G'oday jandruu, and Welcome to linux.org.
The difference is.....Linux is not windows.
Malware is not really a consideration...providing your browser is reasonably up to date and maintained.
So.....no malware......no alternative to screenwings.
I have not experienced or heard of that type of problem in Linux....i have been running Linux for approx 5 years. Full time...all day every day.
Enjoy the freedom that Linux gives you. Relax.
