The solution is to display the file extension: My computer /tools /folder options /view /hide the extension of the known file type, cancel this item. At the same time, friends who don't know the extension should learn the lesson: There is no free lunch and A film in the world. Please look at the beautiful yellow website. Don't think that there will be a good thing in the sky. Before running an unknown file, you must first check the virus and check its real extension.
One patch immediately after reinstalling the system
The first thing after reinstalling the system is to patch. The probability of surfing the Internet without poisoning is not as bad as jumping into the pit.
Two don't search for software (songs, movies)
Now many rogue download stations, they don't even provide any good software downloads, just get better Baidu rankings by various means, when users click to download In fact, it is downloading Trojans! There are some normal download stations that sell advertisements to Trojans. The advertisement looks like "Download button", it is very likely that you have accidentally clicked on it.
The solution is to some websites with good reputation. For example, we have compiled the necessary software for Windows installation, all support win7, Vista system
Three do not insert U disk (unknown) (MP3/camera card /Mobile hard disk)
The poisoned USB flash drive may be poisoned as long as it is inserted into the computer without any operation. Because Windows has a metamorphosis function called autoplay, after the USB flash drive is inserted, Windows actively executes the virus on the USB flash drive.
The solution is to disable the automatic playback of the USB flash drive. Method: Vista Optimizer, WIndows 7 Optimizer, Rubik's Cube - System Optimization - Multimedia - Tick "Allow the automatic operation of USB devices"
Be careful with Windows There is another metamorphosis function. If the USB flash drive can be played automatically, the default operation of modifying the double click is to play automatically (even if there is no security problem, the product design is very stupid). That is to say, although the U disk does not run automatically, but you double-click the drive letter of the USB flash drive to open the USB flash drive, which actually triggers the virus in the USB flash drive.
When you know that the U disk is toxic but you don't have anti-virus software but you have to use the files, right click on the drive letter of the USB flash drive and select “ Resource Manager” in the menu. Experiments prove that this operation file will not trigger the virus. .
Four Don't be spoofed by file name to actively execute virus files
Windows has a setting that hides file extensions, and many viruses hide themselves through this setting. For example: a virus name is: & ldquo; Yan Zhaomen actually has her .jpg.exe & rdquo;, at the same time change the icon into a picture, to induce users to click.
5 Do not open the attachments of emails directly and the files sent by QQ
QQ strangers will directly delete your attachments, nothing to be curious. Mail sent by acquaintances should be saved locally. If there is anti-virus software, check it out. No anti-virus software to view the extension, executable attachments (extension: exe /com /vbs /chm /htm /bat /doc, etc.) must be cautious; secure attachments (extension: txt /jpg /Gif) can be opened with confidence.
