Yixspeedup Virus


Yixspeedup is a malicious piece of software that can be described as a representative of the Trojan horse virus category. Yixspeedup targets Windows computers and forces them to run different harmful processes that could damage the computer and/or compromise the user’s virtual privacy.


The Yixspeedup virus is an unwanted program.

It is in your best interest to scan your computer for malware if you suspect that Yixspeedup may have attacked you. Usually, newer Trojans such as Yixspeedup, SAntivirus or Segurazo wouldn’t normally trigger any obvious infection symptoms. Still, it is possible that you may notice some irregularities in your computer’s behavior that may lead you to think that there may be a Trojan in the machine. One very important thing to remember here is that, even if your antivirus hasn’t warned you about the presence of malware on the computer, this doesn’t necessarily mean that there isn’t an ongoing Trojan horse infection. Since the majority of antivirus solutions rely on their extensive databases in order to recognize an incoming malware attack, newer Trojan horse versions that are not yet added to the database of a given antivirus program won’t get recognized by the security tool and would likely be able to enter the computer without getting noticed. That being said, here are some possible symptoms that a Trojan may sometime trigger:

Yix Speedup

Changes in the system settings and in the setting of some of your programs and apps could be an indication that there’s some unwanted and/or potentially dangerous program like Yix Speedup is on your computer. Yix Speedup oftentimes tamper with different system and software settings in order to push their agendas so it’s important to keep an eye out for any modifications that you haven’t approved.

Sudden errors, freezes, and blue screen crashes can oftentimes e an indication that there is a Trojan horse virus in the system. Since Trojans oftentimes run processes that can destabilize the system, crashes, errors, screen freezes, and other similar disturbances are quite likely to occur.

One additional symptom is if your computer is using large amounts of its resources (RAM, CPU, GPU) in order to run a process that doesn’t seem to be tied to any of the programs you are currently using and it also doesn’t seem to be a regular background system process. You can get more information about this from the Processes’ tab of the Task Manager so we advise you to check this if your computer has been unusually slow lately.

Trojan viruses are versatile cybercrime tools and their abilities could be highly varied. You can expect anything from espionage and data theft to remote control of your system’s functions that allows the hackers to start new processes on the computer without your permission. It’s even possible that additional threats such as Ransomware or Rootkit viruses enter your computer with the help of the Trojan as some of the Trojan horse infections can serve as backdoors for other malware programs. Currently, the information about Yixspeedup is insufficient to determine the exact mission of this threat. Still, it’s best to remove it ASAP and the guide that is posted below will show you how you can do this from your home.

How to Remove the Yixspeedup Virus

In case you have recently installed a certain program on your PC that you think may be responsible for infecting you with Yixspeedup, our first suggestion on how to remove this malicious Trojan is to uninstall that program. You can see all programs installed inside your computer from the Uninstall a Program window that you can access through the Start Menu and there, you can find and delete the program you suspect of being linked to the Trojan.

To reach the Uninstall a Program window, type “uninstall a program” under the Start Menu and click on the first shown result. Then sort the list of programs by date to see the newest/most recently installed ones at the top and then look for items installed around the time you think the Trojan Horse infection may have occurred. If you think you know which program is responsible for the presence of Yixspeedup on your computer, click on that program and then on the Uninstall button at the top.

  • Naturally, if there is a program named Yixspeedup listed in that window, you must uninstall it.

Uninstall A Program

Next, agree to the uninstallation and follow any prompts that may get shown on your screen. Remember to read everything carefully and uninstall all components of the unwanted program, including any personalized settings for it. Also, if a window like the one from the next image appears on your screen during the uninstallation process, select No or else you’d probably end up with more malware on your computer.


Restart the computer after the uninstallation finishes and use your PC for a while to see if there are any remaining signs of the Trojan. If you think the virus is still in the system or if you were unable to uninstall the program responsible for the infection with it, you should complete the next steps of this guide to fully eliminate all data linked to Yixspeedup from your machine.


The first thing you ought to do when your goal is to find and eliminate a Trojan virus from your PC is to check the Task Manager of your computer and try to find the process(s) run by the virus program. You can search for the Task Manager in the search field of the Start Menu and open it from there or simply evoke it using the Ctrl + Shift + Esc keyboard combination.

Once the Task Manager is in front of you on your screen, go to its Processes section – there you will see listed all the processes that are running on your computer at any given moment. If any of those processes look unfamiliar, consume large amounts of virtual memory (RAM) or processing power (CPU), and/or are not run by programs that are presently open on the computer, then those processes may be related to the Trojan and you may need to close them.

Before you do that, however, first Google the names of those processes on the Internet and see what information you can find. In some instances, it may turn out that a process you deem suspicious is actually an important OS processes, in which case you should definitely not close it.

Next, right-click on the suspicious process(s) and select the Open File Location option and scan the files you find in the file location for malware.


If you have an antivirus or an anti-malware program on your computer, you can use that for scanning the files, but we also suggest you try out the next free malware scanner that we have prepared for our readers:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    If during the scanning process any of the files you test is flagged as malware, then go back to the Activity Monitor window, click on the process you suspect of being related to Yixspeedup and then select the End Process button to end it.

    Afterwards, you must delete the whole folder (file location) where the files of the process are stored. If any of the files there cannot be deleted for whatever reason, delete the others and move on to Step 2. Once all other steps from this guide have been completed, you must remember to come back here and try again to delete the remaining files. By that moment, you should have no problem deleting them.



    In this step, you must reboot the computer into Safe Mode – a mode in which the Trojan’s processes shouldn’t be allowed to run which would hopefully make the removal of the virus easier. You can learn how to start the computer into Safe Mode for different Windows versions from this guide.


    Open the Start Menu, type System Configuration, press Enter, and select Startup in the newly-opened window. If any of the listed startup items seem like they could be related to Yixspeedup or are from programs you do not recognize and/or from programs with “Unknown” in the Manufacturer column, uncheck those items and then select OK.



    Copy this line: notepad %windir%/system32/Drivers/etc/hosts, and paste it under the Start Menu. Open the file that shows up in the results (if there are more than one, click on the first result) and then look at the bottom part of the text in the notepad document that opens. There should be a line where it says “Localhost” – if there are any lines/IP addresses written below this, copy them and send them to us as a comment on this page. After we take a look at them and determine if they are likely to be coming from the Trojan, we will reply to your comment and you will know what to do next.

    hosts_opt (1)

    If we tell you the IPs listed in your Hosts file are not supposed to be there and are probably from Yixspeedup, you will have to go back to that file and manually delete those IP addresses, saving the file afterwards.


    In this last step, you must access the computer’s Registry, find all items linked to Yixspeedup stored in it, and delete them. In some cases, it may be difficult to tell if a given Registry item needs to be deleted and if you delete the wrong thing, your computer may become unstable and there could also be other unforeseen consequences for your system. Because of this, when in doubt, write us a comment first explaining your situation, so we can tell you what to do next.

    Now, a quick way to open the Registry Editor is to press the Winkey and the keys from your keyboard, type regedit, and hit the Enter button. You will be asked by your PC to give your Administrator permission to start the Editor so click on Yes to do that. In the Registry Editor, select the Edit menu and then the Find option. Type the name of the Trojan Horse and select the Find Next button to search for items with that name. If anything with the Yixspeedup name is found, select that item, press Del from the keyboard, and then click on Yes to confirm the deletion. Repeat the search for Yixspeedup in the Registry and delete the next found item, rinse and repeat until there’s nothing left in the Registry that is named Yixspeedup.

    Lastly, you must manually check the next Registry locations for suspicious folders. By “suspicious folders” we mean ones that have unusual and suspicious-looking names – names that are very long and consist of letters and/or numbers that seem randomly arranged. If you find folders that you think match this description or any other ones that, too, look questionable, you will need to delete them. However, it might be better if you first told us what you have found in these Registry locations so that we can confirm that you must indeed delete those items.

    • HKEY_CURRENT_USER > Software
    • HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Run
    • HKEY_CURRENT_USER > Software > Microsoft > Internet Explorer > Main

    Once you have completed this final step from the guide, remember to go back to Step 1, open the File Location of the Trojan’s process, and delete the files that you weren’t allowed to remove before (if there are any such files left).
