computer

  

       My friends also live in this small box. But one day I found the box got hot.

I clicked the open button but in vain. They got a virus! I saved all of them to my new portable hard drive because I had to delete everything and reinstall Windows to make sure they would be safe there. To avoid getting the bugs again, I bought an anti-virus program for it.  I'm also thinking about adding more memory  to improve their living environment.  With a larger capacity, they can be more stable and comfortable without popping up unexpectedly and running away, and leaving me an error message.  Are there any other special programs that my control panel can install?
