Welcome to BC benaa
Sorry to hear about your encounter with the XP Security rogue.No single product is 100% foolproof
and can prevent, detect and remove all threats at any given time. Just because one anti-virus detected threats that another missed, does not mean its more effective. The security community is in a constant state of change as new infections appear and it takes time for them to be reported, samples collected, analyzed, and tested by anti-vendors. Security vendors use different scanning engines and different detection methods such as heuristic analysis
or behavioral analysis
which can account for discrepancies in scanning outcomes. Depending on how often the anti-virus database is updated can also account for differences in threat detections. Independent Anti-virus software Comparisons & Tests
These kinds of comparative testing results will vary
depending on a variety of factors to include but not limited to who conducted the testing, what they were testing for (type of threats, attack vectors, exploits), what versions of anti-virus software was tested, what type of scanning engine was used, and the ability to clean or repair. There are no universally predefined
set of standards or criteria for testing which means each test will yield different results. As such, you need to look for detailed information about how the tests were conducted, the procedures used, and data results.

Choosing an anti-virus is a matter of personal preference, your needs, your needs, your technical ability and experience, features offered, user friendliness, ease of updating (and upgrading to new program release), ease of installation/removal, available technical support from the vendor and price. Other factors to consider include detection rates and methods, scanning engine effectiveness, how often virus definitions are updated, the amount of resources the program utilizes, how it may affect system performance and what will work best for your system. A particular anti-virus 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 and there is no best anti-virus
. You may need to experiment and find the one most suitable for your needs. For more specific information to consider, please read Choosing Your Anti-virus Software
A multi-layered defense using anti-spyware products (including an effective firewall) to supplement your anti-virus combined with common sense
