How to protect a laptop from spam, viruses

Q&A: Expert Richard Brain explains how to protect your laptop from malware by preventing it from installing in the first place.

What is the best way to protect a laptop from all types of viruses or spam?
The best way to protect a laptop from viruses and spam is to prevent malware from installing on the laptop in the first place.

For a start, antivirus software and a firewall should be installed. When browsing the Internet, use an account which does not have administrator rights. This will prevent the laptop from the majority of malware attacks, with insufficient permission to install the malware.

It's also important to configure Web browser security settings so that frequently used trustworthy sites have lower settings than other untrustworthy ones. The settings ensure that potentially dangerous browser extensions are disabled when visiting untrustworthy sites.

Behaviour is also important in preventing infection. Users should be educated to work safely. They should be made aware that untrusted websites, emails or even USB storage-based devices should be viewed with suspicion, and seen as potential sources of malware.

Finally use a modern operating system and ensure it is patched frequently. Modern operating systems have numerous protective mechanisms against buffer overflows, and frequent patching will protect a laptop against malware that uses the latest exploits.
