Defense Techniques for mail viruses

In the Daily network application, the email has become our commonly used tool, its sending speed and the loading attachment function has provided the very great convenience to us. But because of the convenience of e-mail, it has become a form of transmission of the virus. A virus message is very harmful to Internet users, but the harm of virus mail is not preventable. As long as we understand some common sense, master the prevention of 10 law, virus mail will no longer "useful"!

First, install anti-virus software

To deal with virus mail, simple by hand to prevent is not realistic, is also unscientific. Therefore, first must install an anti-virus software. Now basically all of the mainstream anti-virus software provides the message monitoring function, when receiving, sending mail, will automatically check the content of the monitoring message contains viruses, for the virus mail will be automatically processed according to the settings, so as to avoid the virus running and spreading.

Second, do a good job upgrading

The upgrade includes two parts, one is the antivirus software upgrade, the other is the system upgrade. For anti-virus software upgrades, I believe that its importance is self-evident, only the use of the latest virus library to maximize the protection against viruses, especially to respond to new viruses, all kinds of virus variants. It is also important to upgrade the system. Because a lot of virus is because the system has a loophole to release, if we can lay a good patch in advance, to avoid the existence of system loopholes, so the virus naturally does not attack.

Third, identify the subject of the message

Because virus mail is usually sent automatically or sent in bulk, its theme will show certain characteristics. For example, "old classmate, long time no See", "Please check it", the theme of the keyword showed a high confusion, tempting users to view the message.

Check email attachments

If the message contains an attachment, and the body of the message also displays "My photos in the attachment, check it out!" And so on, then you must be careful not to listen to what it said, see the attachment icon is a picture file, text file is considered safe. To know the full name of such a file is often 1.jpg.exe, 1.txt.exe, so it is best to go to the Folder Options window, set the display extension, confirm that there is no exe suffix to open. In addition to disguise as a picture file virus mail, we can first preview, if you can preview its picture content, then open the recruit may be a lot of decline.

V. Disable Address Book

For the convenience of contact, many people are accustomed to add contacts to the Address book, so the direct choice when sending the message can be. But know that if you are infected with a virus, then the virus will automatically send all the contacts in the Address Book a virus mail, so that the cycle caused by the great harm. So we can put the contact information in a file file, write the message directly from the text file copy. While this can be a bit inconvenient, it is necessary for some business users or for businesses that use e-mail to compare frequencies.

VI. Disable Stationery templates

Many users will choose some stationery templates from a beautiful point of view, but there is a price for beauty. Because these templates often invoke script files to achieve certain effects, these script files are very susceptible to viruses such as js/vbs, and if a user uses a virus-infected stationery, it is a virus message.

Vii. handling of spam correctly

Mail virus messages are spam messages, and users often choose to delete them directly after discovering them. But after the direct deletion, the mail does not disappear, but is saved to the Trash box or the spam mail, in which we people must clear them from the waste box, then right click the Trash box, chooses empties the Trash box operation, thus can completely remove.

Eight, enable automatic filtering

Whether it is based on web hosting or using transceiver tools such as client Foxmail, automatic mail filtering is generally provided. In this case, we need to enable it, not only to prevent spam, but also to filter out some virus mail. In addition, some senders from unfamiliar addresses should be added to the blacklist to avoid the occurrence of messages with the same address.

Nine, use plain text format view

Because the message generally has HTML and txt two ways to view, using HTML to view the message although you can see the original message, but because the HTML file can load JS code, easy to create damage, compared to TXT file is not the problem. We can set the default view of the message to TXT format, wait for a general understanding of the message body content, found no exception and then switch to HTML browsing.

Ten, study the virus prevention knowledge seriously

Because the virus information changes very quickly, if we can not strengthen this knowledge of the absorption, it is very easy to be confused by the virus. Therefore, as far as possible to understand a variety of virus information, master its characteristics, to know the known, you can do win.
