No single product is 100% foolproof
and can detect and remove all threats at any given time. The security community is in a constant state of change as new infections appear. Each vendor has its own definition of what constitutes malware and scanning your computer using different criteria will yield different results. The fact that each program has its own definition files means that some malware may be picked up by one that could be missed by another. Thus, a multi-layered defense using several anti-spyware products (including an effective firewall) to supplement your anti-virus
combined with common sense and safe surfing habits provides the most complete protection.
However, you can overkill your system with resource heavy security programs that will drain your resources and slow down performance. Sometimes you just have to experiment to get the right combo for your particular system as there is no universal solution that works for everyone.
Everything your using except for Zone Labs Security should not be running in real-time mode unless you purchased the upgraded versions of AVG AS or SAS. If that's the case, then your using them as stand-alone scanners which is fine. I would probably eliminate the use of Ad-aware SE. Although definitions updates are still available, support may end at some point. The new version is much larger in size (18,694 KB) because in includes additional enhancements available only if you choose to purchase them. This is not very helpful to those who only want to use the free features. Although it has a new look, Ad-aware 2007 does not seem to offer much in major improvements with its scanning.
As far as Reg Supreme goes!! Registry cleaners are extremely powerful applications
. There are a number of them available and some are more safe than others. Keep in mind that no two registry cleaners work entirely the way. Each vendor uses different criteria as to what constitutes a "bad" entry. One cleaner may find entries on your system that will not cause a problem when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
The Windows registry
is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component
because it is where Windows "remembers
" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system unbootable.
The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results
". Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly can have disastrous effects on your operating system such as preventing it from ever starting again.
For routine use by those not familiar with the registry, the benefits to your computer are negligible while the potential risks are great.
