to delete the virus file
# check the plan task, and Whether there are other files in the boot item and virus file directory can be deleted, etc.
3. Since there are latent viruses even if the virus file is deleted, it is best to back up the data of the machine and then reload it.

7. You can find a lot of anti-virus software under Linux. In fact, there are not many linux viruses. The main reason is that some windows virus packages exist in the Linux file system and do not attack. However, as a file server, Linux can still spread the virus to other windows computers.
8. Feitian integrity is good, the address is in the Datang Telecom Institute opposite to Beihang, not far from the metro station, so the traffic is quite convenient. The second floor of Keyuan hotel in Datang Telecom is the common staff canteen in the hospital. Breakfast, lunch and dinner are provided, and the variety is also rich
the internal salary is confidential and we don't know each other, but it certainly doesn't follow the low level of the same instry. The specific value depends on personal ability. The working environment has nothing to say, I give a few details: the detection department allows music playing ring working hours in order to adjust monotonous work; The bathroom provides warm water for many years, and there are many microwave ovens in the corridor for hot lunch; Employees will receive cake coupons and a personalized gift (such as a USB flash drive with your name) on their birthday, and get everyone's blessing in the internal forum. In a word, it's quite humane and respect for talents
for the position of technical support, you really need the programming ability of C / C + +, if you know the encryption algorithm better. Because the technical support here is not only to contact customers in business, but also to assist users in the secondary development based on the company's procts, so the technical ability is still required
I hope it can help you.
