AVG initialization error:

I tried to unistall AVG antivirus on my laptop. It actually showed that it was suceesfully uninstalled. but when i tried to install another antivurus software, Panda, it failed to install as it shoed the follwing error,

Installer initialization failed due to following error:
Error: @AvgErrorCode_0x0253 %FILE% = "C:\Program Files\AVG\AVG8"
@AvgErrorCode_0x0020

Now i cannot install another antivirus and any software and i fear my laptop was corrupted and infected with a virus aslo. How should i go about it?

Run a full anti virus scan
Download and run a full scan with malwarebytes
If all are negative with system restore go back to a point prior to the uninstall and I will tell you how to uninstall with the uninstall tool.
