There is a problem with antivirus software and let me say especially the commercial products.
Antivirus software lulls you into a false sense of security – consumers and businesses think that , if I install and have paid for an Antivirus product I will be protected and I can do whatever I want on my computer.
This is wrong. Yes wrong.
Antivirus products can and do have issues and are great at catching 6 month old issues , thats why they fail against stopping zero day infections in most cases and can cause issues with operating systems , including making them non-booting , slowing them down and breaking some aspects.
So what is the solution – you are , its about changing what is between your ears so that you make the correct decision on your Windows computer.
It is about what you do and being careful.
- Keeping your operating system up to date
- Not clicking links in emails
- Watching what you install – software ( the free sort ) , extensions in your browser
- Use an adblocker
- Use Google Chrome
Finally let Microsoft handle your antivirus – Defender if you are on Windows 10 – Security Essentials for Windows 7
