Double Clicking C drive gives an “Open With…” Dialogue list.

This issue is most certainly the byproduct of a virus hitting your system and subsequently being cleaned by an anti-virus product. I strongly suggest you do a full system scan in safe mode with your anti-virus security suite of choice with virus definitions updated before doing anything else.

To fix the Open with issue you will need to open a command prompt window by clicking the start button then run and typing “cmd” into the run box and click on Ok

In the command window type in the following commands “cd \” to take you to the root of the c drive. Then “attrib -r -s -h autorun.inf” then “del autorun.inf” as shown below. This will delete the Autorun.inf  on the hard drive placed there by the virus or malware.

Now to reset windows so it will open your drives without the “Open with…” message you need to run the command “regsvr32 /i shell32.dll” in a run window and click Ok.

After a few moments you will get a message stating “DllRegisterServer and DllInstall in shell32.dll succeeded.”
