Just a short guide for prevention of viruses and anti spyware entering your PC.

Always make sure you have anti virus and that it is a genuine product and is kept up to date. I personally use Blueyonder PC Guard as it is recommended by my ISP (Internet Service Provider) and has a built in firewall and anti spyware. I have used Norton Antivirus and AVG Antivirus in the past also and they have both been perfectly fine.

Always make sure you have an anti spyware installed on your PC and that it is a genuine product.

Always make sure all software etc that you download is genuine or there is a high chance viruses and spyware is included in the download.

Make sure your operating system is a genuine product.

If a virus is found on your system run a virus scan and see if the virus can be quarantined or deleted.
If this fails you can always re install your operating system and this should wipe the virus off of the system.

Hope this helps.

Thanks.
