How to remove malware from your computer?
Remove malware, remove viruses

The simple truth about malware removal is that it must be conducted with antivirus software. But before starting the scanning, it is important to suspend the malware activity. Viruses keep getting stronger, and the most developed ones can counteract you in your attempts to remove them.

Why do I need to stop the viruses?

Malware developers are doing their best to make their “product” more effective and sustainable. At the beginning of the ‘10s, almost all malware had a low ability to prevent its removal. The only virus that could do so was so-called Winlocker – the predecessor of ransomware. That malware did that in a pretty rude manner – just blocking all system functions and demonstrating to you the scary banner with ransom payment instructions. By the way, some of the ransomware variants, especially ones that can infect the UEFI/BIOS, are doing the same thing nowadays.

Disabled Windows Defender

That’s how the window of Windows Defender looks after the malware attack.

However, the viruses which must stay stealthy to conduct their activity use other tactics. Spyware and stealers adjust the system settings in a particular way, so you cannot use your anti-malware software anymore. Even if you are not using the Microsoft Defender, known for its vulnerabilities and possibility of stopping through the Group Policies, malware can still manage to stop the third-party antivirus programs from running.

Initial step: reboot your PC into Safe Mode

A lot of malware of different classes carry several additional programs in their package. They may be 100% legit, but in that case, they are used for malevolent purposes. Different apps like CCleaner may be used by crooks after the malware injection to remove your antivirus. And until you have your Windows running in Safe Mode, malware can remove not only present antivirus but also ones that you will install after the virus injection. Could you not give it a chance!

Safe Mode in Windows 10 can be turned on through the following steps. Press the Start button→ Power, hold the Shift key on your keyboard and press the Reboot option. Your computer will show you the boot menu, where you need to choose the “Boot the system in the Safe Mode” option. There are several options there – the most optimal is Safe Mode with Networking. This will allow you to connect to the Internet and download the anti-malware software.

Step 2. Install GridinSoft Anti-Malware

GridinSoft Anti-Malware provides high-rated security features that will help you remove any virus and restore the system after the attack. Besides the malware removal abilities, this security tool can also offer you the function to reset your browser settings in just several clicks – without opening each browser and looking for the browser reset button.

After the GridinSoft Anti-Malware installation, you will see the offer to activate a 6-day free trial. During the free trial, the program has its full functionality, so you will surely remove all viruses from your computer. Just specify your email, and you will get a free trial key on it.

Now, when the computer is cleaned of viruses, it’s time to deal with the consequences of malware activity in your web browser.

Step 3. Reset your web browser

Web browsers in particular, and all networking generally, is one of the most damaged system elements during the malware attack. Viruses aim at your networking configurations to provide themselves access to their servers. If you don’t remove these changes, there is a high chance that you will suffer from random network errors or other unwanted issues.

You can do this step manually, as well as with the use of GridinSoft Anti-Malware. The last option is better, in my opinion, since you can reset all web browsers in just three clicks.

The HOSTS file is a system configuration file that manages the DNS routing. Malware changes it for its purposes: to reroute your queue or to show you the phishing site instead of a legit one. Reverting it to the original settings is very important if you want to have your system working well. The following reset guide repeats the official Microsoft guide for HOSTS file reset.

Create a text file named “hosts” on your PC’s desktop, then open it and fill it with the following lines:

# Copyright (c) 1993-2006 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a ‘#’ symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handle within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

Find the hosts.txt file in C:/Windows/System32/drivers/etc directory. Rename this file to “hosts.old.txt” (to distinguish it from the new one), and then move the file you created on the desktop to this folder. Remove the hosts.old from this folder. Now you have your hosts file as good as new.
