Computer Virus

I am back after a holiday break and a month full of computer viruses. I'm becoming paranoid and having a hard time believing they are gone and I am safe once more. I never realized how dependant I am on technology. After two scares where I feared all my work would be lost I have avoided working on the digital copy of my book. I have since done about all a person can do with a hard copy and desperately need my computer back to make the proper changes. I need to type on a keyboard!
