Sorry, I know Avira is a respectable and reputable security company, but they have joke products and it's been this way for a long time now. I agree with
@XIII and
@SHvFl (by the way I almost died laughing while reading the part about their "precious" signatures).
They need to step up their game and focus more on the dynamic aspects of malicious software protection, as opposed to keeping their focus directly on static detection methods - such as signature-based detection through checksum signatures - which are getting more and more obsolete everyday through the usage of zero-day packing techniques and even .NET obfuscation methods.
It seems they have an outdated engine and an outdated GUI - by "outdated" I am referring to it not being modern - since modern protection engines these days include really good dynamic heuristics, sandboxing, BB/HIPS protection mechanisms...
I know some people may not like what I am about to say, but I find it lazy and completely ridiculous that they have fallen behind with all the money they make... Many people use Avira, they surely have enough to invest in development of more sophisticated behavioural components. In fact, they don't even need to necessarily invest money, they can just do their own research on malware analysis and apply some basic concepts they should already know to develop at least a basic HIPS engine.
Hopefully Avira see this and take these points on-board, they are wasting too much time focusing on their signatures and their speed-up optimisation software/software launcher (they need to completely ditch the optimisation software and the launcher since it wastes their resources and is starting to ruin their image a bit IMO), when they could be spending more time on what really matters these days.
