applications? ie. Java ire, Java runtime and so on? My security system
made me remove all Java from my PC.
Everything Java is not infected.
I know that reading all the dire warnings you might see every
day might make it seem like just turning on your computer is an
exercise in dangerous futility, but it’s just not that bad. With a
little caution on your part (and perhaps a better security system), you
can use the internet, including Java, quite safely.

I want to address a statement you made in your question: “My
security system made me remove all Java from my PC.” My initial
reaction? That’s just wrong. I don’t know exactly what security system
you’re running, or what it saw that it decided to have you take that
action, or if perhaps there was a misunderstanding, but removing Java
from your system is not a viable solution.
Java, like any technology on your computer, can be used safely and
to great effect. It can also be abused and infected, of course, but
removing it is rarely the answer. Reinstalling it perhaps – or in the
worst case reinstalling your entire operating system, but the net
result is that you can have a safe system running Java.
So I can’t really comment on how you got to where you are, since
details are not included.
be used safely and to great effect.”
But I can recommend on how to proceed, and it’s mostly the standard
safety to-do list that I’ve talked about several times.
Start with a clean system. If I had to hazard a
guess, your security software did detect an infection and attempted to
remove it. If that’s the case, the “right” thing to do is to reinstall
the software. Perhaps even reinstall Windows itself to remove all
traces of the infection.
Keep the System Up-To-Date. Turn on Windows
automatic updates. Java, itself, has an automatic updater that you
should let run, and should allow to update when needed. Essentially, you
need to make sure that all the software on your machine is as
up-to-date as possible. Why? Because all software vendors are fixing
bugs that could be exploited to infect your system with malware. Installing
the updates removes those vulnerabilities.
Get behind a firewall. I don’t really care if it’s
a router or a software firewall, or even if all you do is turn on the
Windows firewall, just do something. (OK, I do prefer a router, if that
works in your scenario.) A firewall is an important first step in
protecting your system from an entire class of malware.
Get better security software. Like I said, I don’t
know what you’re running or what it told you to do what it did. It
sounds like you’re running a suite, and I have to say that I
really don’t believe in all-in-one security suites – I just
keep hearing that they cause more problems than they’re worth. I would
get a separate anti-virus product and an anti-spyware product, make
sure that they are up to date, and make sure that the databases that
they use are also being updated regularly.
Those are the biggies. I have more on the subject in Internet
Safety: How do I keep my computer safe on the internet? – I
strongly recommend you read that as well.
The bottom line is that there’s no reason you can’t pull together a
system that will allow you to browse and use the internet – including
Java based technologies – safely. It just takes a little preparation
