The issue with Yahoo and with GoWilkes are two different issues, but may have the same source. It's very possible that you have a virus.
FWIW, while Umpire was joking, it's true that a lot of viruses come from adult sites. I read an article awhile back, though, that said that the majority of viruses now originate from Facebook. A lot of the "apps" that you install are written by 3rd parties, and it's easy for the writer of the app to implant a virus.
One of the common things that a virus will do is log in to your email account, change the password, then use it to email people you know (posing as you) to ask them to send money.
Regardless, the first step would be to scan your computer for both viruses and spyware. If you don't already have good programs for this, then go to
http://www.download.com and download both AVG Antivirus Free and Malwarebytes Anti-Malware. Both are excellent free programs. Scan your computer with both, let them remove anything that they find, then restart your computer.
If this doesn't help, then on GoWilkes, I would first try setting the browser back to its default settings. On your keyboard, press Control + 0 (that's a zero, not an o). This will set the "zoom" back to the default 100%. If that doesn't help, then in the upper right of this thread, you'll see "- A +" (where you can increase or decrease the font size). Try clicking the "A" in the middle, and it should return the font to its default size.
If that still doesn't help, please send me a screenshot of the page, so that I can try to diagnose it better. The easiest way to do that is to press the PrintScreen button on your keyboard (it may also say "PrtScn", but it's usually beside of F12), which will place a copy of the screen in your computer's memory. Then, go to an email, and paste the image in the body by pressing Control + V. Send the email to jason@gowilkes.com
If you can't get the email to work, you might find it easier to paste it in to a Word document, save the document, then send it to me as an attachment by Private Message.
I'll move this thread to Tech Talk later this evening, so please post any updates there. Good luck!
