You can do these within each browser. No need CCleaner.
Also, there is no real need for registry cleaners. It causes more harm than good, as it is not intelligent enough to know what dll are shared and what else is there.
All the time when the computer lags, it is NEVER because of registry and its dead end links, whatever. Such dead links do not and will not cause your computer to slow down at all.
Anyone who miraculously realized his computer speeded up after cleaning is having the placebo effect.
For malware and viruses, use a good anti-virus and anti-malware software. You dun use a registry cleaner to rid your computer of such.
