‘Welchia’ virus clogs library’s computers

Let This Be a lesson for all of us.

On Monday, computers in the San Antonio city’s library system were slowed by the virus that generates so much network traffic that accessing the Internet and other operations become impossible.

By Tuesday afternoon, library computers had become inoperable and librarians lost the ability to check the automated catalog to see if a book was in stock, computers used by the public were shut down, and books had to be checked out manually.
