Yesterday, I published an article entitled Hundreds of Thousands May Lose Internet Access in July that warned of a malware (malevolent software) attack that is attacking Windows computers. Several newsletter readers questioned the accuracy of the warning. For those who want further information, I suggest you read the following:
