Users don't fix their computers

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.
