What are the speakers mainly discussing?

W: Sean, make sure you have your virus protection running at all times. Maria got a virus yesterday and lost some of her work. Now she has to reinstall everything on her computer.
M: That’s too bad. It happened to me once at home last year. I got one of those worms that erased everything on my hard drive. After that, I’ve always made it a habit to check my computer when I start it up.
W: Good. The tech department is supposed to install new anti-virus software starting tomorrow.
M: They should. It doesn’t take that long to do, and it’s better to be safe than sorry.
