Your anti-virus software may have glitched your computer and you may not even know it.
On Wednesday, a faulty program by the McAfee software caused PC problems all across the country, including Kentucky.
But a least one computer expert says for some, the problem may last a few more days.
"You would just be sitting here and your internet would disappear, your PC would slow down and you wouldn't know why," explained Kyle Springer, CEO for Support Nerds, of Bowling Green.
It's a problem that's kept Springer busy since Wednesday.
"It's just been ramping up since," he said. "It will probably go through the weekend because some people probably still don't know what the problem is with their PC."
Springer is the head of a Bowling Green company called Support Nerds.
He says his company has taken 30 to 40 calls a day regarding a glitch stemming from the anti-virus software, McAfee.
"Somewhere in their programming they had messed up and completed what's called a 'false positive,' where it actually deleted a Windows file and disables your internet," he said.
The glitch struck government offices, schools and even some hospitals across the country.
And while according to McAfee, the problem only affected corporate customers, Springer says it's been the small businesses that continue to suffer.
"They don't have an IT department, so when they have these issues it's just as if they're at home," he said. "They don't have an IT person to go to and they don't know what the problem is, so business is down and they're losing money."
Other computer repair shops we spoke to say they haven't seen many problems from the glitch.
They add that they do tell their customers just to avoid McAfee software all together because of problems.
McAfee has posted fixes to the problem on its website.
