My friend, don't rely too much on antivirus software.
If you understand how antivirus software works on your computer,
you'll feel it's no different from a computer virus.
I haven't installed antivirus software in ten years.
I've even disabled Microsoft's.
I spend over 12 hours online every day, but I've never been infected in over a decade.
Instead of trusting antivirus software, understand the file structure and code yourself.
Just the basics will do.
You can then determine for yourself whether a program is safe.
