Omiga Plus Browser Infection Removal Guide

For the past one week my PCs have been suffering infection by an application named Omiga Plus. I have no idea how this application get installed on my PC. It infected web browsers and changed their home page and default Search Engine. Omiga Plus has infected all browsers installed on my computer using the technique browser hijacking. Mozilla Firefox, Google Chrome and Internet Explorer start showing Omiga Plus home page when I start. If I type a Search string on the default Search Engine, it is redirected to http://searches.omiga-plus.com/search/ where a lot of pop ups and malicious ads are displayed. While checking their website, this software seems a cool product but it in reality it is nothing but a browser hijacking tool. This tutorial explains the steps to avoid the infection by this Potentially Unwanted Program and procedure to remove Omiga Plus forever.

Check Whether Your PC Is Infected With Omiga Plus

First of all you have to check whether your laptop is infected with this malicious application. All you have to do is to start a browser (Chrome, Internet Explorer, Firefox etc) installed on your laptop and check if you are redirected to a page like below.


Here I have started Mozilla Firefox and suddenly redirected to http://isearch.omiga-plus.com page where a lot of unwanted ads are displayed. If you check the picture show above, the default search engine is changed from Google to their custom search. If you type a query and press enter button, you will see their search results page with a lot of advertisements.

Reason for This Infection

At first I didn't have a clue about the origin of this infection. Omiga Plus is not a virus but it is a Potentially Unwanted Program (PUP) which hijack browsers and leads us to unwanted pages which are filled with tons of ads. By behavior, it can be classified as Adware. This PUP came with a free software installed one week ago by my friend. He doesn't have much IT experience and I believe he forgot to uncheck the check box which offered extra tools where Omiga Plus was listed. So I strongly recommend you to check twice while installing a free software on your computer because malicious products like Omiga Plus may be offered by them.


Remove Omiga Plus Infection

It is a multistage procedure and at first we have to uninstall this application from our computer by using the Programs and Features tool in Control Panel. Once this application is deleted completely, we have to rectify the modifications it made on browser shortcuts. Now let us check each stages carefully.

1: Uninstall Omiga Plus

You can uninstall this program from Control Panel. Follow the steps below to learn how to complete this task.
  1. Go to Control Panel

    You can access Control Panel from Windows Start menu.

  2. Click Programs and Features in icon view (or click uninstall a program in Category view).

  3. Select the application and click Uninstall button on the top


  4. It may ask word verification to proceed


2: How to Recover Browsers

Since Omigaplus infects browser shortcuts, we must right click on shortcuts and delete the extra entry added at target location. Follow the steps below to recover web browsers from Omigaplus infection.
  1. Right click on browser shortcut

  2. click on properties


  3. Check Target

    Now let us check the string shown at target.


    Here I can see a string "C:\Program Files\Internet Explorer\iexplore.exe" http://isearch.omiga-plus.com/?type=sc&ts=1402906043&from=epom2ampuid=SAMSUNGXHD161HJ_S0V3J90Q649140 is shown at target.

  4. Delete Extra String

    We have to delete the extra string after "C:\Program Files\Internet Explorer\iexplore.exe"

  5. Necessary String at Target

    We should repeat the same steps for every browsers installed. Here I am providing you the necessary string you should replace with the infection string at target location.

    • Internet Explorer

      Correct Target string: "C:\Program Files\Internet Explorer\iexplore.exe"

    • Mozilla Firefox

      Correct Target String: "C:\Program Files\Mozilla Firefox\firefox.exe"

Manage Cisco DPC2320 Cable Modem

Cisco DPC2320 is a popular modem supplied by major cable Internet Service Providers. This tutorial explains how to manage this device and configure various features supported by it. It is actually a Wireless Residential Gateway which supports the features of both modem and WiFi router. So, if your Cable broadband service provider supplies DPC2320, you can share the broadband among multiple computers. The same tutorial can be used to configure and troubleshoot EPC2320 Euro DOCSIS Residential Gateway. It has one Ethernet port and WPS setup button. You can connect extra devices using the WiFi.

Internet Speed Hack Trick
  1. Log in

    By default DPC2320 log in IP address is 192.168.0.1 and there is no default password or username.


    You can setup password from the Password Settings under Basic Settings.
    password change

  2. Set time

    If the time zone selected on DOCSIS Residential Gateway is wrong, you can correct it from 'Set Time' link under Setup.


    If the time zone is configured differently, Some cable ISP may prevent you from connecting to their server. If you ever face such a situation with DOCSIS Residential Gateway, you can fix it from the 'Set Time' page.

  3. Backup

    If you ever required to reset the device, you might loose every current modifications you made. So it is recommended to take a backup of the current modem configuration. You can save current Cisco DPC2320 configuration by pressing the link 'Save Configuration to Your PC' under setup.
    • Press Download button to save current configuration

    • You can upload previous configuration from PC using the Choose File button

  4. Check Status

    Click on Status tab on the top menu to view the current status of the device.

    Name Cisco DPC2320
    Modem Serial Number 267900411
    Cable Modem MAC Address 50:39:55:65:9c:8f
    Hardware Version 1.0
    Receive Power Level -1.8 dBmV
    Transmit Power Level 54.7 dBmV

  1. click on Setup

  2. Click on Wireless basic

    Here you can setup the Wireless network name (Service Set Identifier) at SSID. You can also choose the right wireless channel for your network. Changing channel may help you to avoid noises.

Forgot Cisco DPC2320 Modem Password

You don't need to worry if you forgot the password you set for Cisco EPC2320 Euro DOCSIS. Logon to Cisco DPC2320 cable broadband modem using the IP address http://10.1.191.68/. One of the advantage of using this IP address is to bypass the modem login authentication. By typing the IP address 10.1.191.68 on the address bar, you will not be prompted to enter the username or password you have created. So we can say this IP address as the backdoor address to gain control of this model of Cisco Gateway.

Prevent a Device From Joining WiFi

On Cisco DPC2320 you have the facility to block a computer or any device from connecting to the network. You can do it by using the features IP filtering and MAC filtering. IP address filtering works only with devices having a static IP. If they refresh the current IP, most probably those devices will break this filter. MAC address filtering is more efficient because MAC address is inbuilt address. However, there are so many MAC spoofing services which allow users to change the MAC address of their devices. Now let us check how to enable these two filters.
  1. IP Filtering

    Click on 'IP Address Filtering' under advanced setup to block a particular IP from joining the WiFi. You can simply add the IP you want to block and click Apply.


  2. MAC Address Filtering

    Click on 'MAC Address Filtering' under Advanced Setup.


    Here you can either white-list or blacklist MAC id.

    • Block Listed

      If you select block listed, all MAC ids listed here will be blocked from joining the network.

    • Pass Listed

      If you select Pass Listed, all MAC ids entered here are the only devices who can join the network. No devices without specifying their MAC in this filed will not join the network.

Here you can see the basic information about this device. To check the system details, you may look at the chart shown in this page. Here is the details I fetch from this page about this device.

Monitor Connected Devices

Cisco DPC2320 (EPC2320 Euro DOCSIS Residential Gateway) has a special feature which allows us to check the connected devices. Under status bar you can see the list of devices connected to the network with their MAC and IP. You can see the computers connected to this gateway and sharing your Internet under CPE Connections.


Right now two computers are connected to the network and you can see them here.

Issues With Playing Online Games

Since Cisco DPC2320 is a residential gateway, it has inbuilt firewall protection. Cisco DPC2320 may prevent the working of online applications like Online games because those applications use ports which are by default blocked by firewall. If you face troubles with playing online games through this gateway, you might need to perform port forwarding.
  1. Click on Setup tab

  2. Click on Port Forwarding under Advanced settings

  3. Enter the Port number of the application


  4. Click Apply

Point Domain to Hosting in Different Dodaddy Accounts

I have been using GoDaddy for my domain registration and shared hosting for more than three years. So far I am happy with their service and their support tutorials are enough to clear most of the issues or doubts. However, yesterday only I found a new issue with hosting one of the domain name I purchased through them. Though both the domain name and hosting are from them, they are in different accounts. I purchased the domain name from a GoDaddy account but the hosting is from a different account. Now the trouble begins, I couldn't point the domain to hosting account because both are not in same account. I have added the domain name to hosting and created a secondary folder for it but after uploading content, it says your website cannot be displayed. So here I am going to present the steps I have done (which are necessary even if you bought web host and web address from same account) to fix the issue.

Complete Guide to Publish a Website With GoDaddy

This tutorial explains the entire procedure to publish a website with GoDaddy.  I have divided the guide in to two. First part explains how to configure URL address to the uploaded website when you bought both host server and web address from same account. Second part of the guide explains how to complete the procedure if you bought both of them as different users.


1. Domain Name and Host are in Same User Account

Here you have both host server space and web address in the same account. It is the easiest way to upload and configure a website because all we have to do is to create a sub folder and point the website address to it. Once the folder is activated, we can upload files to it either using file manager or using ftp. The detailed steps are given below.
  1. Logon

    Visit http://www.godaddy.com and click sign in. Now you should enter the username (or customer id) and the password.

  2. Manage Host

    Click on Hosting tab on the top of the window. Sometimes you may need to click on either manage or setup button.
    information

    • If it is your first time, you will see setup button. Then you will be redirected a page where you must add a primary domain.

    • If you have already using it, you may need to click on more to get hosted domains window.

  3. Click on Add Domain
    add

  4. Adding address

    Here you must create a folder to host  new one after entering the domain name. You can use browse button to select a folder if one exists or you can create a new folder.
    folder

    After selecting the folder, click OK. If the both products are purchased as same user, you can directly upload the website content to the new folder using either file manager or using FTP software.


As I said before, if the web address and host are in the same GoDaddy account, you do not need to do any more steps. You can directly upload the website to the folder you have created. But it won't work if host and web address are in different GoDaddy accounts. Here we need to point the site URL to the host server IP address. The below section cover this part.

2. Domain Name and Host Server are in Two Different User IDs

Here you have purchased both products as different users. One of the common scenarios is to publish a site as a web development company but the web URL belongs to the client.
  1. Logon to web host

  2. Click on Hosting
    information

  3. Look under server details for IP address
    IP to store

  4. Now login to the GoDaddy account where you bought domain. Click domain tab on the top of the window.
    uploaded website not showing


  5. click on Launch button
    launch

  6. Now click the one which you want to point to the hosting in another account.
    show site online with two different

  7. Click on DNS Zone File tab
    edit DNS

    Click on edit button under Actions.

  8. Edit Zone Record

    zone record
    Now we must enter the IP address of the web host server under Point to: and then click on finish button. Now we need to wait for few minutes (sometimes it may take hours) to show the website uploaded to host server by typing the web address on the address bar of browser.
