There are many anti-virus products which are available on the Internet or in high-street shops.
There are a couple of products that have been around for a number of years and have been found to be consistently good at identifying threats. One is supplied by www.kapersky.com; the other is supplied by www.f-secure.com. This doesn’t mean that other products won’t be as effective but some organisations have chosen to recommend these products to their customers. Packages can be purchased direct from manufacturers, from High Street shops and from other suppliers such as Amazon. Some are also available as free downloads from the manufacturer for a 30 day trial period, but you must ensure that you purchase a full license before the trial period expires otherwise the package will become out of date.
It is essential that your chosen product is set up to check for updates every time your PC is switched on. A typical update to the product will take a couple of minutes and will happen in the background. Ideally it should also be set up to perform a full scan of the PC once a week. The time when this scan takes place can be determined by you. Most products are also available as multi-license purchases if you have several PCs in your household.
