All browsers carry risk when going to questionable sites, especially when you download files (seems you are doing this). From the tutorial I linked earlier:
- If you visit questionable sites, use private sessions (in cognito modes, etc) to reduce what gets saved to your computer or boot from a “live disk” to prevent anything being written to your system. You can also use a “sandbox” to isolate sessions from having direct access to your system (i.e., http://www.sandboxie.com/).
I think we have offered all the help that can be provided for your original question/concern. There is not much we can do to help with what you do on the internet. Good luck, I think you are going to continue to need it.
