Rogue:Win32/Onescan is a computer virus, which pretends to be a legitimate security program and claims that malware has been detected on your computer. If you try to remove these infections, Rogue:Win32/Onescan will state that you need to buy its premium version before being able to do so.

Rogue:Win32/Onescan targets users browsing Internet websites, and rely on social engineering to deliver its payload.
On infected or hacked websites users are prompted by a pop-up window that has been carefully crafted to resemble a legitimate security warning. These pop-up windows typically alert a user of a computer infection, and then prompt the user to download and install Rogue:Win32/Onescan to resolve the apparent issue.
Some of the infections may have come from users downloading an infected codec file when they were trying to watch a video online, or users who receive a spam email and open an infected email attachment.

The rogue is branded and distributed as various names including, but not limited to, the following, to avoid detection: alphavaccine, anycop, bestvaccine, bizvaccine, bluevaccine, boandefender, boanguard, boaninfo, boankeeper, boansupporter, boanupgrade, Bootcare, checkvaccine, cleanvaccine, coolspeed, DASearch, defencevaccine, directvaccine, diskvaccine, doublevaccine, DoubleVaccine, easyboan, easyvaccine, EnPrivacy, everyclean, everyguard, EveryGuard, fastcure, fastpc, fastvaccine, firstvaccine, goodvaccine, gvaccine, HardScan,highclear,highvaccine, homevaccine, infoclear, InfoData, InfoDoctor, InfoHelper, infosave, internetspeed, keepprotect, lifeclean, lightpc, litevaccine, livepc, livesafer, mastervaccine, microboan, multicare, multivaccine, MyKeeper, mypcclean, mysafer, myvaccine, MyVaccine, neovaccine, netvaccine, One Scan, onescan, pcboan365, PCTrouble, pcupgrade, perfectcure, pointvaccine, powerboan, powercure, primevaccine, proguard, proscan, provaccine, purevaccine, realchecker, realcleaner, realsecurity, searchvaccine, Siren114, smartmode, smartsafer, smartspeed, SmartVaccine, solutionpc, specialguard, speedcheck, speedcontrol, speedcure, speedplus, speedsolution, speedtools, speedvaccine, sweeperlab, topboan, topchecker, topvaccine, totalvaccine, UProtect, userboan, userprotect, UtilKorea, UtilMarket, vaccinecode, vaccinecom, VaccineCure, vaccinefree, vaccinehelper, vaccinekiller, vaccinenet, vaccineon, vaccinepc, vaccinepower, vaccineprogram, vaccinesafe, vaccinesafer, vaccineupdate, vaccinezero, vcboan, vcmanager, windowcure, windowguard, windowvaccine, WindowVaccine, wisevaccine, WiseVaccine, XProtect, zerocop or zvaccine.

The installer creates a folder, using one of its variant names, under the %ProgramFiles% folder. In the wild, we have observed folders named in both Korean and English.
[Image: Rogue:Win32/Onescan installer]
The downloaded files are installed to %ProgramFiles%\<product name> (for example, %ProgramFiles%\vaccinepc\).

  • <product name>.exe – main scanner component
  • <product name>u.exe – component that checks for updates
  • <product name>start.exe – component that launches the scanner component
  • <product name>d.dll – configuration data (not a DLL)
  • uninst_ <productname>.exe – uninstaller
  • EGutil.dll

For example:

  • vaccinepc.exe
  • vaccinepcu.exe
  • vaccinepcstart.exe
  • vaccinepcd.dll
  • uninst_vaccinepc.exe

The <product name>start.exe component monitors whether other executable components of the malware are running, and may re-launch them if not.

Once installed, Rogue:Win32/Onescan will display fake security alerts that are designed to think that your data is at risk or that your computer is severely infected.These messages include:

Warning! Your computer is infected!
Highly possible that you may lose all the data.
Your personal data can get to third parties and all your files can be removed during the day and you can have other problems.

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.

    updates-guide

    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    warning sign

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    backup sign

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    lock sign

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.

    cursor sign

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. Don't use pirated software.

    Shady Guide

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.
