Hello all at wilders', I really had to make up this little report. I fixed a friends computer today, and had a very interesting experience. Too bad I couldn't take any logs or screenshots with me, so I'm sorry about that. Case: Heavy infected system, bootup problems ect. ect. Solution: First solution: McAfee, found several worms and trojans (Netsky, Mytob and SDbot). Second solution: F-Secure, found one trojan (SDbot) McAfee left behind. Thirt solution: Symantec found 218 (!) infected files the left behind. A couple of them were in the Windows folder, others in his Mozilla Mail archive. Conclusion: Was very suprised by this. And it made me think of the quality of the other two products, 218 is a lot. And it were all quite old variants of Netsky, Mytob and some SDbots. So at the end I've to admit, Symantec really has good detection, and for some reason also good unpacking (considering the viruses it found in the mail archive). I've submitted the missed samples to both F-Secure and McAfee.
