The author's computer recently in the use of a strange phenomenon, double-click D cannot open directly (other letter is normal), always pop-up prompts "Can't find Pagefile.pif, specify location", so each time only through the right button "open" menu to open, and carefully look at the right button menu found that there is a " AutoPlay "item.
Failure Analysis: The Internet search for a while, according to the data can be found to determine the author is in the process of browsing the Web page or transfer files in the course of the Trojan virus caused. So I opened antivirus software NOD32 (has been upgraded to the latest version) to the hard drive a deep antivirus, strange is a virus also did not find.
Because I do a virus scan every day, the virus is estimated to have been killed by himself. Based on the information that was found, most likely the virus in D disk residue a file Autorun.inf (some viruses will often use this file in the computer automatically run), but it itself does not have virus characteristics, anti-virus software anti-virus when it can not completely clean, but it remains after the computer has brought Sequela- Causes the hard drive to not open properly.
Troubleshooting: Because Autorun.inf is a hidden file, when the author of the folder Options selected as "Show All Files and folders" also failed to find this file in D disk figure, so here I will skillfully use the most commonly used winrar to clean.
First run the WinRAR software, in the interface click on the right of the Address bar Drop-down list, the path to the D-packing directory, this time to find D disk hidden file "Autorun.inf" finally appeared, needless to say, in the file point right click to select "Delete File" (as shown). Now try it, D plate can be opened normally. But not yet, don't forget to clean up the registry entries, open the registry, look for "pagefile.pif" content, find a shell key, its subordinate key value is "d:pagefile.pif", delete this key, the virus residue cleaned up.
Figure Autorun.inf finally appeared, delete it!
