Ok, I have been struggling with an issue for the past 2 days. It's the first issue I have had on this computer with Windows 7 since I installed it well over a year ago.
Ok, I never really had any anti-virus software on the computer because a buddy of mine said he ran Windows 7 without anti-virus and didn't have any problems. Neither did I after 6 months, but finally caved and installed AVG 8 just in case. Also, I installed "Advanced System Optimizer" because I had it on XP and remember it being a very good program all around. Well, after a couple months it started bugging me about not having a legit copy (hahaha), so I got sick of that garbage and decided to uninstall it, along with Yahoo Messenger which I don't even use anymore. - Advanced System Optimizer uninstalled just fine. Then I uninstalled Yahoo Messenger and just at the end of the uninstallation, it gave me a "missing WINTRUST.DLL" error message. It removed Yahoo Messenger from my programs list, but I remained concerned about the DLL error message.
So, I shut the computer off and come back the next day. I turn the computer on, click on internet explorer and go to Yahoo. I notice that in the corner of the page it says I am still logged into one of my email accounts on Yahoo. I click "sign out" and it sends me to a connection error page saying "Internet Explorer cannot display the webpage". The address for the page is: (http://mail.yahoo.com/;_ylt=A0WTfZh6cSJNWGkBtQObvZx4?.intl=us
). I thought nothing of it, went back to Yahoo and tried it again. Same error. So I'm thinking Yahoo is having problems, right? Wrong. I couldn't log into Facebook, YouTube, or any other site either! Still can't!!! I went on my other computer and I could log in fine, so right there I knew I had a problem. Then I discovered I couldn't download anything at all. It says it's downloading, finishes... and then the file never shows up on the computer.
Long story short, I thought maybe it was an Internet Explorer issue, so I downloaded Firefox for the first time. Firefox allowed me to log into all of my online accounts (Yahoo email, Facebook, YouTube, etc)! Checked IE again and it wasn't working, but Firefox works? However, none of my downloads on Firefox work either. Nothing will download. So in order to fix this issue, I looked up "WINTRUST.DLL" on the internet. Of course, I could barely find ANYTHING helpful. I tried un-registering the wintrust DLL, then re-registering it using the command prompt. Didn't work. Still says it's missing. BUT..... I looked in the system32 folder and sure enough.... there it is, NOT missing. What the (blank) is going on?!?!?!?!
Somebody please help me! This is not a malware issue, because it happened when I uninstalled the Advanced System Optimizer. It somehow deleted WINTRUST.DLL, but I can still see it in my system32 DLL list. Somebody help!
