But a US ad firm has come up with a genius virus that could actually help you, especially if you feel like having a lazy day at the office, reports The Daily Dot.
It's called the Happy Hour Virus but it doesn't actually infect your computer with malware - it's all an elaborate hoax. You can choose between three problems depending on your desired bludge time and your computer model - broken monitor, kernel panic or blue screen of death.
Your web browser will launch in full-screen mode, making it look like your entire computer has been compromised. Just press "esc" and your computer will return to normal.
The virus can be launched via the website of Colorado ad agency TDA_Boulder. The company say they're trying to encourage us to work less and have more fun.
"We are all better employees if we achieve something called a work-life balance. However, pursuing that goal is not always an easy task in today's corporate culture," reads their mission statement.
"Please use the Happy Hour Virus to leave work early and enjoy the company of friends, family or co-workers. We are aware that this might jeopardise your productivity the following day, but we are willing to take that risk on your behalf.
And as long as the IT guy or your boss don't catch on, you'll be at the pub in no time.
