    提高電腦安全的五大技巧

    時間:2015-10-30 15:22:21本文內容及圖片來源于讀者投稿,如有侵權請聯系xuexila888@qq.com 廣達 我要投稿

      電腦安全對于任何一個個人電腦來說,都是非常重要的,因為個人電腦中往往都保存著大量的個人信息,若被不法分子入侵,則會造成這樣那樣的損失,下面是提高電腦安全的技巧,希望學習啦小編整理的對你有用,歡迎閱讀:
     

      病毒和木馬是不斷“發展”的,我們也要不斷學習新的防護知識,才能抵御病毒和木馬的入侵。與中毒后再查殺,不如提前做好防御,修筑好牢固的城墻。畢竟亡羊補牢不是我們所希望發生的事情,“防患于未然”才是我們應該追求的。

      1、不要隨便瀏覽陌生的網站,目前在許多網站中,總是存在有各種各樣的彈出窗口,如:網絡電視廣告或者網站聯盟中的一些廣告條。

      2、安裝最新的殺毒軟件,能在一定的范圍內處理常見的惡意網頁代碼,還要記得及時對殺毒軟件升級, 以保證您的計算機受到持續地保護。使用具備防掛馬功能的安全軟件,如“瑞星殺毒軟件2010”等,可主動防御此類的掛馬網站攻擊(半年免費)。

    提高電腦安全的五大技巧

      3、安裝防火墻,有些人認為安裝了殺毒軟件就高忱無憂了,其實,不完全是這樣的,現在的網絡安全威脅主要來自病毒、木馬、黑客攻擊以及間諜軟件攻擊。防火墻是根據連接網絡的數據包來進行監控的,也就是說,防火墻就相當于一個嚴格的門衛,掌管系統的各扇門(端口),它負責對進出的人進行身份核實,每個人都需要得到最高長官的許可才可以出入,而這個最高長官,就是你自己了。

      每當有不明的程序想要進入系統,或者連出網絡,防火墻都會在第一時間攔截,并檢查身份,如果是經過你許可放行的(比如在應用規則設置中你允許了某一個程序連接網絡),則防火墻會放行該程序所發出的所有數據包,如果檢測到這個程序并沒有被許可放行,則自動報警,并發出提示是否允許這個程序放行,這時候就需要你這個“最高統帥”做出判斷了。防火墻則可以把你系統的每個端口都隱藏起來,讓黑客找不到入口,自然也就保證了系統的安全。

      4、及時更新系統漏洞補丁,有經驗的用戶一定會打開WINDOWS系統自帶的Windows Update菜單功能對計算機安全進行在線更新操作系統,但是為了安全起見,推薦使用免費瑞星卡卡助手6.2來給系統打補丁,并攔截掛馬網址。

      5、不要輕易打開陌生的電子郵件附件,如果要打開的話,請以純文本方式閱讀信件,現在的郵件病毒也是很猖狂,所以請大家也要格外的注意,更加不要隨便回復陌生人的郵件。 當別人問起我的電腦已經被木馬或者流氓軟件牢牢控制了,我們拿什么去跟它們對抗呢,憑什么說我們是最終的勝利者呢?我們不得不采取以下措施挽救我們的電腦。

      我們個人對電腦安全所能做的,就是及時的更新系統補丁和殺毒軟件,因為我們不具備多么深的系統安全知識,所以只能依賴于他人開發的各種軟件,另外,還要養成良好的上網習慣。
