(InfoWorld) – “Microsoft has published a security advisory warning Windows users of a file-trashing worm that has been circulating via e-mail for several weeks. The worm, which is programmed to destroy a wide variety of files on the third day of every month, has been circulating since mid-January, and is estimated to have infected between 250,000 and 300,000 systems worldwide.”
Almost missed the monthly warning: DO NOT open files or click links from untrusted sources. THERE ARE NO TRUSTED SOURCES. Verify the sender really sent you the file. Scan it with a virus checker. Don’t use it if you don’t trust it.
