CCeaner (originally Crap Cleaner) is useful for clearing space on a hard drive. It also has a nice Startup Editor, I know you can do this with msconfig but you can also see and control your browser start up progs.
As Ab Editor says, it won't directly remove malware.
I have done malwarebytes - and it give things detected and asked me to shut down which I did - now I am running CCcleaner - but before I went further there it said if we clean you will lose files - are you happy with that (something like that) - what shall say - I don't want to lose important files if you like. Thanks Am waiting here before i go back to ccleaner which is minimised at the moment
CCleaner will delete temporary internet files, files from your recycle bin, cache files and temporary files.
You won't lose anything important.
Just out of interest, what is the total amount of data it wants to remove?
Purely my opinion. CCleaner is dangerous in the wrong hands. It's a Registry cleaner and I think such items can do more harm than good. Could even upset Windows to a non-repair level.
done ccleaner anyway - and had to re-log into here - and my outlook - couldn't believe had to start to hunt old passwords - god knows how many I will have to log onto again. no would not have recommended but no harm done - I hope.
