Cyber-criminals are taking advantage of underground ad network to display an ad, which appears to be a legitimate system warning. Normally, the pop-up ad contains warning that a certain program is due for an update and neglecting it would cause serious damage to the computer. It entices web users to immediately download the software update to avoid the negative effects. Hence, installing the supposed software update will instead load MegaGuard on the computer. Similar doubtful programs as GuardGo, FindQuest, and Page Summarizer are also using the same tactics to infiltrate the computer.
