I am currently considering improving my laptop security, which hasn't evolved for 2-3 years. It was Outpost FP + NOD32 + Spy Sweeper, and now it is what's on my signature. Sandboxie + SD (the latter definitely not activated all the time) only since yesterday, but they look great. I might drop NOD (unless v4 has impressive detection rates) and Spy Sweeper (no longer what it used to be). Well, here are my points : 1) OSS 2009 is much better with Smart Scan, simply because scanning processes are incredibly faster, as everybody knows. However, it is disabled when 3rd party resident protection softwares are detected. Would it work with Prevx Edge and/or SAS pro ? If so, without any conflicts ? 2) If not, would you say OSS 2009 + MBAM on-demand are more than enough, coupled with Sandboxie (and even SD now and then) ? 3) Would Prevx Edge and/or SAS pro add much greater protection ? Slightly better ? Not worth buying (this isn't about the softwares themselves, but taking my other security softwares into account) ? Thanks a lot for your help. I would just like to avoid superfluous choices (and expense), no matter how great all these softwares can be. Sometimes 3 are better than 5 or 6, I guess.
