Different Responses of Kv and rising to the same virus

Source: Internet

Today, a friend bought a second-hand computer and asked me to check it out.

Although kv2004 is installed in the machine, the machine may not trust kv2004 and may have Trojans or other information. We decided to use rising to scan for viruses online. By the way, we made a simple comparison between kv2004 and rising. It's really no surprise to know.

The original kv2004 in the machine can be upgraded to version Z. First, update the virus database to the latest version.

Then, the system was fully scanned and no viruses were found.

Using rising online for free drug detection, we found one:

Fortunately, I am very alert ....

Because the virus file is in C:/Windows, kv2004 is used to scan C:/Windows. The result is as follows.

Information about the virus in the rising virus database:

Http://it.rising.com.cn/antivirus/virusdataasp/viruslist.asp? Id = 65920

Virus classification PE virus name in Windows trojandownloader. win32.dyfuca. cv. dll
Virus length by name
Dependent system communication channels
Behavior Type: Trojans in Windows
Virus attack, rising version, 16.40

An automatic download tool.

First, pack the virus file with WinRAR, and then use Rising Antivirus assistant's "delete at next startup" to kill it.

Then, the virus file compressed package is sent to the mailbox for sample storage, and is unexpectedly scanned and killed by anti-virus software on the Netease email server.

It is estimated that you have to set a password for the compressed package to defraud the email service for anti-virus software scanning. Get it back when you are free...

PS:

To be honest, the kv2004 I met when I was helping my friend repair the computer, and rising could detect more than this virus.

I met one more time before the holiday, in the security software discussion board of the rising community, a netizen mentioned in a good post about kv2004 and rising (just roughly scanning the existing posts of this version from the first page to the last page) again, I don't seem to have found that post). A netizen said that he has never seen a virus that kV cannot be killed (to the general idea). Today, when this happens, he saved the relevant picture, paste it to the netizen.

Of course, you cannot simply comment on anti-virus software from the performance of virus detection...

I believe everyone will have their own ideas, so I don't want to draw any conclusions on this simple comparison...
