Serious Problem With My WordPress :(

I’ve had some serious issues with my wordpress blog since the beginning of MAY 2010…

When I first try to get to my log-in screen to edit my post. I get A pop up saying ” Your Computer is at risk of a malware attack… and it redirects me to another page acting like its scanning my computer…

Now that happens where ever I try to log into my back office at. whether its at work, my friends, or even on my iPhone!

Now once I finally get into my back office, it is completely messed up

I do not know HTML or any CODING so I do not know where to look…

but the back office is in a column view you can see a picture of it at the link below

Its been like that since I’ve been having this problem…

Then after that I went to my blog and my RSS feed saids UNKNOWN FEED

I have version 2.9.2 and I haven’t done any editing to the code or anything for over 2 months…

Can someone please help me out
