I've explored the option of running only non-signature security software, not without drawbacks. Since I will be dumping my current AV very soon, I've been looking for a replacement. I don't know who stated it on this forum, paraphrasing 'AVs tend to catch spyware earlier than antispyware applications'. And while many, if not all AVs virtually ignored spyware a couple of years ago (perhaps with the exception of trojans, but what's the difference between a spyware trojan and a 'virus trojan', feel free to explain if you know), these days AVs are on to them. I'm talking about real-time protection here, not on-demand scans. Well, I'm having second thoughts. After all, I consider real viruses (not sure about trojans) a virtually irrelevant threat. (Are there actually 'viruses' that act as spyware ?). Over the past five years, I encountered only a handful, unlike spyware. In the past, AS' were quite effective in dealing with spyware. Typically, they were not as bloated as AV appplications. I'm really not concerned about real viruses. I'd probably be willing to ditch an AV, if I could get sufficient antispyware protection. In a way, I feel a bit stupid to get an AV just to deal with spyware. If you look at av-comparatives, that's a weak spot for most AVs. For as far as I know, there are no good antispyware applications with GREAT real-time protection, like blocking 90 % of spyware real-time (older version of the Spy Sweeper). In 'the old days', you could install a number of AS aplications (yes, all real-time) working together - if you knew what you were doing. Yes, there is Counterspy version 3. Let's just say I have my reasons for not buying it. MBAM is popular, but it is intended as a supplement for things that AVs don't catch. SAS real-time protection ? I have a couple of reasons for not adopting it 'right away'. 'lifetime license' ? That can't be sustainable in the long run. And I've read that SAS' real-time protection is not that great (poor?). In the past, I could easily combine the Spyware Doctor with the Spy Sweeper plus the real McAfee ANTIVIRUS (not the antimalware program it is these days). Later I replaced the Spyware Doctor with Counterspy 2.x, great combination. Is there any way to get first rate AS programs (more than one!) with real-time protection running, or is that something from an epoch that's over ? I'm talking about real AS applications, not about 'tech' options like LUA, SRP, Anti-Executable, Defensewall etc. The Spy Sweeper is off the table, for several reasons.
