Hi The Zodiac,
It was discussed before here & in other places few (if not many) times
Having AV in place I haven't used full scan for about 4 years ever
(only for testing purposes sometimes)
Comodo's AV was created for a “convenience”/ “usability”, as Melih said, for having a Suite
Whatever “usability” means... For me – it means nothing – use other AV that has much better detection rate & less FPs, or don't use any
Having decent Behavioral Blocker is more efficient anyway
But in this case Comodo was most likely correct – not a malware
According to my research more than 80- (90%?) of “keygens” are never malware
a bit less % , but the same with cracks – many are as clean as well filtered water!
As it was pointed - the vendors just go into P2P sites; gathering them and adding to the signatures
I'm not saying that you cannot catch the bad one” - risky stuff ! It is your choice whether you wanna research
The contributors are not only hackers/crackers, but the major players – the big companies that are protecting their Software.
They are substituting downloads of perfectly made cracks. Believe me – they have special forces / agencies for doing that.
That doesn't mean that I am supporting piracy … do not get me wrong, but just collecting anything out there and adding to the signatures doesn't do any good as well
Sure languy99 is right
...Also I don't know how much research you do concerning CAV detection ratios, but I find malware everyday and it does find a significant amount of malware, maybe you have just not checked enough of them.
Please check if you want … but check thoroughly
If you are advantageous enough...

you will find out that what was flagged by many security as a malware (especially keygens) will work perfectly after you would a set up the Software.
Password protect cracks/keygens & test the System & Software after the installation... how may “Trojans” and nasties you will find ?
From my experience MSE jumps before D+ (and only MSE, no D+ as well).
I wouldn't use Comodo's AV; I just don't trust it.
Well ... I am not using neither MSE nor Comodos AV ... but if you are talking abut trust - I would rather use Comodo's Av than MSE
Cheers!
p.s. using abbreviations like"WTF" is not nice thing to post...
anyway... recently here in the forum the "decision" was made that WTF stands for "
