Unfortunately, not everyone on the Internet is your friend. There are a number of ever-present threats nowadays, such as Viruses, Trojans and Spyware. Unauthorised access to one of your computers can be used to plant these offending objects, however the main route of attack is often an unwitting download by someone at your end.

There is no "silver bullet" which can guarantee to cure all network security threats. Just like with human health, computers can and will sometimes get "ill". The aim must be to stop the infection spreading and to "get well soon".

Data "hygiene" and Threat Containment and Management are mature approaches to security. No magic potions, no impossible promises but constant vigilance and preparedness.

Tools like Anti-Virus are of course a useful measure to tackle a large section of the daily threats. But there are always some threats that can get past standard tools, so you should seek expert professional support for your IT security too.
