My friend has a virus W32.Jeefo today. The virus can increase the file space, and the virus is highly contagious and involves a wide area.

Some may first think of anti-virus software, such as rising, but we have not considered that the anti-virus software function is to directly clear viruses or
Isolation, but directly clearing some files may damage, and a friend's personal server and a program written for one month are infected with the virus, so
Do not do that. You can first find a specific killer, or find the virus information and then manually disinfect the virus. With this idea, I will start.
Anti-virus measures.

Opened the rising Official Website
Www.ruising.com.cn. Should be a http://www.rising.com.cn /)
I searched for information about the virus database and did not find any information about the virus. Depressed, how to connect
Why can't rising kill? I have not tried any other anti-virus software. Go to Baidu to search for the virus. After some knowledge, I know the name of the virus is "Jie ".
Jeff is a virus in the memory. If the virus runs, it will be copied to the windows root directory and named "svchost.
Exe %WinDir%svchost.exe, and then add a key value to the Registry.
[HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunServices] "PowerManager" = "%windir#svchost.exe"


Each time the copy of the virus restarts, it will run. The virus searches for the win32 PE with the exe extension in the logical partition of the infected computer and can be executed.
File. The infected file size is increased by 36352 bytes.
I have some knowledge about the introduction of the virus. This introduction was developed by Kaspersky, but I didn't find the exclusive tool, which is depressing.
It seems that I can only do it manually. I asked some people based on the virus and posted a post on the Firefox Technology Forum. Lin Ge gave me some help tools.

Delete and restart
I forgot to mention it. Remember to make A win32 patch after it is completed.
This time it took a lot of effort to get this virus, because I used to get used to it.
I want to learn more about the registry in the future, because many viruses need to be killed in the registry, anti-virus software.
Although the virus can be killed, it may cause some losses. If the virus is manually killed, it will be fine.
