STEP 2 : Check Windows HOSTS file
The hosts file is one of several system facilities to assist in addressing network nodes in a computer network. It is a common part in an operating system's Internet Protocol (IP) implementation, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, that identify and locate a host in an IP network.
Because of its role in local name resolution, the hosts file represents an attack vector for malicious software. The file may be hijacked, for example, by adware, computer viruses, trojan horse software, and may be modified to redirect traffic from the intended destination to sites hosting content that may be offensive or intrusive to the user or the user’s computer system.

1. Go to > C:\WINDOWS\system32\drivers\etc.
   
   
2. Double-click “hosts” file to open it. Choose to open with Notepad.
   
   
3. The “hosts” file should look the same as in the image below. There should be only one line: 127.0.0.1 localhost in Windows XP and 127.0.0.1 localhost ::1 in Windows Vista/7. If there are more, then remove them and save changes.
   Windows XP :
   
   
   
   Windows Vista and 7 :
   
   
   
   You can find more details on how to reset your host file here.

How can I prevent these infections?

A. Prevent malware with smart online behavior

The single biggest factor in preventing a malware infection on your PC is you. You don't need expert knowledge or special training. You just need vigilance to avoid downloading and installing anything you do not understand or trust, no matter how tempting, from the following sources:

From a website: The internet is a dangerous place so try to stay away from sites offering commercial software serial numbers, keygens or other hacked material.
Download programs only from reputable websites that have confirmed the software is malware free.If you are unsure, leave the site and research the software you are being asked to install. If it is OK, you can always come back to site and install it. If it is not OK, you will avoid a malware headache.

From e-mail: If you're not familiar with the sender, do not open, download, or execute any files or email attachments. Some viruses replicate themselves and spread via email. Stay on the safe side and confirm that the attachment was sent from a trusted source before you open it.

From physical media: Your friends, family, and associates may unknowingly give you a disc or flash drive with an infected file on it. Don't blindly accept these files; scan them with security software. If you are still unsure, do not accept the files.

From a pop-up window: Some pop-up windows or boxes will attempt to corner you into downloading software or accepting a free "system scan" of some type. Often these pop-ups will employ scare tactics to make you believe you need what they are offering in order to be safe. Close the pop-up without clicking anything inside it (including the X in the corner). Close the window via Windows Task Manager (press Ctrl-Alt-Delete).

From another piece of software: Often, a software installer includes optional installs, such as a toolbar or other programs. Be very careful what you agree to install. Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.

From illegal file-sharing services: You're on your own if you enter this realm. There is little quality control in the world of illegal software, and it is easy for an attacker to name a piece of malware after a popular movie, album, or program to tempt you into downloading it.

B. Prevent malware with the right software

1. Keep your Operating System, Software, and Drivers Up-To-Date

It is essential that you keep your operating system, software, and drivers updated with the latest hotfixes, patches, and security releases from the manufacturer on a regular basis.
Make sure that the Windows Updates are turned on and that you have the latest security releases and patches for your operating system.
Let Windows automatically check for security updates. Windows 7 is using this setting out of the box - just make sure it's really turned on.
Cybercriminals are increasingly targeting home users. Their entry points are vulnerabilities (certain code errors or bugs) in popular third party (non-Microsoft) programs, which are exploited and used as a gateway to compromise PCs and access confidential data such as passwords, online profiles, and bank details.The only way to prevent these types of attacks is to apply security updates, or “patches” which are offered free-of-charge by most software vendors.

2. Build up your malware defenses

The Internet is not a safe place if you go online without securing your computer, in order to avoid any malware infection is important that build up a solid malware defense system.
This is a list of components that should be part of your security configuration :

1. Antivirus Engine
2. Firewall
3. Behavior Blocker
4. Host Intrusion Prevention System
5. Virtualization Software
6. Site Advisor
7. On-demand Scanners

You can build up your malware defenses with our help by starting a thread in our Security Configuration Wizard forum.

3. Secure your browser

• Consider the use of an alternate Browser, such as Firefox, Google Chrome, or Opera, which are not susceptible to the same vulnerabilites of Internet Explorer 7 and 8 or update your Internet Explorer to the latest version.
• Disable unnecessary plug-ins in your web browser. This will help keep you safe from malicious scripts and activeX exploits
• Use available add-ons to improve it's general security.
• Take advantage of your browser's pop-up blocking, download screening, and automatic update features.

You can start a thread in our Security Configuration Wizard forum and we will help you secure your browser.

4. Back up all of your data
Because your information could be lost or compromised , make regular backups of your information so that you still have clean, complete copies .
Back up all your important documents, personal data files, photos to a CD or DVD drive, not a flash drive or external hard drive as they may become compromised in the process. The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, .htm, .html, .xml ) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executables inside them as some types of malware can penetrate compressed files and infect the .exe files within them.
Determining how often to back up your data is a personal decision. If you are constantly adding or changing data, you may find weekly backups to be the best alternative; if your content rarely changes, you may decide that your backups do not need to be as frequent. You don't need to back up software that you own on CD-ROM or DVD-ROM—you can reinstall the software from the original media if necessary.

5. Use a Limited/Standard User Account (LUA)

With Windows 7 working as a standard user has become more convenient than ever. There's no reason not to work with restricted permissions, what makes a giant leap in your computer's safety. The way Microsoft found to keep security, comfort and function in balance by integrating User Account Control (UAC) that seamlessly, is one of the benefits Windows 7 offers.When using a Limited/Standard User Account , your user profile might still getting compromised, but not Windows 7 basic operating system in the background. Even your profile got hit, all your pictures, MP3 files or documents can be restored easily by logging in to another account that is not yet compromised.

• To change your account type go to : Start -> Control Panel -> User Accounts and Family Safety -> User Accounts -> Change your account type
• To create a new Limited/Standard User Account : Start > Control Panel > User Accounts and Family Safety > User Accounts > Manage Accounts > Crate New Account
