Eliminate misunderstanding identify the system files that are easily mistaken for viruses _ Web surfing

With the popularization of computer and the development of information technology, the word "computer virus" is no longer unfamiliar to everyone, and nowadays computer viruses are emerging, even the vast majority of users have almost to "talk about poison color change" degree. Jiangmin's technical engineers have found that many users are not so knowledgeable about the files under the operating system that they have all sorts of suspicions.

The following are files that users often suspect are viruses:

First, thumb.db documents

The reason why the thumb.db file is mistaken for a virus by the user should be three points:

1, the file in some operating systems with pictures in the folder exists;

2, even if you delete this file, the next time you open the folder will still be generated;

3, the file may be increasing.

In fact, thumb.db files are available in Windows Me or newer versions of Windows, which is a cache of Windows (or a buffer file) that makes it easier for users to preview pictures, and the more pictures you have, the more likely this file will be, which is normal. This file is not generated when you select "Do not cache thumbnails" In Folder Options under Windows XP systems.

Second, Mfm1992 file or "Mfm1992.AVB.AVB.AVB.AVB (suffix is infinite AVB)"

The main reason Mfm1992 file users are mistaken for viruses is that this file may be generated in any folder and may be regenerated after deletion.

The Mfm1992 file is a file caused by an error in the intelligent ABC Thesaurus. Because the intelligent ABC Input method's thesaurus capacity is limited, when exceeds this capacity, will produce this file. The directory in which the current program runs, and the file is generated in that directory. The size of this file is typically 43KB. This is an intelligent ABC4.0 with a bug,win2000 and a smart ABC5.0 in me that has fixed this error.

If you want this file to stop appearing on your computer, there are two ways to do so:

1.4.0 Intelligent ABC can be upgraded to a higher version.

2. You can delete the *.rem file in the Windows\System directory and restart the computer.

Third, word temporary files

When a user opens a Word document, a document appears in the same directory with a Qu   Portuguese joyriding  regretful the waved 觥 $ "symbol. Its icon is the same as the icon in the Word document, but the" gray "color (that is, has hidden attributes). Many users feel suspicious and think it is the result of a virus.

In fact, this is a normal phenomenon, this file is generated by word, can be understood to be a buffer file, its role is to maximize the save for unexpected reasons (such as sudden crash, etc.) caused by the user to modify or establish the Word document is not saved when the loss. In fact, this file will automatically disappear after the Word document is closed, so users don't have to worry.

Iv. jdbgmgr.exe Documents

Unlike any of the above files, the file is not a file that was generated when an error occurred, nor is it a temporary file, and is a normal system file. The user is not aware of it because it exists in the system directory. But many users think of it as a virus because a deceptive e-mail message is distributed around the Internet. The email, disguised as a virus-prevention report, warns users of the message that the "jdbgmgr.exe" file is a virus that can damage the entire computer system after two weeks of infection with the PC. The lie is being distributed around many PC users who believe they have been infected, in the hope of helping other victims to clear the virus.

In fact, the "jdbgmgr.exe" file is a Java Debug manager and is an integral part of the Java software installed in all Windows systems. Once the file has been deleted, it may cause some javaapplets and JavaScript to stop working.
