Taskeng.exe Virus – How Was I Infected?

In case you see a weird black command prompt window that starts and closes on system startup with the name taskeng.exe error or the process uses up unusually high percentage of your CPU to run, you may have been infected with malware.

One way to get infected is by clicking on or being redirected to malicious web links that may have been from online advertisements on third-party sites or administered by unwanted programs (PUPs) on your computer. Some websites that contain malicious code perform a drive-by download on your computer and insert the malware directly in it without any permissions what so ever.

However, there is also the possibility you may have downloaded malware disguised as a java or flash player update or any other software, believing it is legitimate. Sometimes malware hides on downloader programs for other software. One example is if you are looking for a particular video to download online and instead you have downloaded a file that says something like ‘video_downloader.exe’ that may, in fact, be the malware. This is why experts always advise not to be in a rush when you are looking for something online and always to check the sources. In case you cannot identify a malicious site, it will help to have an online security extension in your browser, like Virus Total or Avast, for example.

Another way to become a victim of this virus is via social media. A lot of social media bots spam fake status updates from your friends’ names(in case they are infected) or directly send out messages to users.

More to it than this virus may be executed as a result of a man in the middle attack (MITM) directly on your computer in case other users had access to it.

The most often reported cases of virus infections, however are the ones with documents, mostly Microsoft Office ones that are combined with the malware in them. They come in spam or spoof mail attachments that rope the user into opening the file. Fortunately, a good way to prevent this is to use an email program, such as Microsoft Outlook or Mozilla Thunderbird on your computer that filters out spam mail.

    How to Protect Yourself in the Future

    Cyber-crooks have become very smart in both developing viruses as well as methods of infection of users. Both home users and enterprises should beware and always apply the following advises to the PCs in their networks:

    • Make sure to use additional firewall protection. Downloading a second firewall (like ZoneAlarm, for example) is an excellent solution for any potential intrusions.
    • Make sure that your programs have less administrative power over what they read and write on your computer. Make them prompt you admin access before starting.
    • Use stronger passwords. Stronger passwords (preferably ones that are not words) are harder to crack by several methods, including brute forcing since it includes pass lists with relevant words.
    • Turn off AutoPlay. This protects your computer from malicious executable files on USB sticks or other external memory carriers that are immediately inserted into it.
    • Disable File Sharing – it is recommended if you need file sharing between your computer to password protect it to restrict the threat only to yourself if infected.
    • Switch off any remote services – this can be devastating for business networks since it can cause a lot of damage on a massive scale.
    • If you see a service or a process that is external and not Windows critical and is being exploited by hackers (Like Flash Player) disable it until there is an update that fixes the exploit.
    • Make sure always to update the critical security patches for your software and OS.
    • Configure your mail server to block out and delete suspicious file attachment containing emails.
    • If you have a compromised computer in your network, make sure to isolate immediately it by powering it off and disconnecting it by hand from the network.
    • Make sure to educate all of the users on the network never to open suspicious file attachments, show them examples.
    • Employ a virus-scanning extension in your browser that will scan all the downloaded files on your computer.
    • Turn off any non-needed wireless services, like Infrared ports or Bluetooth – hackers love to use them to exploit devices. In case you use Bluetooth, make sure that you monitor all of the unauthorized devices that prompt you to pair with them and decline and investigate any suspicious ones.
    • Employ a virus-scanning extension in your browser that will scan all the downloaded files on your computer.
    • Employ a powerful anti-malware solution to protect yourself from any future threats automatically.
