I am using two cpmputers one in my home with an internet connection and the other in office with no net connection.I sometimes do my office works in my home computer and transfers the files to the office computer using my pen drive I also uses my pen drive to download important government orders from net and transfer to the office computer Now my Office Head disallowed me to connect my pen drive to the office computer stating that it will cause the virus to enter the Office computer from my home computer He also drected to use CDs to transfer files from my home Is there any truth in his argument ? Is it safe to use CD to transfer files and is there any danger to use pendrives in my case ? I also inform that my home computer works in good condition and have anti virus protection
