Defragging is good, but you can trust the system when it states that it isn't necessary at the moment.
Your problem is likely due to installing software of questionable sources. In other words, don't download and install software unless you know exactly what you are getting.
Good anti-virus, anti-spyware, and firewall software is very important to prevent rogue software from taking over your system, and hurting system performance.
This is correct........I recommend AVG Free Antivirus, Windows Defender(New version) and a properly configured router .....Defrag was a FAT issue, and NTFS is much better
