Q2: Also is there any free virus protector that can tell me I have a virus after I download a song from LimeWire?

Q3: If I delete un used files like pictures, videos will I get that space back?

Thank you.


Answer:
Well, Yes personal updates are important as they generally are fixes of known bugs and if your using a Windows OS then you should update your computer.

For free anti-virus, I advocate you AVG Free Anti-Virus.
You can get it here –> http://free.avg.com/ww-en/download-avg-anti-virus-free

and yes if you delete un-used files you do get your memory(space) back and I would recommend running a disk deframenter each once in 3-4 months so that it can re-organize your memory.


Answer:
Yes…it is important, some updates are needed to run programs.

I use AVG Free, its great, just make sure you keep it updated.

Yes it will.
