W32.Fiala.Worm virus crashes Windows' automatic update feature

More than 35,300 computers in Vietnam have completely disabled Windows Automatic Updates, unable to automatically update patches for Microsoft Windows operating systems. According to Bkis analysis, the cause of this situation is caused by the variant of the W32.Fiala.Worm virus originating from China.

W32.Fiala.Worm is a virus that takes advantage of Windows vulnerabilities to spread, so when it first enters the computer, its first goal is to find ways to prevent users from updating patches to Windows. . To do this, W32.Fiala.Worm overwrites the malicious code on file wuauclt.exe - the most important executable file of Windows Automatic Updates system, turning this file into a virus file and not being able to perform self-function Windows update automatically.

W32.Fiala.Worm also belongs to the gateway virus, so it controls the entire process of exchanging data of computers on the same network, inserting iframe containing malicious code into the content of web pages, before They are returned to the user's computer. In addition, the W32.Fiala.Worm-infected computer also has a hang-up in about 10 to 15 minutes each time the user performs a shutdown operation.

If the computer is infected with W32.Fiala.Worm virus, users can download the latest version of Bkav to handle the virus. Also, to restore Windows Automatic Updates feature, users can access the following address to reinstall ActiveX Windows Updates. The ActiveX installation will restore the standard wuauclt.exe file to the operating system.
