Solution to a series of problems after the completion of Anti-Virus

Nowadays, computer viruses are changing with each passing day, which is a helpless choice for every computer user. After a long period of detection and removal, the virus is gone, and the troubles are also followed. Either a file loss error or a file association error occurs ...... The above system faults can be collectively referred to as "anti-virus sequelae ". So how can we fix the sequelae of antivirus?

1. File not found

After the anti-virus is completed, enter the system and prompt that a file is lost. In this case, different measures should be taken based on different situations.

1. the first case is that the virus program adds a key value to the self-starting entry of the registry, while the virus program is cleared during the antivirus process, but the relevant content in the registry is not deleted, after the machine is started, the system prompts that the file is lost. For example, the virus adds "run" = "RAVMOND.exe" into [HKEY_CURRENT _ USERSoftwareMicrosoftWindows NTCurrentVersionWindows] in the registry ". For this type of false file loss, we only need to delete the key values in the Registry's auto-start item. Note the following key values:

(1) [HKEY_CURRENT_USER

SoftwareMicrosoft Windows NTCurrentVersionWindows]. The Load key under it is the automatically loaded project command line. The default key value should be null.

(2) [HKEY_LOCAL_MACHINE

SoftwareMicrosoftWindows NTCurrentVersionWinlogon], the shell key under it is the system "shell", and its default key value should be "C: Windowsexplorer.exe" (excluding quotation marks ).

(3) [HKEY_LOCAL_MACHINE

SoftwareMicrosoft WindowsCurrentVersionRun], each key value corresponds to a self-starting program. If a file is not found in the pop-up immediately after entering the system, but the system is running normally, this situation occurs, if the file name is lost as prompted, the residual Registry Key of the virus can be found here and deleted.

In addition, pay attention to the auto-start items in the Start menu and [HKEY _

CURRENT_USERSoftwareMicrosoft WindowsCurrentVersionRun] registry branch.

2. The second case is that the virus destroys the system file, and the antivirus program deletes the system file that has been infected with the virus, resulting in the loss of the file prompted at startup. In this case, we only need to follow the prompts to write down the lost file name, and then copy the same name file from other operating systems to overwrite the original file directory. It can also be extracted directly from the installation disc. If you do not know which directory the lost file is located or there are too many lost files, you can enter and execute the "Sfc/scannow" command in the "run" dialog box, after you press enter, the system starts the "Windows File Protection" program, prompts you to insert a Windows system CD, and then starts scanning. After scanning is complete, all the lost or damaged system files will be intact. If the system cannot be started to the desktop, you need to use the installation disc to start to the fault recovery console, use the Expand command to release the file.
