"HARDDISK_ROOT KIT_TROJAN_HIJACK.EXE" removal instructions
What is "HARDDISK_ROOT KIT_TROJAN_HIJACK.EXE"?
"HARDDISK_ROOT KIT_TROJAN_HIJACK.EXE" is a tech-support scam that displays a fake virus alert and encourages users to contact "technical support" by calling the telephone number provided. Criminals use these scam pages to generate revenue by tricking people into paying for software or services. These sites are often opened by potentially unwanted applications (PUAs) installed on the system. Do not trust these websites - simply ignore them.
This scam is displayed on a web page disguised as an official Microsoft site, however, this company has nothing to do with it. According to information on the site, the user's computer is blocked, since the web page has detected a virus ("HARDDISK_ROOT KIT_TROJAN_HIJACK.EXE") that caused the "o0acxfasf" error. It is also stated that the user's Windows registration key is illegal, and that the operating system is hacked and is proliferating viruses over the Internet. To "reactivate" their computers, users are encouraged to contact a "Microsoft helpline" by calling the "+1(888)759-7475" telephone number. This scam also shows a pop-up window disguised as a notification from "SmartScreen". According to this pop-up, Windows SmartScreen has prevented an unrecognized app ["windows10manager (1).exe"] from starting and that this might put the computer at risk. It also encourages users to call "technical support" via the number provided. Remember, this is a scam that often tricks people into believing that their computers are infected or at risk. People who contact scammers via the telephone number are encouraged to remove viruses or fix other problems with paid software or using online services. Websites of this type should not be trusted. If the site cannot be closed normally, end the browser process through Task Manager. Note that restoring the previously-closed session will reopen the same scam page. When this scam is opened in full-screen mode, it can be exited by pressing the "Esc" key.
In many cases, scam web pages (and other untrustworthy sites) are opened by potentially unwanted apps (PUAs) installed on the browser or operating system. In addition to unwanted redirects, PUAs usually gather details relating to users' browsing habits and display deceptive, dubious advertisements. PUAs also collect users' IP addresses, geolocations, URLs of visited sites, entered search queries, etc. Developers share this data with other parties (possibly, cyber criminals) who misuse it to generate revenue. Furthermore, PUAs often display ads (coupons, banners, surveys, pop-ups, etc.) that lead to dubious web pages or even unwanted downloads/installations.

The Internet is full scam sites. Some other examples include "Windows Antivirus - Critical Alert", "Hard Drive Safety Delete", and "Virus Support Alert". None of these should be trusted. Often, they promote dubious applications or encourage visitors to call numbers that lead to scammers. PUAs that open these pages are usually advertised as legitimate, useful applications, however, they cause a number of problems (issues with privacy, browsing safety, and so on) and deliver none of the advertised features.
How did potentially unwanted applications install on my computer?
In some cases, potentially unwanted applications can be downloaded from their (supposedly official) websites, however, most are promoted and distributed via a deceptive marketing method called "bundling". Developers use this to trick people into installing PUAs with other, regular software. They hide PUAs in "Custom", "Advanced" or other similar settings of the software download/installation set-ups. In most cases, these PUAs are downloaded and installed when users download/install their chosen software without checking the settings. In other cases, it happens when they click dubious ads that run scripts designed to cause download and installation of potentially unwanted applications.
How to avoid installation of potentially unwanted applications?
Use official and trustworthy websites or other sources to download software. Third party downloaders/installers, dubious web pages, Peer-to-Peer networks, and other similar sources should not be trusted. These channels are often monetized by promoting PUAs or other, potentially malicious and rogue apps. Install software with care - do not complete any setup steps without checking "Custom", "Advanced" and other similar settings. Opt-out of offers to download or install potentially unwanted apps, and only then finish downloading or installing software. Do not click dubious ads, especially if displayed on dubious unofficial web pages. These ads can redirect to untrustworthy or potentially malicious websites (such as gambling, adult dating, pornography etc.). If unwanted redirects or ads occur regularly, check your browser for any unwanted/dubious extensions, plug-ins, or add-ons, and remove them immediately. The same applies to the programs of this type installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
