Macfee VirusScan 延長線上更新的辦法
 

我在公司的電腦上試了 VirusScan Professional 7.02 版，似乎沒有問題，更新的有效期限從 365 天
增加到 7300 天，我沒試過其它版本，如果你們在用 McAfee 的 VirusScan 其它版本，幫忙試試吧！

1. 首先執行 regedit，找到 HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\Instant Purchase.00\LM\FDXA-RAA

2. 把該 key 匯出到一個檔案（請先制作備份），再用 notepad 開啟，你會看到像下面的文字：

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\Instant Purchase.00\LM\FDXA-RAA]
"Data"=hex:48,43,41,41,41,41,59,51,33,36,58,41,56,35,34,48,4c,57,53,51,46,57,\
4c,4b,46,51,44,4b,47,44,34,55,33,44,59,36,35,47,4c,4b,56,57,5a,42,35,33,4d,\
48,33,32,5a,57,46,47,53,34,4c,50,32,41,41,41,41,41,41,41,41,41,41,41,58,34,\

4c,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,59,\
58,4a,41,52,41,41,50,41,41,36,41,41,58,36,41,59,4c,41,56,4d,41,41,58,4a,41,\
35,38,50,43,4c,41,59,41,41,56,41,41,41,4d,41,41,55,41,41,48,52,41,41,38,50,\
56,4e,52,41,41,41,41,55,50,47,41,35,37,4c,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,56,35,34,48,4c,57,53,51,46,57,4c,\
4b,46,51,44,4b,47,44,34,55,33,44,59,36,35,47,4c,4b,56,57,5a,42,35,33,4d,48,\
33,32,5a,57,46,47,53,34,4c,50,32,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,4c,41,41,41,41,41,58,41,41,41,41,41,56,41,41,41,41,41,41,35,\
33,53,58,35,48,4c,43,41,50,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41

3. 把紅色字改成 57 56 5a，像是下面的樣子：

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\Instant Purchase.00\LM\FDXA-RAA]
"Data"=hex:48,43,41,41,41,41,59,51,33,36,58,41,56,35,34,48,4c,57,53,51,46,57,\
4c,4b,46,51,44,4b,47,44,34,55,33,44,59,36,35,47,4c,4b,56,57,5a,42,35,33,4d,\
48,33,32,5a,57,46,47,53,34,4c,50,32,41,41,41,41,41,41,41,41,41,41,41,57,56,\
5a,41,41,41,41,43,34,59,41,41,41,41,4d,4c,50,41,41,41,58,35,48,41,41,41,56,\
4c,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,59,\
58,4a,41,52,41,41,50,41,41,36,41,41,58,36,41,59,4c,41,56,4d,41,41,58,4a,41,\
35,38,50,43,4c,41,59,41,41,56,41,41,41,4d,41,41,55,41,41,48,52,41,41,38,50,\
56,4e,52,41,41,41,41,55,50,47,41,35,37,4c,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,56,35,34,48,4c,57,53,51,46,57,4c,\
4b,46,51,44,4b,47,44,34,55,33,44,59,36,35,47,4c,4b,56,57,5a,42,35,33,4d,48,\
33,32,5a,57,46,47,53,34,4c,50,32,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,4c,41,41,41,41,41,58,41,41,41,41,41,56,41,41,41,41,41,41,35,\
33,53,58,35,48,4c,43,41,50,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,41,\
41,41,41,41,41,41,41

4. 存檔，然後對該檔案雙按滑鼠左鍵，Windows 會問你要不要匯入該檔，選「是」，然後你再開啟 McAfee VirusScan，
看看 about 裡面的日期有沒有增加，有就成功了！

5. 如果日期增加了，反而會造成 Instant Updater 不能更新，請把第 2 步制作備份的檔案匯入 Windows 還原，
這樣子應該就可以了。

你看到的值可能不是像紅色字的值，而是其它的值，不過我想只要修改同一個位置，改成藍色字的值，應該是
有作用的。

我是下載網路上的程式，然後比對他們對 registry 做了那些更動，發現改這些就有作用，而網路上的程式，
改了之後時間會增加沒錯，但是卻沒辦法 update。所以你們可以試試這個方法，如果有效的話，也請你們發
表一下成功的版本吧！

真的有效喔....
