There is such a thing as overdoing things when trying to keep your computer secure and by doing so you may inadvertently weaken your security and AV protection, please see admin tutorial here
for recommendations for how to best keep your computer secure, you will note that AVG is no longer recommended.
Couple of other pointers for you;
I defrag weekly.
Unless you are a power user who continually swaps files backwards and forwards weekly defrags are way too much that will not only subject the HDD to unecassary stress but also create the very fragmentation that you are attempting to avoid, the average user need only defrag once every 3 months or so depending on usage, while it does not apply here it is also worth mentioning for others that may read this thread, never defrag an SSD.
I use WinZip Utilities.
Such programs are also not recommended on these forums, they are at best a gimmick and at worst a danger to your registry, an old but still often referred to blog from miekiemoe here and a thread on Wilder Security Forum here
To the problem at hand;
