I had heard there are still people in the world that use IE. I didn't want to believe it was true.
Reasons not to use IE: it's absolutely freaking terrible.
Reasons to use Google Chrome or Firefox: they aren't IE.
Try Google Chrome or Firefox. Or download both. I had to try both to decide I like Firefox better, my hubby prefers Chrome. The only thing I don't like about Firefox is that every once in a while Flash crashes (which means videos won't play - but all you have to do is restart the browser to fix it)
We NEVER use IE. It's a very insecure browser.
Also, you can have tracking cookies and malware without knowing it, also many Antivirus programs don't catch all of them, which is why I have good anti-malware programs, such as the free versions of Ad-Aware and MBAM.
