Basic Line Of Defense :

  1. Most Antivirus companies have come up with their internet security suites over antivirus which is the need right now. You must have one from reputed providers in the industry such as Kaspersky, Eset, Symantec etc. Remember “cheap” always isn’t good. The product which claims to give you 100% protection is misleading you.
  2. Whether you use Windows/Mac or any Linux based distribution you must have it updated with latest security pateches applied. Leaving it outdated just to save time or bandwidth might cost you heavily one day. Recent example is WannaCry Ransomware.
  3. Have a firewall installed , anti viruses these days have one built in and they are better than the default of Windows.
  4. Stop opening emails from unknown sources serving you with attachments intended to not only Spam but to make things like ransomware attacks happen.

Defense : Level 2 to Avoid Viruses on a Computer

  1. Scan your computer for viruses, malware everyday/weekly by scheduling it into your security product.
  2. Just don’t plug n play USB drives without scanning it properly.
  3. Stop downloading and going for the free tag over the internet when it comes to softwares. Most of them come bundled adwares, popups, malwares, nasty toolbars, weird browser extensions that will not only slow down your computer by creating unccessary unelevated tasks but might steal your data by circumventing it to some far off servers. Use licensed software.
  4. Look for “https://” tag when browsing a website. These websites are encrypted and usually safe. But don’t be mistaken. Sites which spread piracy and illicit content use them too these days by faking https certificates. Be vigilant and trust your gut.
  5. Install Ublock Origin, Ghostery, Https Everywhere, Privacy Badger extensions for Chrome/Firefox to block most of the popups and malicious ads that popup frequently. Review your browser settings and do not let them access microphone, camera etc without permission.
  6. Always check the file extension of a file you’re about to open after downloading from the internet. A .mp3 file having a .exe extension means you’re on the wrong boat.
  7. Disable Macros in MS-Excel.
  8. Use tools like Ccleaner to clean your computer and running them efficiently.
  9. Linux users do not use sudo-apt commands for downloading content from unverified sources. Proceed with caution when given root privileges.
  10. Windows users should check the startup tab in task manager and disable any program which doesn’t seem right. Do review the app permissions.
  11. Always create system restore points so that you may restore your system from crashes and failures.

Defense : Level Advanced to Avoid Viruses on a Computer

  1. Encrypt your entire computer right away at least (AES256 with SHA512) . Windows users : BitLocker, Veracrypt etc. Linux users can encrypt their entire partition at time of installation itself!
  2. Install “KeyScrambler” if on Windows which encrypts every keystroke from your keyboard protecting you from keyloggers.
  3. Use a Password Manager like Lastpass/Dashlane. Get a reputed VPN like PIA, NordVPN, ExpressVPN, F-Secure Freedom etc. Free ones transport your data to places you couldn’t imagine. (No Disneyland!)
  4. Use Two Factor Authentication everywhere you can.
  5. Have regular backups on external HDD and encrypt them too. Just remember the password.
  6. Mac users generally have a perception that they are full proof safe from attacks and such things from the windows ecosystem but they are highly mistaken. One bad day and your fantasy of safety will end. Have security products installed on Mac and Linux both no matter what others say. Nothing is safe in the connected world.
  7. Disable USB access, Cover your webcam, Remove flash and other insecure products with a lot of vulnerabilities like Java etc or keep them updated at least.
  8. Disable SMB and Telnet Services in Windows in Add/Remove Features option.
  9. Check your hosts file in Windows for any unidentified website and delete them. Hosts file is locates in : C:/Windows/System32/drivers/etc/hosts. Open it with notepad and do the intended.
  10. Never store financial information or documents of self without having proper protection or be a victim of identity theft. Save them in encrypted folders if needed.

Lastly , I would say that no mistake is bigger than human ignorance and doittomorrow thing. Take these steps and you’ll be one step closer to a safer cyber tomorrow.

Stay updated on the developments in cyber space, share with your parents, children, friends and anyone else you care about on how to stay safe ONLINE.
