Some would consider me paranoid about computer security. As I run my business from home and my wife also does a great deal of on-line shopping, I feel the need to have my computers very secure. Question: Is a daily in depth scan too much? Can it be harmful in any way to my system? Is it unecessary? If so, how often would you suggest to scan all files for viruses and or to perform an in depth scan? PS...I also do a daily scan with Spysweeper. Even though neither program generally finds anything. Seeing the clean scan log seems to give me peace of mind.
