About Free Anti-Virus Software.

Thank you for your question.   There are many free anti-virus software programs you can download and use.  What happens many times, is that after a while software companies update their products.  When this happens they try to get you to buy the new version, but you don't have to.  There is still a free option.  Here is a link to download the most recent FREE version of AVG, one of the most popular free anti-virus companies.

Make sue you click on the button that says "Download Now" on the left hand side.  Do not click on the "Premium Upgrade" that is for those wishing to buy the product.

There are other free anti-virus software companies such as Avast and Avira.  These are also good at protecting your computer.  However, updating them could be tricky as you have to make sure to search for the free version.

I hope that answers your question.  Thanks again.
