Answer 1

You will need a antivirus, antispyware and firewall. Here's my recommendation based on experience:
Firewall

Antivirus
http://www.free-av.com
Antispyware
http://www.microsoft.com/athome/security/spyware/software/default.mspx
http://www.javacoolsoftware.com/sbdownload.html
http://www.spybot.com/en/spybotsd/index.html

You can have more than one anti-spyware apps install on your pc but you need to have only one antivirus or firewall running at a time to prevent system conflicts.

Answer 2

On your Desktop PC, try using a Personal Firewall also. This will block hackers and others from attempting to gain unauthorised access to your computer, while you are on the internet.

A good one, that offers a FREE version is ZONEALARM... You can find it here... http://www.zonelabs.com/store/content/home.jsp

You have sort of answered your own question " it never happens on my mac but on my desktop pc..... "

We pay millions to microsoft, to use Windoze on your computers, and still put up with them crashing / locking up / rebooting / blue screening all the time.....

Why do you think it is always being attacked by viruses and malicious software??... because it is also the most insecure operating system available!.... just connecting to the internet with a Windows computer is risking your privacy!

Alternatives (which are also miles cheaper) include - Linux / Macintosh etc.

Answer 3

I can give a few links that offer free virus and spyware removers...!You may be having a virus or spyware installed on your PC. Norton, AVG , Avast are free antivirus software. Ad-aware, Ewido are free spyware removers. You can download free softwares at

What Is a Computer Virus

Computer viruses are actually small programs that have the ability to replicate themselves and then spread throughout your system in many ways. This is usually done without a user’s knowledge. Such programs may copy themselves to a shared network resources or mail themselves to E-Mail Contacts that are stored in your address book.

After a Virus has infected your system, it will usually trigger itself in some sort of fashion. It can launch annoying pop up windows that repeatedly place messages on your screen. It can deny you access to your data files and even change your system configuration settings. In advanced stages of infection, a virus can cause major damage to your system as it can corrupt your files and render them unreadable. It can even start deleting files as well. A virus doesn’t always have to trigger itself upon infection. It can actually be programmed to launch at a specific time or on a specific date so that there will be no obvious sign of system infection. A virus will usually disguise itself and may even attach itself to another file, so as to trick a user into running it.

Worms And Trojan Horses

A Worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well. The term worm was coined by John Brunner, a science fiction writer, in his 1975 novel Shockwave Rider. The hero, a talented programmer, created self-replicating computer programs that tunneled their way through a worldwide network.

A Trojan Horse is simply a malicious computer program that damages your computer system upon installation. The program claims to do one thing, such as pretending to be a game, but instead do something else when you run them. Some nasty Trojans will actually attempt to erase your hard drive. They were originally named after the historic Trojan horse used by the Greeks to conquer Troy because the first Trojan horse programs pretended to be innocent games or applications. Trojan horses have no way to replicate themselves automatically. Below you will find some of the various ways that viral related attacks can be transmitted and spread.


All of these are ones that I personally use and all are free.

Spybot - Search & Destroy detects and removes spyware, a relatively new kind of threat not yet covered by common anti-virus applications. Spyware silently tracks your surfing behaviour to create a marketing profile for you that is transmitted without your knowledge to the compilers and sold to advertising companies. If you see new toolbars in your Internet Explorer that you haven't intentionally installed, if your browser crashes inexplicably, or if your home page has been "hijacked" (or changed without your knowledge), your computer is most probably infected with spyware. Even if you don't see the symptoms, your computer may be infected, because more and more spyware is emerging. Spybot-S&D is free, so there's no harm giving it a try to see if something has invaded your computer.
