Hi
Defraggler doesn't remove anything it just defrags the files so they aren't spread all over the hard drive.
I use it regularly.
Download Defraggler 2.06.328 - FileHippo.com I recommend that everyone use CCleaner from the same people who make Defraggler.
Piriform - Download CCleaner, Defraggler, Recuva, Speccy - Millions of users worldwide! I've used it for years and it has never caused my any problems, I run it every day.
Note that CCleaner removes cookies but has a place to tell it what cookies you want to keep.
You should use Malwarebytes.
Link Removed - Invalid URL It will get rid of unwanted malware.
And you should use Microsoft Security Essentials or some other Antivirus Software along with Windows Firewall.
Other then that I wouldn't mess with most of the stuff, these programs should keep you computer clean and safe.
If you are using McAfee my
personal opinion is that I would get rid of it, it's very intrusive and puts a lot of drag on you computer performance.
