Virus? (Not from forum)

[BlibbityBlabbity]

As for the first part.....in Internet Explorer go to Tools/Internet Options/...

Then in the top box called "Home Page" you can set the page that opens every time you open your browser.

How are you "checking your mail" that causes a web page to open? You might want to get some spyware/adware scanner(s) to see if you might have something running in the background, but there are websites that have scripts on them that "just" redirect your homepage.

If after you reset your homepage, and a few days later (or as soon as you restart your computer) it switches back again, then you likely have something devious (but not "necessarily" dangerous) on your computer.

Antivirus, Spyware scanner, and adware scanner will usually clean it up.

Good Luck
