Internet Explorer is the default browser in Windows and because of this it is to be expected that there will be a very large number of users. Primarily, these will be people who do not want to investigate improved software for their PC and are happy with the default set-up; and office users who are frequently locked into using the default software.
It's fine to use the default apps that Microsoft provide, but just be aware that they are often not as good as other offerings. IE does work well as a browser and is entirely satisfactory for those who don't want to explore other options. However, there is a downside:
- Technically, it is a poor browser because it is not standards compliant
- It has some weaknesses that lead to exploits
- It is heavily attacked by hackers
Because it is a 'rogue' browser (not standards compliant), website developers have to make special arrangements for it in order that it can read a site correctly. This drives them all crazy as it is completely unnecessary, it's just down to poor coding at MS. As a result, whatever other benefits it might have, it is despised by techies.
Traditionally, it has always been the easiest to exploit. This means attackers who have hacked a website (or run attack sites) can more easily get into your PC. That is not to say other browsers have not sinned, just that IE has been the worst. All web software has been exploited at some time - there is no such thing as a web app of any kind that has not had a vulnerability demonstrated, and a website or user PC successfully exploited. However, part of the strength of an app these days (and some would say its most important feature), is how quickly and successfully the app's developers react and fix it. There is no argument here that MS have been by far the worst. If an exploit is discovered in Firefox (as they are, of course), the devs often fix it within a day or two. It has taken MS
three months or longer, at times. This is not acceptable.
Because it has weaknesses; because IE users are the most likely of all to have poorly-protected computers; because MS have often taken a long time to fix the problem; and because IE users are the least likely to have a patched and updated browser or other software: attackers concentrate on exploiting IE above all others. Therefore, if you use IE you MUST ensure that your PC is extremely well protected - as it will be attacked, and as the attack is much more likely to be successful than if you are using another browser.
Apart from having a good hardware firewall, a good software firewall, and a good antimalware app, you also need to keep your software updated. This is because many PC apps have vulnerabilities, and if you are using IE, an attacker is more likely to be able to get into your computer and exploit old apps successfully. This means that the hacker can get his software onto your PC and run his own programs, or even control the PC. It is how botnets are run: 20% of all PCs are actually controlled by a 3rd party.
Some of these vulnerable apps are: Java, Adobe PDF Reader, and Adobe Flash. If your run IE then you MUST update these apps regularly.
One of the best ways to do this is to use a free Software Update Manager. Gizmo's Freeware is a good source of excellent free resources like this, it has one of the highest reputations on the net, and has 100,000 visitors a day who use their information. Here is the Software Updater page:

There is nothing wrong with IE, if you like it. After all, that is the main requirement. It's just that you need to be aware of the issues.
