TUCSON (KGUN9-TV) - We have a warning that affects millions of people. And that's no exaggeration.
Millions of people whose computers use Windows XP are more vulnerable to hackers as of Tuesday because Microsoft has stopped plugging the holes hackers exploit.
So what can you do about it?
If XP is in your computer it'll still work, but if you go on the internet, you're more likely to surf into trouble than ever.
Now after that long, XP boot up, you'll see an ominous warning.
A box says XP end of support is April 8th----that's this April 8th. That means Microsoft will stop plugging the holes that help hackers steal your personal info in that box.
Stephanie Polk came to Computer Renaissance for a computer with a newer version of Windows Microsoft still protects.
"Maybe some people might not want to believe it but I don't want to find out the hard way."
Computer Renaissance owner Rich Flieger says security holes mean XP users will still be at risk even with up to date anti virus.
He says most customers decide even if their computer has enough oomph to run newer software it's senseless to pay about 120 dollars to put new software in an old machine.
But any upgrade is tough for businesses that may have dozens of computers.
"It's quite a pill to be able to swallow to upgrade all those machines in a timely manner and the financial outlay is significant so it's tough on them."
If you're comfortable tinkering with computers you could try one of the many versions of a free operating system called Linux. Many versions run well on older computers but you'd better be comfortable with computers because if you have trouble your only option may be to ask around on the internet.
