is there an available software on the net that can really protect my pc?

Yes, there is an available software that you can download for free, for the sake of protecting your PC from malwares. Currently, I have been using Avira Antivir Personal Classic Edition, which you can download for free at www.free-av.com Have a nice day and hope this would help!

To get powerful antivirus, you need to buy it. If you download for free, free adsware and spyware will come to you pc too...

I have been using free Avast anti-virus for home edition which is really good and decent free antivirus to protect your pc.

use a firewall, antivirus and spyware if you are using xp pro then there is already a built-in firewall for antivirus you can use avast or clamwin these are free as far as I know for spyware I recommend spybot (search and destroy)

yes install firewall like Zone Alarm and install antivirus like symantec or nod32 .. have a good day without virus or trogen ..

Yes you can use firewall security. That can be download from net. Also you can use Macafee as your protection software.

For a long time now I am using NOD 32 and I feel that this security suit is very good and efficient. It is very easy to use. The scanner works very fast. It is a very fast and well equipped firewall which never gives any problem and works on a computer pretty well unstuck all in all I feel it is a very good choice. It has regular updates so you can the Congress tension free about the new virus threats.

theres a lot of antivirus software available but if you really want to protect your computer against viruses and other attacks i recommend you to use "Deepfreeze". deepfreeze is the absolute PC protection. Deep Freeze instantly protects and preserves original computer configurations, eliminating routine IT maintenance while allowing complete unrestricted access to a workstation. Regardless of the changes made to a workstation, simply restart to reset the computer to its original state. The result is a protected, parallel network, free of viruses and unwanted programs. ever since i use deepfreeze i never have to buy and use anitvirus, antispyware, anti-trojan and other pc protection to protect my pc.

I agree that avira antivir is one of the best antivirus available. Install it and you should be fairly safe enough from everyday threats around the net.
