Even the most cautious Internet users eventually get their PCs infected with Malware. Malware infections are more common than ever, especially on PCs still running Windows XP with inadequate anti-virus protection. Malware authors are getting craftier to trick an unsuspecting user into downloading malicious software by disguising it as a helpful advertisement or download. How can Malware be removed from a computer once it has infected it?
Assess the Loss
Examining the extent of the damage to your PC is the first order of business. A definition, please. First, you should check if Windows can still load on the PC. This has the potential to alter events. Getting Windows to load onto a PC that won’t boot is an obvious first step.
This post focuses on a scenario where Windows will load. We can ensure that the boot sector and other system files are not hopelessly broken if accurate.
The First Steps
Malware infections can cause strange window backgrounds, intrusive pop-ups, and other symptoms. After logging back in, you can tell if Malware was installed on your computer. Many alert you that your computer is infected with malware or Malware and ask for your personal information and credit card number so they can charge you for removing the threat. Don’t be fooled!
Obtaining the proper tools to examine the computer and fix the Malware infection is a necessary first step. If you have administrative privileges on the machine, the following files should be copied to a USB device. They can be found for nothing on the internet and downloaded immediately.
Authorized Automatic Start-Ups
Invoking Process Explorer
Anti-Malware by Malwarebytes
Keeping the Power On
After transferring the contents to the USB drive, you may launch “autoruns.exe” from the extracted folder by plugging the drive into your computer.
While standard startup editing tools like Windows’ in-built “msconfig” can show you what programs and registry items are being loaded at boot time, Autoruns shows you everything.
The ability to inspect code signatures is one of the most valuable features of autoruns. You can check that the software is what it claims to be using the code signatures. The digital fingerprint confirms the authenticity.
Malware rarely passes the code signatures test since they are fake.
In addition to its other benefits, Autoruns lets you conceal legitimate Microsoft and Windows entries so that you don’t have to inspect them for anomalies manually.
If you see anything dubious, such as an item with no description or a questionable code signature, uncheck it.
Using the Process above Explorer tool, you can determine which service or process is responsible for the Malware-related pop-up windows on your desktop. This might be a massive assistance in pinpointing the source and nature of the malware infection.
After removing potentially malicious startup items and processes, you may install the Malwarebytes Anti-Malware tool and perform a complete system scan to identify and remove malware. You need to update the signatures first, as these are the first to go through frequent changes and updates. When performing a comprehensive system scan, you’ll want the utility to be as efficient as possible, and the most up-to-date signatures allow for just that.
Some malware is expert at thwarting your attempts to remove it from your system. Even more so, they actively seek out programs that use commonly recognized anti-malware executables and prevent them from running. Renaming the installer’s executable can help if you’re having trouble installing Malwarebytes. The.exe filename extension may need to be changed to the.bat filename extension. This will not prevent the software from installing; it will ensure that malware will not prevent the program from operating.
Even when the software is set up, this is a possibility. To make the application files executable, you may need to rename and alter the extension.
You can trust Malwarebytes to detect any malware on your computer. After the cleanup, you will likely need to restart the system. After restarting, check whether you still see any suspicious pop-ups or have any other malicious software installed. Now is also an excellent time to run a comprehensive system scan using your preferred virus scan software.
Virus detection software is a common target for malware attacks; if yours is seriously outdated or compromised, you may need to reinstall it.
Fix Completed
If you were lucky enough to have your system freed from a severe malware infestation with the help of the utilities above, please take this opportunity to strengthen your defenses against future attacks. Ensure you have the most recent security patches installed, especially if using Windows XP Service Pack 3. Internet Explorer 7 is the very minimum. However, Internet Explorer 8 is preferable because of its additional security features.
Check that your virus protection is up and running smoothly. These tools are rendered useless if they are using out-of-date viral signatures. Installing no virus scan is about the same risk as having one with out-of-date signatures.
Many high-quality virus protection programs are offered without cost. Antivirus software like Avast and AVG, among others, provide excellent protection at no cost to home customers. All that’s required of you is to register for the program and use the key emailed to you to activate it.
Keeping an up-to-date copy of McAfee, Symantec, or other more expensive virus scan products is a pain and an unnecessary expense if you use one of the aforementioned free alternatives.
Online Behavior
You still need to be cautious and keep close tabs on your browsing habits nowadays, no matter how well-protected your machine is with software solutions. When you download and install plenty of free trials and P2P applications, you significantly increase your system’s vulnerability to infection from Malware.
Do not download software that appears to be from an unknown source on any website you visit. Don’t get duped by a window that claims your computer is infected and will remain so unless you buy and install their software. Malware authors utilize these tricks to infect tens of thousands of computers worldwide. Choose your links and websites carefully. Using a web filter, such as the free program Untangle, can also dramatically improve your online safety.
Malware is here to stay, and as a result, the dangers it poses to computer users, both at home and in the workplace, will only increase. Malware can be avoided entirely with the correct tools and by employing multiple levels of protection.
