.-- Web Security Guard is included in the download but not required. After installation you will be prompted to Enable Web Security Guard Toolbar. This browser add-on (similar to Site Advisor) is enabled by default so be sure to uncheck the box if you do not want it installed. If you install WSG by mistake, it can easily be removed later via Add/Remove Programs in Control Panel.
-- If you already have an anti-virus application, there is no need to install the optional Clam AntiVirus integration. ClamAV does not have a real time scanning engine but you can integrate it into ST's Realtime Shield to include virus scanning support.
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. mvps.org
is no longer recommending
Spybot S&D or Ad-Aware due to poor testing results. See here
- (scroll down and read under Freeware Antispyware Products)
Further, most people don't understand Spybot's TeaTimer
or how to use it and that feature can cause more problems than it's worth.
While not free, I recommend using Malwarebytes Anti-Malware
and taking advantage of the Protection Module
which uses advanced heuristic scanning technology
to monitor your system and provide real-time protection to prevent
the installation of most new malware. This technology monitors every process and stops malicious processes before they can infect your computer
. The database that defines the heuristics is updated as often as there is something to add to it. Enabling the Protection Module feature requires reqistration and purchase of a license key that includes free lifetime upgrades and support. After activation, Malwarebytes can be set to update itself and schedule scans automatically on a daily basis. The Protection Module is not intrusive as it utilizes few system resources and should not conflict with other scanners or anti-virus programs.
