I had a bunch of viruses on my computer and I kept getting more because one of them hijacked mcafee, preventing me from turning it back on. I tried to restore my system to an earlier date but all the restore dates were too recent so I decided to reinstall windows 7. I didnt have the disk any more so I downloaded it to a usb drive. I succesfully installed it, but when I logged in I noticed it looked completely different. The bottom bar was much larger then it was before, The screen looks zoomed in and the shortcuts are all much bigger, and when I go into control panel or computer the windows take up the entire screen and cant be made smaller, only minimized. Could I have downloaded a wrong version of windows 7? I also failed to realize that I would need to install all new drivers and was very confused when I couldn't connect to the internet. I tried to install the drivers by looking them up with the network cards ven id but it says they aren't supported on my device. Any help will be greatly appreciated as I have no clue what I am doing. If it helps I have a dell xps 8300.
