I hope this is the right place to post this, but I installed CCleaner at the advice of a trusted acquantance who works in an IT department.
He ran CCleaner on my work computer, with no apparent problems. Since my home computer likely could have used the services of CCleaner, I decided to run it on my system, and I am very sorry I did.
Perhaps, the problem is me, but since I have run CCleaner, my Firefox browser crashes every time I open a YouTube channel, the Steam client will not run on my computer no matter what I try, and I'm slightly afraid that other programs on my computer have also been destablized.
I talked with the product support of my antivirus program, and they mentioned the fact that CCleaner can delete files programs need to run.
That probably is the case; however, the two programs I'm having the biggest problem with (Steam and Firefox) have both been reinstalled since the CCleaner session, and neither are working properly to this present moment.
Any ideas on how to get my computer working properly again? I really don't want to do a system restore, but I feel I may have to do so.
Any help is appreciated.
EDIT: Firefox is fixed now.
