AVG secure search installed virus in my computer

[aakarshan]

Last night i have installed a Iso software with a Typical Download Manager,With that a AVG secure search came.which i have also installed on my computer.After that my firefox crashed and i closed my laptop immedietely.
After that my laptop started hanging and stopped on boot screen,after that somehow i got access to my laptop.but after that there's a weird issue came up
The open/save dialog in 3rd party apps like firefox,facebook,other softwares doesn't come up and even i can't upload something on facebook.

I Searched AVG search in C drive in program files and after that i found it's folder.and i found a uninstall application,but on clicking that not starting and that cannot uninstall this AVG search.

Also i have seen that it is refusing many downloads on my firefox.Saying that it contain virus,but that never happened before.

I have noticed some dll hosts are running on my laptop and cpu usage has also changed.

A weird software is also running which i can not close atieclxx.exe.

Ran Malwarebytes and Adware Removal Scan but nothing seems to be found.

Pls Help.

atieclxx.exe. is an ATI (Radeon) graphics card driver enhancement.

Do a checkdisk.

Already done the checkdisc and everything came fine.Result is 'Windows Resource Protection did not find any integrity violations.'

Do a System Restore back to before the download.
