removal by Ugnius Kiguolis - - | Type: Adware

Internet Optimizer is an adware program that relies on internetoptimizer.exe to run in the system's background

Internet Optimizer virus
Internet Optimizer is an adware program that promotes other bogus applications and gives no value for the system.
Internet Optimizer is a malicious program which, once installed, starts redirecting its victims to questionable sites. The cyber threat is related to DyFuCa – spyware used to collect users' private information. It also has secondary functions like malware downloader and installer. A fake optimizer can easily install additional content, like browser extensions, plug-ins or add-ons, on the system to be able to show various advertisements when you browse the Internet. Once attached to your web browser, InternetOptimizer generates numerous advertisements including such slogans: “Ads by XXX,“ “Brought to you by XXX,“ “XXX Ads,“ “Powered by XXX.” Make sure you ignore them to protect yourself from redirects to infected websites.

  • Delivers numerous pop-up ads;
  • Installs bogus extensions, and unsafe programs;
  • Causes system crashes 
Affects Every browser installed on Windows OS
Distribution Malicious websites, software bundles, deceptive ads
Elimination Use Reimage for general system cleaning

The application has been promoted as a legitimate tool that is beneficial for computer's speed and well being. However, despite the attractive appearance and catchy offers, the PUP brings no positive features. These links it displays are shady and can reroute you to malicious websites offering you to install free updates or fake optimization tools. 

Another harmful effects related to this adware is that it slows down your device because it uses numerous system's resources to generate pop-up ads. If you're interested in the computer's security experts opinion, it is strongly recommended to avoid clicking on these pop-up windows, banners and different commercial content because it can result in the installation of additional malware on your computer.

The main reason to avoid clicking on these advertisements is that it may result in the automatic execution of another virus. Unfortunately, Internet Optimizer virus has already been found to be related to a malicious DyFuCa virus categorized as spyware. The program is known for collecting users' information and then misusing it for developer's needs. Your email accounts or messaging applications can be accessed what can lead you to privacy issues.

DyFuCa's relation with Internet Optimizer makes this PUP even more dangerous. In addition to various changes in the system, the spyware drops certain files and becomes even more persistent:

  • srvbwfwngw.exe;
  • srveghcxhp.exe;
  • offun.exe;
  • tcb.pmw.

As you can see, Internet Optimizer virus is not a tool you want to keep on your computer. It has no pros and causes numerous problems by running its malicious process in the background and trying to gain profit[1] by displaying numerous ads.

You should remove Internet Optimizer because of the following reasons:[2]

  • each click on the browser creates new tabs or windows with commercial sites;
  • the virus injects commonly visited sites with banners and similar commercial content;
  • it tracks users' searches and collects NPII.

Employ a trustworthy anti-malware for Internet Optimizer removal and clean the system to make sure that there are no compromised files left. Remember to fix issues with your browser by setting everything back to default. You can find a few program suggestions and tips for browser resetting down below.

Malware creators spread adware silently via deceptive ads and software bundles

Nowadays, the creators of unnecessary advertisement applications are very creative when it comes to spreading these programs seamlessly. They tend to use a popular and tricky freeware marketing method – bundling. It means that with some at first glance harmless program you will also receive additional applications, plug-ins, add-ons or browser extensions. You will probably won't even notice when did you decide to authorize the installation of this content – most likely you rushed and didn't choose the right installation settings.

The developers of freeware and shareware conceal additional applications under Standard or Default options. If you want to decline the installation of such additional content, you should always opt for Custom or Advanced mode. When the window expands, untick all boxes that suggest additional applications, plug-ins, browser extensions, as well as changes to your default web home page.

When it comes to more prominent and dangerous cyber threats which this PUP might be related to distribution ways are similar. However, dubious pages ask to enable processes or installations and agree to terms and conditions. You shouldn't agree to anything when browsing questionable sites. Keep anti-malware tools on the system so you can be indicated each time something possibly malicious happens.
