Key notes

This messageThe requested resource is in uselooks harmless when it first pops up on your computer screen. But, if it appears on your PC every time you try to open a program, it should worry you.

Theerror messageis usually a warning for something quite serious – a Trojan horse malware that is calledSmartService.

TheTrojan horse‘s name is, sadly, well earned. The malware behaves in a very smart way, from the multiple ways it can worm itself onto your PC and expose it to threats.

Like other destructive malware, its strain can leave a trail of damage that includes: installing programs that steal your personal information, spying on your online activity, and relaying the data to hackers.

This all sounds scary. But theTrojan‘s reign of terror does not end there. Without a doubt, its most destructive effect is the ability to block theantivirus softwareinstalled on your computer.

By doing this, the malware opens the door for other viruses and malware to infect your computer.

The compound effect is your computer becomes an inlet through which cybercriminals can have free passes over your banking and other personal information.

Because of this ability to infiltrate computers and, at the same time, disabling their malware defenses, SmartService is often the weapon of choice for ransomware attackers.

It also messes with your browser. Your browsing experience will be characterized by constant popups, annoying redirects, and dubious browser extensions.

From the point your PC gets infected, the virus can sit there for a long time before you even notice anything unusual.

During that whole time, theTrojanwill be busy at work, stealing your personal information, spying on you, and installing vicious software on your computer.

It is thus horrifying to imagine the malware may already be done with whatever malicious act it was charged with by the time you detect it.

In this article, we’ll discuss ways of removing theTrojanif you have unfortunately been hit already. First, let’s look at the ways the malware can infect your computer.

Seeing how difficult it usually is to detect thisTrojaninfection and how destructive it is, prevention is indeed better than cure, in many ways than one.

SmartService can infiltrate your PC in any one of the following ways: malicious attachments to emails delivered to your inbox, or ads you click on the websites you visit.

You can also get it from infected files you install as part of the software downloaded from the Internet, content you download from social media, cookies on torrents’ platforms, and other freeware sites.

However, many apps can’t be completely removed. Thus, we recommend you to use any of thesebest uninstaller softwareto get rid of residual files left behind.

4. Scan the System Configuration folder for malicious software

You will be able to permanently delete them using the regedit solution we will discuss later.

Most malicious malware strains are so hard to detect, and such a pain to remove because they attach themselves to your PC’s startup folder.

As soon as you start your machine, these apps are up and running. This SmartServicetrojan horsebehaves in the same way.

You thus must make sure to scan the Startup folder and remove all suspicious-looking programs from there. This is an important step, as even the really good antiviruses may still get blocked.

But sometimes you don’t know what thetrojan‘s name is. You will thus need to manually search for all suspicious-looking programs in all folders withRunin their title.

Once you are in theCurrentVersionfolder, look for all folders with Run in the title. It can be Run, RunOnce, or others. Click once on each to reveal all the programs in the folders:

Scan the listed files and look for suspicious names, which you feel could be malware. If you are unsure about any, look them up before deleting them.

Trojanslike this SmartService, that leads to theerror messageThe requested resource is in useare difficult to detect, and a pain to remove.

This includes portable USB drives and external hard drives. There are manyUSB flash drive antivirus solutionsthat you can use. Also, avoid torrents and other freeware sites with questionable security.
