A victim complained about it like this
"I started getting error messages yesterday saying "Microsoft Detected Security Error, Due to Suspicious Activity Found on Your Computer. Contact Microsoft Certified Live Technicians 0-800-098-8545" I also noticed I was being redirected to hurryupsearch.com when I used Internet Explorer. No problems in Firefox. Then I got several "Warning" messages about different software on my computer with similar odd type and wording. After trying to leave the page the browser froze."
What is Hurryupsearch.com?
Hurryupsearch.com comes to your PC as a webpage with the problems of your PC. It seems that the information is sent by Microsoft, right? Many users think so. So they all end up with leading problems to their PCs. This page is actually supported by an adware. It warns users about the problems of their PC and asks them to call with the provided number. If a victim is fooled by it, it can drain money from his phone bill and promote its products or services during the phone call. Usually, you may get this adware through free downloads. Some viruses or malware may also bring it to you. And it can keep sending you unwanted ads and fake messages. And the adware is powerful enough to infect browsers like Internet Explorer, Mozilla Firefox, Google Chrome and Safari. You should not take it slightly.
