Windows 7 trouble after deleting Security Shield virus

My computer recently became infected with the security shield virus. To get rid of the virus I followed steps provided online. restarting my computer in safe mode with networking using lan settings downloaded rkill, iexplorer.exe, malwarebytes anti malware. I successfully got rid of the virus afterwards it recommended deleting my host file and downloading a new host file. Since that time my internet do not have the right format such as sites like yahoo will display images but not all the appropriate shading and decals and appears very boxy. on espn the background is white instead of the normal red. the reason i think it may be a problem with windows is when my computer sits and then goes back to the page to select the user however instead of the normal blue it is white on that page. please help if you can I am at a loss. I am not very computer savy and tried describing what is going on the best I can, thanks for any help

Are you sure the infection is gone? Run one more Malwarebytes full scan to see.

Then test for damaged System files by running SFC -SCANNOW Command. Report back results.

thanks for the advice both turned up with no issues. any other advice?
thanks

Are the remaining problems limited to your Internet browser? If so reset IE9 to Defaults at Internet Options>Advanced. Then only add back Add-On's as needed, starting with a fresh download of Flashplayer, Java.

I would also replace your AV with Microsoft Security Essentials and the Win7 Firewall. Run a full scan, make sure Windows Updates are all installed and it is set to Automatic.
