It can cost nothing to protect personal computers against viruses, spam, spyware and other malware, says consumer activist group Which?.
Its latest magazine explores the best PC security freeware against commercial products. It found most do an excellent job of the basics, but commercial packages provided extra features and all-in-one ease of use, for about £40-£50.
Which? picked Avg's Anti-Virus as the top bug killer, and chose Microsoft's Windows Defender as the best free spyware preventer. BullGuard's spam filter took the honours for cleansing e-mails, and Checkpoint's ZoneAlarm got the nod for best free firewall.
Which? also offered some security tips:
- Download with caution
- Do not respond to spam
- Keep software updated
- Do not use a single password or store it on or near the PC
- Do not respond to phishing messages
