Choosing a security toolkit with anti-virus, firewall and anti-malware programs is a matter of personal preference, your technical ability and experience, features offered, the amount of resources utilized, how it may affect system performance and what will work best for your system. A particular combination that works well for one person may not work as well for another. There is no universal "one size fits all" solution
that works for everyone. You may need to experiment and find what is most suitable for your needs. Another factor to consider is whether you want to use paid for
products or free alternatives
.No single product is 100% foolproof
and can prevent, 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.
Webroot should not conflict with avast. As a general rule
, using more than one anti-spyware program like Malwarebytes' Anti-Malware, SuperAntispyware, Spybot S&D, Ad-Aware, etc will not conflict with each other or your anti-virus if using only one of them for real time protection and others as stand-alone scanners. In fact, doing so increases your protection coverage without
causing the same kind of conflicts or affecting the stability of your system that can occur when using more than one anti-virus. The overlap of protection from using different signature databases will aid in detection and removal of more threats when scanning your system for malware. However
, if using all their real-time resident shields
(TeaTimer, Ad-Watch, MBAM Protection Module, Spyware Terminator Shields, etc) together at the same time, there can be conflicts
when each application tries to compete for resources and exclusive rights to perform an action. Additionally, competing tools may even provide redundant alerts which can be annoying and/or confusing.
Windows 7 Firewall is similar to Vista but adds a few new features in the firewall and related network-safety areas such as separate configuration settings for private (Home or Work) and public networks.
What's new in the Windows 7 Firewall?Security in Windows 7: Firewall and Networking
As with Vista, the basic settings for the Windows 7 firewall are accessed via the Control Panel applet. Unlike Vista, you can also access the advanced settings (including configuration of filtering for outbound connections) through the Control Panel instead of having to create an empty MMC and add a snap-in...
