KLMNO...you have a virus if I remember from the last thread. At this point while you can still download anything, get Malwarebytes, Advanced System Care and AVG. Then make sure you copy over to disks everything you could possibly need for future reference. I prefer to store quite a bit online. You can copy all your bookmarks onto google bookmarks. Move all saved emails to an online email account if you use outlook. Save all pictures and documents. Then make back up disks if you havent. Then I would run Malwarebytes in safe mode and then Avg in safe mode. Oh...make sure you download the latest updates to both of them before you do all of this. If this doesnt fix everything you are going to have to use your back up disks to reformat your computer and start it from scratch. Pain in the rear but it is what it is. Sometimes you just have to do it.
DDD...your issues are different I think. I am assuming AOL is your internet provider. I hate them by the way. You could do so much better. However, for the moment, AOL is simply a browser getting you onto the internet. I am assuming when you say you cant post on AOL you are not trying to post on some AOL board right? If so, well I will have to work you through that a bit differently but if you mean you are just trying to post to places like our board but through the AOL browser, well I can help you fix that.
Do you have a dsl line, cable line or simply a phone line coming in your house? Since you say AOL, I am expecting its phone. When you get on with AOL, simply hit the little box at the top right hand corner to minimize the screen, then you can use any of the browsers. IE, Firefox or Chrome. Which edition of windows are you running? XP, Vista, or Windows 7? I would also download the free virus software and also advanced system care. You need to run them both immediately because they will speed up your system by a ton. I am sure your system hasnt been taken care of in years. It probably needs lots of windows updates too. You have no idea what bloatware is on there. I would use either firefox or chrome instead of IE. They are faster. I hate IE.
