Now it's time to give you some tips, tricks, advice and recommendations on how to protect your system and prevent you from being infected in the future. This is where I'll explain basic security measures that you should take to protect and harden your system, and also make sure it stays as safe and secure as possible against hackers and malware. You are free to ignore the recommendations listed below, although I obviously do not recommend it. If you have any questions about one of the points covered in the speech below, feel free to ask me your questions here directly so I can answer them and guide you.Windows Updates
Keeping Windows up to date is one of the first steps in having a safe and secure system. The Security Updates that Windows receives are meant to fix exploits and flaws in it that makes it more secure and not exploitable by hackers. In order to do that, you should always install the Security Updates, known as "Important Updates" on your Windows system. These updates are released on the second Tuesday of every month, but some are also released before if they are emergency/critical Security Updates. Let's make sure that you have all your Important Updates and Recommended Updates installed and that your Windows Updates are set to be installed automatically.Keeping your programs up-to-date
Like keeping Windows updated, keeping your installed programs up-to-date is another important step in having a safe and secure system. Outdated programs can be exploited by hackers and malware to infect a system and take it over. This is especially true today with the rise of Exploit Kits
which is one of the biggest attack vectors to distribute malware. Therefore, you should always keep vulnerable programs like Adobe Flash Player, Adobe Shockwave Player, Java, Silverlight, etc. updated to their most recent version (even better, you don't have to install them if you don't use them). Programs like SecuniaPSI
and Heimdal Free
will scan your system for outdated programs, and help you identify them, as well as update them.Antivirus, Antimalware, Firewall and Anti-Exploit/Ransomware
Having a decent security setup (led by an Antivirus) is the most crucial step to protect a system. These programs are a layer of defence that will prevent a system from being infected, or if it somehow ends up infected, help mitigate the infection and remediate it. Ideally, you should have on your system one Antivirus (never more than one installed at the time), one Antimalware (you can install multiple of these, assuming they do not conflict with each other and the other security programs installed), one Firewall and if you wish, one Anti-Exploit and/or Anti-Ransomware (since Ransomware are currently the most dangerous threat around and it can hit anywhere). Here are a few programs worth checking out if you don't have one yet.Note: The programs listed below are all free to use or they have some sort of trial. Some of them have a paid version that provides more features, while a lot of other good programs only have a paid version but aren't listed there (such as Kaspersky and ESET Antivirus products).AntivirusAntimalwareFirewall
Starting in Windows Vista, the Windows Firewall greatly improved and will satisfy the needs of most users. If you do not have an Internet Suite Antivirus program (which includes a firewall) and you want to use a 3rd party firewall, you can consider the options below.
Anti-Exploit/Anti-RansomwareWeb Browsers and Web Browsing
- GlassWire - Has both a free and paid version (with different packages);
- Windows Firewall Control - Gives you more control over your Windows Firewall;
- TinyWall - Lightweight firewall implementing the Windows Firewall and giving you more control over it;
Web Browsers could be considered as the closest door between a malware and your system. This is where most malware goes through to infect a system, and therefore it should be the program(s) you want to secure the most. There are two ways of going about it: hardening your web browser via extensions, and having good browsing habits.
Hardening your web browser means to install extensions that will help it protect itself (and your system on the same occasion) against Exploit Kits, MiTM attacks, etc. but also you at the same time. Here are a few extensions that I recommend you to install.
- uBlock Origin: Efficient multi-purpose blocker that is lightweight on RAM and CPU usage (Google Chrome and Mozilla Firefox, called uBlock on Opera);
- HTTPS Everywhere: Extension that converts your HTTP (unencrypted) requests to HTTPS (encrypted) ones (Google Chrome, Mozilla Firefox and Opera);
- Web of Trust: Website reputation, rating and review extension that will help you quickly identify bad and suspicious sites from good ones (every web browsers);
- uMatrix: For advanced users, a point and click matrix-like extensions that allow you to control requests done on a webpage (based on source, destination and type) (Google Chrome, Mozilla Firefox and Opera);
- LastPass: Secure password manager allowing you to create, manage, and use passwords you save in your LastPass account (every web browser);
As for safe browsing habits, you can find tons of guides, tutorials, articles, etc. online that will highlight the basics you need to follow (only visit websites you trust, do not click on ads, do not download files from untrusted sources, use a password manager, always verify the URL of a website and make sure it's correctly typed, etc.), and even what you can do if you want to take it a step further (create a fake email address for spam emails, browse the web in a privacy mode, etc.). Here are a few:
As you can see, there are plenty of resources out there. Simply Googling "good browsing habits" or "safe browsing habits" should allow you to find a lot of them.Other recommendations
Even if you follow every recommendation that I listed here, in the end, it's also your job to be careful when browsing the web and downloading files if you don't want to get infected. Therefore, if you use your brain (common sense) when browsing the web, downloading programs and files, etc., you have far less chances to get infected by a malware. If for example you're not sure if a website is legitimate or not, or if a file is safe to download and execute, or if a program looks "too good" to be free, I suggest you to avoid going to that website, downloading that file or using that program.
Here are a few guides, tutorials, articles, etc. that you could read in order to learn more about computer protection and security to improve your current computer protection setup but also improve your good web browsing and computer usage practices :The End!
And that's it! Now that you know more about how to protect your computer and secure it, you're good to go back to your online activities, but in a safe and secure way! You are also free to stay on BleepingComputer and ask for help in different topics if you ever need to. Just make sure that you post your question/issue in the right section to get the best assistance possible. And if you ever get infected again (which I hope you wont!), you can always comeback in this section to get another checkup with one of our trained malware removal member.
