How to Remove Uc.exe “Virus”


This page is made to help you remove Uc.exe. The Uc.exe removal guide works for Chrome, Firefox and Internet Explorer, as well as every Windows version.

Uc.exe is an adware program. The rogue tool does not have an official name. For this reason, security researchers have named it after the process it runs in the Task Manager. Uc.exe is ad-supported. The secluded tool promotes the content of sponsored websites. It generates pop-up advertisements, listing bargain shopping deals. The reality is that these ads link to sponsored platforms which are not chosen by the program. The developers of Uc.exe agree to promote the content of all paying parties without running a security check. Any of the linked websites could turn out to be corrupted.

What are the consequences of Uc.exe running on your system?

Per definition, adware programs are created to raise monetary proceeds through supported advertising. This approach is not well regarded when the program neglects to take precautionary measures. Uc.exe does not filter the websites it links to. This makes the tool risky for the end user. Following the pop-up ads could take you to compromised websites and get your computer infected with malware.

The web page you are redirected to by following a given ad might not match the description from the window. This is quite common for unsolicited advertisements. The pop-up window displays a picture of a certain item, while the website it leads to is not connected to shopping at all.

In some cases, the user is required to sign in with an online payment account before proceeding to the website. You should never agree to enter your financial details when accessing a website. This is how phishing attacks are done. Cyber criminals can duplicate the layout of a legitimate payment platform and collect the login credentials you enter. The developers of Uc.exe may have nothing to do with this scheme, but they allow it to happen by redirecting users to unreliable websites.

Uc.exe can be involved in stealing your personal details. The shady program has tracking capabilities. It can record your surfing history, cookies, IP address, country of origin, zip code, email, user names, passwords and the personal details you have entered into your online accounts. The gathered data can be sold to cyber criminals.

How is Uc.exe distributed?

As already elaborated, there is not much information on Uc.exe. The furtive program uses a few dark patterns to gain entry into people’s computers. The most common distribution technique is bundling. The adware can merge its wizard with another utility and try to get installed in parallel with it. Pirated programs, freeware and shareware tools are the download clients for Uc.exe. When adding a program to your system, you should read its terms and conditions. Uncheck all extra tools, offered as a bonus.

Uc.exe can be transferred through a spam email with a host file. Mailing spammers spread clandestine software through attachments. The file can be infected with a malicious code to prompt the download and install of the adware when accessed. Make sure a message is legitimate before opening files from it. The entity behind the letter should have provided contacts. The listed information should match the disclosure on its official website.

Drive-by installations are another way of spreading Uc.exe. An insidious website or link can transfer the adware to your system through a single click. You need to be cautious about the sources you trust online. If you have doubts about the reliability of a given website, do your research on it. Be advised that malicious links can come from a reliable source when a hacker is involved. Make sure the person has sent the link himself. If you did not expect to receive a link from him, it is best to contact him.

  3. Hi Daniel. Mi laptop reboot every 30 second aproximately. I don´t have the time to do anything, I try by closing the suspicious process brom the task manager in the short time I have (when I do that the reboot delays a little), but still reboot mi laptop. When the UC.exe try to execute and windows ask mi if I gave my permission to execute the program doesn´t matter my answer, still reboot mi laptop. I look for the path where the file is hosting and it was in the program files in a folder named “hhh”, I deleted it but mi laptop still reboot, the only difference is that now windows ask me nothing. I looked in google chrome for suspicious extensions, I ended deleting all of them, I did that when I reboot mi laptop in safe mode, but in safe mode can´t acces to microsoft edge to look for suspicious extensions. In safe mode I also try all the options that the Recory gave me, but the Recovery system didn’t work. I have Avira but I can´t execute it in safe mode, so I can’t scan my laptop. I look in the uninstall programmes but I don´t find UC.exe maybe it´s disguised with another name.

    I conclusion, I don’t know what else to do. The only option I left is to install windows all over again.

    Many thanks for your time,

    • Hey Danilo,

      Please, try these steps:
      1. Boot Windows into Safe mode.
      2. I am not sure that Windwos version you are running.
      If you are running Windows 10, then click “Cortana” and type “regedit”. When asked click “Yes”.
      If you are running Windows 7, then click “Start”, “Run” and type “regedit”. When asked click “Yes”.
      3. In Registry Editor, click Edit -> Find and type uc.exe
      4. Write down all registry entries that have uc.exe as data. Post them as a reply of this comment. I will let you know if they are safe to be deleted.


    • Hey Ian,

      Yes, this is a bogus entry. Once you kill the uc.exe in Task Manager, you can navigate to C:\Program Files(x86)\sbqh and delete the whole sbqh folder. Also, make sure that you remove that entry from the Registry too.

  7. Hi Daniel,
    I followed all the mentioned steps but I still find multiple instances of the UCBrowser in Prefetch, Tasks, Local and WinSXS folders. When I try to delete them it says that I do not have permissions.
    What can I do?

  8. I uninstalled UC browser in safe mode, but the default browser appears UC followed by Chinese characters. How can I remove and there? And 2 when I want to create a folder and explore Windows restarts will not let me do that. How can I solve these problems?
