but, of the posts I have read, I agree with
[]D[][]V[][]D and definitely with the idea of (I think it is fletch who said it) getting rid of limewire. Solid advice on both, and well informed. (+ rep, on both)
If you are going to be downloading shit illegally, use torrents. Also, download and install PeerGuardian2 (It's not perfect, but it not only blocks ips, but has them categorized into what type of ip it is, like Gov't, spyware, etc. (again, it's not perfect, but it can potentially help. You can also run peer guardian when you are browsing sites you want to feel more secure about, and it will blink when something that you want blocked is being blocked. You may run into stuff that is perfectly innocent being blocked, but that is far better for your peace of mind than not knowing what is going on.
I also suggest malwarebytes anti malware. It runs only when you want it to, and can find and remove all sorts of baad stuff.
I think you are also probably not being watched by LEO, but maybe are being spied on by spyware.
You may also want to change you anti virus to Avast, which has an option for boot time scan, which gets things before they load into windows. (Virii and malware are harder to remove, and in some cases, even to detect, once windows is up and running)
So, in short, do a little research on p2p (peer to peer) security, and general computer security, and you will be able to rest easier. The more you learn about that stuff, the more you can relax. (of course, it's no substitute for common sense)
If you are wondering how the fuck I know what I am talking about (A valid question, and one you should always ask of anyone giving advice...if they get pissed, then their ego is getting involved, and that makes them less likely to be able to give unclouded advice), if you are under 20 years old, then I have been working with and on computers longer than you have been alive.
Actually, if you saw the monstrosities that I started out on, you might not consider them computers at all...big drums full of magnetic tape with far less storage capacity than your cell phone, for instance.
and theres my 2 cents.
