Youdontknowwhoiam Virus


Youdontknowwhoiam is an obstructive add-on for your browser that will not stop displaying ads on your screen unless you get rid of the unpleasant app. Youdontknowwhoiam tends to hijack different settings of the browser such as the starting page or the toolbar in order to increase the number of ads it displays.


There are undoubtedly risks related to the presence of the Youdontknowwhoiam virus inside your browser.

The main security concern that most computer users have about their computer systems is keeping them safe from Trojans, Ransomware or other highly dangerous and harmful criminal programs. However, what many do not realize is that it is not necessary for a software piece to be some highly malicious malware piece for it to be a security hazard. Case in point, the browser hijacker apps like Youdontknowwhoiam and Clever Captcha are technically not viruses and their typical purpose differs greatly from the purposes of threats like Spyware, Rootkits, Ransomware Trojans and so on. Instead of trying to harm your system or do something else that’s harmful while in the computer, a hijacker would mostly limit itself to spamming your browser with page-redirects and ads and maybe changing its starting page address or search engine service tool. You can get that on Chrome or Firefox or any other browser really but having a hijacker in your computer won’t necessarily lead to any direct harm. This is because the apps of this category are not typically made with the intention to commit cyber crimes with their help. That being said, though, there are undoubtedly risks related to the presence of Youdontknowwhoiam inside your browser. Sure, at first a software like this may look no different from any other extension you may have in your browser but trust us, as soon as the ads, the banners, the pop-ups, the redirects and the unwelcome changes start to kick in, you will know that something’s not quite right. Most users want to get rid of a hijacker as soon as the effects of its presence become apparent since it can all be a bit too irritating to tolerate. We fully understand that and we are determined to help you deal with a software element named Youdontknowwhoiam which is the newest addition to the hijacker family:

So, how could a hijacker be hazardous?

Though the main goal of apps like Youdontknowwhoiam is to accumulate revenue for the people who’ve created them through invasive online advertising and not much else, you may still get your computer’s safety compromised if you allow such software to operate in your computer instead of uninstalling the annoying app. The hijacker itself will probably not have any harmful abilities of its own. The problem comes from the different ads it may show as those can originate from different sources. For example, a given ad may be coming to you from a site that truly sells quality products. However, some other advert could be a clickbait link to shady sites and pages that may try to trick you or maybe even lad malware inside your computer. Needless to say, it is in your best interest to avoid this second type of ads. However, since it would normally be difficult if not impossible to tell the difference between safe and unsafe ads, it’s simple better to make the generation of invasive and aggressive advertising content on your screen stop and the way to do that is by removing the hijacker software.

    You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

    Type msconfig in the search field and hit enter. A window will pop-up:

    Hold the Start Key and R –  copy + paste the following and click OK:

    notepad %windir%/system32/Drivers/etc/hosts

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    hosts_opt (1)

    If there are suspicious IPs below “Localhost” – write to us in the comments.

    Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

    1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
    2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
    3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.



    • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.

    Right click on the browser’s shortcut —> Properties.
