More details about W32.Tvido.A

Once the W32.Tvido.A was already executed, the worm will spread and propagate by infecting the files on the victim machine. When the file that was infected was opened or being executed by the user, the worm tries to find for another file that was also infected having .exe extension on all of the network drives that are available and all the local drives. The virus also may prevent the files from infecting on the system drive. The virus also adds the marker “WeeD v1.1 Made in Belarus!” in the header of the MS DOS of the files that were infected.

The installation of the W32.Tvido.A application may incorporate a modification to the Registry value that allows it to load during the start-up process of the operating system. It is also possible that this malware will drop some files with random filenames in assorted locations with the user's knowledge or permission. Aside from dropping some files, it is quite possible for other variants of the W32.Tvido.A program to drop other malicious program that will compromise the function of the infected computer.
