Avoid getting scammed by websites showing a fake "High Priority" message
Written by Tomas Meskauskas on (updated)
What kind of scam is "High Priority Message"?
"High Priority Message" is a fake error message displayed by a malicious website that users often visit inadvertently - they are redirected by various potentially unwanted programs (PUPs).
These programs usually infiltrate systems without consent. Research shows that, as well as causing redirects, PUPs deliver intrusive online advertisements and continually gather various information relating to browsing activity.
"High Priority Message" scam overview
The "High Priority Message" error states that the system is in a blocked state and that rebooting it might cause damage. Users are advised to contact "Microsoft certified technicians" via a toll-free telephone number provided. They are then supposedly guided through the entire process.
The website is similar to Windows Blue Screen of Death (BSOD) and, therefore, the "High Priority Message" error may seem genuine, however, this error is fake and has nothing to do with Microsoft. Cyber criminals attempt to scare and trick victims into calling and paying for technical support that is not required. You can remove this error simply by closing the web browser.
PUPs also deliver intrusive advertisements. To achieve this, PUP developers employ various tools that enable placement of third party graphical content on any site. Therefore, pop-ups, banners, coupons, and other intrusive ads, often conceal underlying content, thereby significantly diminishing the browsing experience.
In addition, they might redirect to malicious websites or even execute scripts that download and install malware. Therefore, clicking them is risky and can result in further computer infections.
Another downside is data tracking. Research shows that High Priority Message continually gathers various information relating to browsing activity including Internet Protocol (IP) addresses, website URLs visited, pages viewed, search queries, mouse/keyboard activity, and geo-locations.
The collected data might contain personal details that PUP developers sell to third parties (potentially, cyber criminals who generate revenue by misusing private information). Therefore, the presence of information-tracking applications can lead to serious privacy issues or even identity theft. For these reasons, uninstall all PUPs immediately.

Similar scam examples
There are dozens of fake errors that share similarities with High Priority Message. The list of examples includes (but is not limited to) Unusual Activity, Warning! Malware Detected!, Your Computer May Have a Virus!, and Internet Security Damaged.
All claim that the system is damaged in some way, however, as with High Priority Message, these errors are designed only to trick users into paying for unnecessary services. They should not be trusted. PUPs are often virtually identical.
By offering various 'useful features', they attempt to give the impression of legitimacy, however, these apps simply generate revenue for the developers, whilst regular users receive no value. PUPs cause unwanted redirects (thereby promoting various websites), deliver intrusive online advertisements, and collect various user-system information.
Many of the promoted websites are fake search engines that generate fake results, deliver intrusive ads, and record information. As with intrusive ads, fake search results can also lead to malicious websites. Therefore, using a fake search engine might lead to serious privacy issues and high-risk computer infections.
How did adware install on my computer?
Some PUPs have official download/promotion websites, however, these programs are also distributed using a deceptive marketing method called "bundling" and via the aforementioned intrusive ads. Bundling is stealth installation of third party applications with regular (usually free) software/programs.
Developers are aware that users often rush the download/installation processes and skip steps. Therefore, they hide bundled apps within the "Custom" or "Advanced" settings. Skipping this section and clicking intrusive ads exposes systems to risk of various infections and compromises users' privacy.
How to avoid installation of potentially unwanted applications?
PUPs are distributed using the bundling method, and via intrusive online ads. Therefore, be cautious when downloading/installing software and browsing the Internet in general.
Download your software from official sources only and (if possible) choose a direct download link rather than using third party downloaders/installers (these tools usually bundle third party software - using them is very risky). When downloading/installing, select the "Custom/Advanced" settings, carefully analyze each step, and opt-out of all additionally-included programs.
Furthermore, avoid clicking ads. Criminals put a great deal of time and effort into making intrusive ads appear genuine. Thus, determining if they originate from the visited (legitimate) website is virtually impossible. No matter how tempting an ad may seem, do not take the risk of clicking it. The key to computer safety is caution.
