Security software is essential for any computer. It's the first thing I recommend installing on any new system. You can download free security software here.
Most security software has a weakness, though. It can only stop viruses and other threats once they're on your system and trying to run.
That's why it's important to avoid malicious email links and attachments, and be suspicious of shady downloads. You don't want any viruses getting on your system in the first place.
That's a problem, because lately hackers have been targeting "exploits." These are weaknesses in legitimate software that let hackers slip a virus on your system. This is the danger behind watering hole attacks that can hit you even on popular websites.
You remember the fiasco with Java last year - there were next exploits every other week. A more recent exploit was a Flash vulnerability that went unfixed for days. Unfortunately, no security software deals with this - you just have to wait for an update to close the hole.
Well, until now.
Popular security company Malwarebytes - whose virus remover I recommend often - has released its Anti-Exploit program.
This watches your programs for signs that someone might be trying to use them to sneak on to your system. Then it blocks those attempts. This means it can even stop exploits that no one - aside from hackers - knows about yet.
Malwarebytes won't go into detail about how the software works. However, it says that in the last year of testing - including third-party testing - the program hasn't missed a single major exploit - including the many Java exploits.
The best part is that it's free. The free version shields your browser and any browser add-ons, like Flash. It also covers Java.
If you want, upgrade to the premium version for $25. That adds shielding for PDF readers, Microsoft Office and media players, and you can make your own shields for less popular programs.
