notebook 防毒幾時過期?

If you are running Windows 8, you don't need any of these. Reasons being:

1. Win 8 has Windows Security Essentials built in. All you need is to type Windows Defender in the search box and hit return then follow the prompts on screen to scan. Microsoft updates the definitions on every second Tuesday of the month. Make sure you remember to run it after that day. Absolutely free service. Designed for Windows 8, backed up by Microsoft. What's the worry then?

2. Go into the settings for Windows Defender. In here you can reduce the CPU usage while scanning and fine tune it to minimize lagging on your PC performance. Something that I've found much superior to the other anti virus programs. I've used AVG Free for more than 10 years and put up with that nuisance until I gave this a try and found it OK for the last 6 months.

Run it then delete the McAfee (with 28 days left, you're right) if you like the change. Next time when you update Adobe reader, make sure you uncheck the box in the middle pane where McAfee tries to sneak and get through with the update.

If you don't pay after 28 days, McAfee will quit and expose you to viral attacks. If you don't delete it, it'll keep popping messages to urge you pay.

廠機附送的防毒，由以前一年，減到半年，三個月，一個月都有，夠期個軟件係不能更新病毒資料，好過冇，不過功能越來越等於冇。
到時會出個warning，叫你付費續期。
若不打算續期，其實建議你立即安裝另一個，建議avg或者avast，於download.com，右手方最多下載一二位。個人喜歡avg一點，其實avg也有付費版，功能較全面，但由於用相同病毒檔，所以認毒同付費版應相同。
安裝時選"基本"即係免費，一世。或者直至該公司轉條款。
其實無謂等那28天，冇意思，各防毒軟件認毒大致係九十幾巴仙，送你的28天不會有明顯安全或不安全。建議你現時有時間便剷走佢，裝新，因到兩三個星期後你可能已忘記這件事，反而更不安全。不要同時裝兩個，慢，安全度可能只係多一兩個巴仙。但兩個防毒會令操作慢，有時甚至撞。
