This is not a bad solution if you take a few precautions, such as not having internet access on your PC.

but I don't know how safe

It will be as safe as you make it in terms of computer security (OS, internet access, passwords, etc.).

it is maybe I should just switch to Linux becaus it's windows ,

That would be a good solution, since you mentioned it, I think you should first learn more about the new OS (settings, management).

the Pc is around 2GB Ram I don't think I can upgrade

Technically, this may have limitations, but even so, you can get a slightly more modern PC for very little money. If you have money to invest, then finding it to upgrade your PC should not be a problem.

that don't know if it will work for Linux

It will, because there are Linux distributions that are not demanding on the PC power, created specifically for weak (old) devices.
