Dear reader it seems you are looking for ways to deal with the problem named Mysites123. You have come to the right place, in this article we are not only going to provide extensive instructions how to remove Mysites123 from your system, we will also provide valuable information how to avoid further problems caused by the software in question.

We will be upfront about this – you are most likely dealing with a program of the Adware class of Malware. This is a sub-type of a virus class known for instigating a number of unwanted pop-up Advertisements and Website redirects onto the affected users’ desktops.

 The mysites123 Virus

In addition to this you may notice some strange changes to your browser like toolbars appearing without your knowledge or consent, text turned into hyperlinks leading to some unsavory places and in some documented cases even a complete replacement of the web browser.

Some general advice for you:

  • Do not click on the ads whether they are in the form of a pop-up window or a banner, it doesn’t matter. Avoid interacting with them.
  • Once you are redirected to some strange website because of the virus, leave as fast as you can. Nothing good will come from spending time on such a shady place.

How did the virus reach your device?

There are a number of ways in which the malware may have infected your system. One of the oldest tricks in the book but still popular and ever evolving is through e-mail attachments. A lost has been written on this subject but still a couple of suggestions for you to follow:

  • Be especially careful when opening an e-mail from someone you have no prior history of emailing. Be even more careful when clicking to download an e-mail attachment. In fact we strongly advise against doing so when dealing with e-mails from senders you don’t know.
  • Open your eyes wide, there are things like the notorious phishing scam e-mails, messages that look like a legitimate sender has tried to contact you but are in fact bogus mails looking to steal your personal information.

Another way Mysites123 may have found its way into your PC is if you have downloaded and opened an infected executable (.exe) file from a file sharing website or a torrent. You can never be sure whether a file is not messed around it so if possible always use an anti-virus/anti-malware scanner to check a file before installing it.

The most common cause by a landslide is through software bundles. That is the Adware software was attached and installed together with another program, most likely freeware that you have installed at some point in the past. The reason you have probably missed it in the first place is very few people actually read through the EULA’s or review the Advanced options before actually committing to the installation process. Our advice for you is to do just that – click on advanced installation options and double check if something else is not been installed together with the actual thing you want to install.

  • Delete all of them. I’ve encountered this several times in the past 2 weeks. They are a 100% part of the virus. Just delete them from your hosts file and close/save it. 🙂 Tell me if that helped later 🙂 I’m here to help.

  • Removing the text does not guarantee Mysites123 will not come back again.You need to finish up the rest of the guide for everything to be completely effective.

  • Hello Sayma,

    This one is indeed very strange, because in my experience SpyHunter4 is really the best for this. If you have paid for it you can contact the technicians there to access your computer remotely.

    There are two more things that you can do yourself.

    1. Go to Network Connections, select your internet adapter, select properties and open the IP4 line. After you do it look for the DNS line. If it has any numbers in it set them all to zeroes or click to obtain them automatically.

    2. In Chrome open the settings and look for Users. Use the create new user button to create a new user, then delete the old one you were using. Also, again in settings, select the Manage Search Engines and remove MySite123 (or other suspicious search engines) from there.

    It may be entirely possible that Mysites123 is already removed from your PC and you only need to adjust back the settings that it changed.

    Please, let me know if these work for you and specifically which one fixed your problem.
