Internet Optimizer. How to remove? (Uninstall guide)

removal by Ugnius Kiguolis - - | Type: Adware

What is InternetOptimizer?

Internet Optimizer is an adware program, which, once installed, changes registry entries. This program installs additional content like browser extensions, plug-ins or add-ons in order to be able to show various advertisements when you browse the Internet. Once attached to your Internet browser, InternetOptimizer starts tracking your activity on the Internet. Based on your most visited web pages, bookmarks, and search queries, this potentially unwanted program generates advertisements for you. You can recognize this adware by the particular text under advertisement banners or pop-ups: „Ads by InternetOptimizer“, „Brought to you by InternetOptimizer“, „InternetOptimizer Ads“, “Powered by InternetOptimizer”. One of the harmful effects from this adware is that it slows down your network speed, because it uses resources to generate those ads. If you’re interested in the computer’s security experts opinion, it is strongly recommended to avoid clicking on these ads. Despite the attractive appearance and catchy offers, these links can redirect you to questionable and shady websites, which may offer you to install free updates, but most likely you are going to download infected files. Another reason to avoid clicking on these advertisements is that it may result in an automatic execution of a virus program. In order to secure your computer from adware and annoying, never ending advertisements that interrupt your browsing experience, we recommend installing a reliable and well-known anti-spyware program, like Reimage. It scans your computer, detects and eliminates computer threats.


How did InternetOptimizer hijack my computer?

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 a 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 made the decision to authorize the installation of this content – most likely you rushed and didn’t choose the right installation settings. Basically, 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. Use this information in the future, but if it is too late and you have already accidentally installed Internet Optimizer, our team is here help you to eliminate it.

How can I remove InternetOptimizer?

If you noticed the InternetOptimizer advertisements continuously showing up, you should waste no time and secure your computer. It is quite easy when you know how to do it. You can either download an anti-spyware and let it do its work, or you can try to uninstall the InternetOptimizer virus on your own. Our professional team has prepared circumstantial step-by-step instructions. Follow these guidelines below the article, and you’ll get rid of the irritative ads in no time.

  • Guest

  • Guest

  • Guest

    THis is the most pathetic speed optimiser one should ever download . I have to get rid of tis thing right away

  • Guest

    Thank you for the great advice on deleting this stupid freakin program. My virus software had it handled and caught it before it did any damage but it was annoying none the less. I appreciate the help.

  • Guest

    Try not to download extra stuff and do it the way peter suggested – simple and you dont have to worry about possibly downloading more bugs

  • Guest

    your advice was the best one i got and it was simple. thanks.

  • Guest

    Ok. im serching around on the net trying to find a way to deleat these viruses….
    atleast once a day AVG7 (grisoft antivirus program), pops up and tells me it has found a virus in “C:/Temp/optomiser.exe” the virus name is “Trojan Horse Downloader.Difica.3.R”
    And also “C:/Temp/NCasePackage.exe” supporting virus “Trojan Horse Dropper.Small.12.S”
    and obviously when it askes me what i wish to do, i choose to annihilate the files……

    But the point I am getting at, is that the file keeps coming back.
    I deleat C:/temp…
    there is no such thing as C:/program files/internet optimiser.

    What the hell is going on…. YES i can DELEAT OPTIMSER.EXE… but what i want to know is HOW DO I STOP IT FROM COMING BACK…

    because im guessing that for many people, this thing probably comes back, but they just dont know about it.

    for the file to keep coming back, generally means that there is Something ELSE, on my system that is causing the problem……

    GRRR i HATE VIRUS…. es…

    Does anyone ACTUAlly know how to fix this properly…

    My Machine Supports:
    – Spybot – Search & Destroy
    – AVGfree 7.(whatever the latest udate is)
    – Ad-Aware SE Personal
    – Registry First Aid
    – PC-Cillin…. non of these have fixed my problem properly so far, so dont say that they will….

    as of yet… AVG has been the best, because atleast it tells me when optimiser appears and trys to load, and i can get rid of it before it gets a chance.

    And this is not particularly important (getting rid of it is). But does anyone know what these viruses are ment to achieve?

  • Guest

    i have tried everything to get rid of internet optimizer but your instructions helped so much it is finally off of my computer. thank you.

  • Guest

    Hey, the email address you have on this site goes to a porno search page–oh shame on you shame oh you–what a scam! You use a legitimate excuse to send innocent people to such a site. I am going on my email groups and tell everyone about you. Oh, by the way, my email groups have no less than a 1000 people on each on.

    the web page you have people directed to is:

  • Guest

    I cannot EVER get into one particular link with Yahoo Business Email to change an email forward setting. I ALWAYS get redirected to the internet optimizer site stating that “it” cannot find the link (URL). I have emailed Yahoo about this several times with NO response. I will download the software and see where that puts me.

  • Guest

    I just got this spyware a few days ago and every removal suggestion on the internet doesnt help at all. I will be in your debt forever if you explain how to remove this latest version.

  • Guest

    I think we should start providing company and employee names and addresses and start a lynchin party…

    I predict this will become the 21st century equivilant to “going Postal” of the 20th century.

  • Guest

    ctxpls.exe was also installed with it. And lots of adware.

  • greg

    this is so frustrating, my kids downloaded this crap, thanks i did the crtl alt del, got into process the optimiser.exe , ended this and found Internet optimiser in Programs file deleted this and its gone THANKYOU!

  • the best kept one

    My optimizer stayed on there for about a day, then a little alert box came up that said “this will remove internet explorer from your system. Are you sure you want to do that?” or somthing like that.
    but after that i was able to remove it

    but i found out that it was the yahoo pool cheat from that my brother downlloaded. DONT GO THERE.

    it also infected my compy with 5 other viruses (i manged to remove 4, including internet optimizer)

    but theres still this annoying one called autoupdate that wont go away.

    i hate it when people think its fun to ruin somone elses computer. thats pretty low class.

  • Anton

    It drove me mad but I finally got rid of it by downloading Ad Aware of the net. It is an excellent piece of software that finds all the spyware on your machine and then deletes it for you. The best bit is that the software is free.

  • an anonymous user

    i cant believe, with all my 100s of dollars of virus protection software i still managed to get it 🙁

    oh well, considering all the dodgy sites i go onto…

  • BassPlyr Randy

    If all else fails, start your system in safe mode and then goto C:Program FilesInternet Optimizer and delete the dirty little SOB that way. Was the only way I could get rid of it

  • ST

    Thanks for the tip pete..that optimizer site should be hacked and bought down from the net!

  • peter walsh

    If anyone is having trouble deleting Internet optimizer the first thing to do is to stop the programme from running. In windows XP you can do the three fingered salute (Ctrl Alt Del) and go into task manager. In the application tab you can stop the application running. Then you will have to go to the Processes tab and you will see under the column “Image name” the file ” optimizer.exe. Highlight the file and right click and select “end process”. You should be able to then delete the folder “Internet Optimizer”. Remember to empty the recycling bin.

    If you dont have windows XP facilities I use a nice little programme named Taskinfo2000, which can be found at You simply run the programme and Highlight the file optimizer.exe. and right click and select “end process”. You should be able to then delete the folder “Internet Optimizer”.

  • Tony V

    Like the stupid company really thinks they are going to get hits to their sites, as well as sell any products or services by hijacking your system… This is worse then monopolizing. This is an out right virus to your pc…… But there is nothing you can do about it because we all know where you got it. Probably included in that illegal download you did.

  • HadeS_73

    If justice was for the people it would be hitting yogee instead of p2p , not only it install without my permission , but i can't uninstall it trough stander window uninstall . anybody got a real street addresse for those yogee ..? if you do e-mail me :

  • Guest

    I agree with the comment that the advertising industry and specifically the creators of the spyware should be held fully liable for the damage caused by their creations. They may have a right to pursue their trade and profession. They do not have a right, however, to trespass upon and, effectively convert, others' property, such as a computer or computer network. Thought for the day: I'll bet this could be seen as fraud, or violation of state or federal computer crimes statutes.

  • Guest

    Hi, i guess i was not the only victim of this Internet Optimizer rubish thing lol, i have no idea how it got to my computer but i guess its not me to blame sinse u all had the trouble, i hope ppl who monitor internet will sort this optimiser, i have e-mailed yogeeee company who is linked with the internet optimiser their e-mail is you can e-mail to that person whoever and ask why it always comes up, i said to them to tell me how to get rid of this rubish, hopefully they have strength to reply well take care all.

  • Harley Kelchner

    All software of this nature should be viewed as a direct attack on all personal rights and the developing companys should be held HIGHLY responsible since this software does little other than create major system malfunctions.

    The advertising industry should have THE largest class-action lawsuit brought against it for their blatant missuse of public interests.

  • Brad Swain

    This software is nothing but SPAM. It provides NO useful function and redirects the screen away from the intended URL to a commercially oriented 'error' page when there is no actual error.

  • Advanced user

    The EULA at Internet Optimizer's web site states the software may send all your browsing information back to its controllers. At the time of writing, however, this has not been seen to happen with the current version of the software.
    Can download and execute arbitrary unsigned code from its controlling server, as an update feature.
