Method 1:

Uncheck the proxy entry in Internet Explorer.

Method 3:

At this step, we will reset the Windows Hosts file. In fact, this file contains all of the mapping - simply called 'maps', of websites to IP addresses on the Internet, and Windows uses this file to point the browser to the correct address on the Internet. And in the same way, the virus crept and changed the contents of this file, through which users would connect directly to the already prepared malicious addresses. Please edit the Windows Hosts fil file in the following way:

- Click WinKey + R and type % systemroot% System32driversetc in the Run box.
- Rename the hosts file to hosts.bak
- Create a new text file with NotePad with the following content:

# Copyright (c) 1993-1999 Microsoft Corp.
#
# Này là một tập tin HOSTS được dùng bởi Microsoft TCP / IP cho Windows.
#
Tập tin này chứa mappings của IP địa chỉ đến tên tên máy. Each
Số nhập nên được giữ lại ở một dòng này. Cần địa chỉ IP
# được đặt trong theo thứ tự đầu tiên trước theo tên host tương ứng.
# Tên địa chỉ IP và tên máy nên được gỡ bỏ ở ít nhất một
# space.
#
Không thêm được, ý chú ý (như như này) có thể được inserted on nhân
# lines or theo tên máy này được gỡ bỏ bởi một '#' ký hiệu.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

Method 4:

Next, you can use Winsock to 'clean' all Internet connection settings. The program is completely free, easy to use and very effective. Winsock version for Windows XP is downloaded here, but with Windows Vista or Wins 7, please apply the following manually:

- Using Command Prompt (Winkey + R and typing cmd), type the following command:

netsh winsock reset catalog
netsh int ip reset reset.log hit

- Then restart the computer.
