New viruses can often get around anti-virus software because anti-virus software just doesn't know about them. Here are our top tips for avoiding viruses:
- Use a proper firewall. If you're plugging directly into a cablemodem, it makes sense to go and buy a router which puts a physical barrier between you and the internet. Ask your local computer store for help.
- Don't download dodgy software. Hackers often use tempting lures such as bootlegged software to install nasty viruses on your PC. If it looks like a website you can't trust, don't download anything from it.
- Don't open spurious email attachments. Not even from friends, if you're not sure what the attachments are.
- Keep up to date with "Windows Update". This removes malicious software on a regular basis.
