常规软件更新和修补程序的重要性

我们会不时看到这些弹出的小窗口,通知我们计算机存在可用软件更新。这些更新很可能经常在我们执行某些看似重要的任务时“显身”,为了省事,我们都会毫不思索地单击“以后提醒我”按钮。不久之后,这个小小的弹出窗口又折返,叨叨着让我们安装这些更新并重新启动计算机。就像它们上次拜访一样,不巧我们手头又在处理某项任务,毫无疑问又是对它置之不理,如此往复。但是,请记住该通知并不只是来“纠缠”我们的,因为更新软件实际上非常重要。

我为何要安装更新?

软件更新会执行无数任务,既针对我们的操作系统,也涉及各个软件程序。执行这些更新会对计算机进行大量的修改,如增加新功能、删除过期的功能、更新驱动程序、提供错误修复,最重要的是,修复已发现的安全漏洞。

软件漏洞的危险之处

软件漏洞通常是操作系统或软件程序中所发现的安全漏洞或缺陷。黑客通常利用这个薄弱环节,在恶意软件中写入代码以攻击特定漏洞。这些漏洞利用可能会感染你的计算机,其途径无非是让你查看网站、打开受感染的消息或播放受感染的媒体。

一旦它感染了你的计算机,此恶意软件就可以窃取数据,让攻击者掌控你的计算机,甚至是改变软件的原始用途。例如,最近的“Shellshock”攻击案例就是通过软件漏洞对 Mac OSX 和 Linux 发起攻击。

因此,即使这些软件更新看似恼人,但它却是保护你互联网安全的预防性措施。下次再弹出更新消息时,克服你的拖延症吧,单击“立即安装”按钮完成更新。

With all the bogus norton emails, pop-ups & fake sites what is the protocol in security on our accounts if there's a breach?

With a Windows 7 PC, will updates and patches alone from Norton Security Live Update provide enough protection?

I don't like to download Microsoft Updates as they either cause something not to work or slow the computer down.

I will wait until some of the above questions are answered, like Windows 7 PC, bogus emails & fake sites. How well can Norton prevent such breaches or refuse to allow the damage one may cause? That is, after all, why we purchase and depend of Norton. Still, you can help in a lot of situations so the potential problew won't happen. Like credit card companies and banks do at least partially now, always go to their web site in your internet browser and download from there. Don't trust anything that you can't verify if real. Just like giving out your SSN and DOB to some stranger that calls you on your phone.

It is incredibly easy to set things up so that when you click a link in your email that says it directs you to some web page, that you actually go somewhere else. I discovered this accidentally when I sent someone an email with a link in it. The link you would click on had you go to some other page. Norton did not prevent this from happening, although in this case the site you were directed to was a safe one Things might be different if the real site was disreputable.

I'm not going to tell how I discovered this because I imagine lots of people (that otherwise wouldn't know how to accomplish this). would really like to be able to do that.

Didn't Norton at one time have a vulnerability scan?  If I remember correctly they had something like that.   We all know patches are essential, I don't know why Norton doesn't have some kind of basic vulnerability type scan to make sure you are up to date on the latest updates, like flash, etc.  Other venders seem to be doing this, or at least it is said on there packaging.  I think it needs to be put in the suite.  How can we be protected, if the number one threat is probably a unpatched system?
