Although many users have changed their online habits, they haven't necessarily fixed their machines, even as infected computers slow, often to a crawl. Twenty percent of users who had computer problems did not attempt a fix. Among those who did, 29 percent waited a month or longer. Two in five who tried to fix their machines did so on their own while others needed help from a friend, family member or a professional repair shop. In 20 percent of cases, the problem couldn't be fixed. http://www.washingtonpost.com/wp-dyn/content/article/2005/07/06/AR2005070601...
