Please Help!

Please help! I downloaded and installed avast virus cleaner and am having big problems with my pc. I have to uninstall and reinstall it.
I have tried this support site you have here and it boots my pc! - so can’t get on there.
There is nothing in my add/delete programs that ressembles avast virus cleaner or in my programs. I did a search and it said C:\Documents and Settings\alice
but I can see no way to uninstall the file - which is sitting on my desktop
Can you show me how? perhaps it is in my add/delete programs but there is nothing under avast there or anything like it.
There are 3 Sonic ones- audo dvd etc.
I seem to remember ‘Sonic’ being at the top of the file as it was installed.
Thanks
