The worst malware of 2009..
« on: January 04, 2010, 02:22:03 PM »
Hi malware fighters,

The worst damaging malware for 2009 was the damaging file-infector virut, while conficker got all the attention. Also we saw a large increase of malcode injections of trusted reputable websites, there the avast shields protected our community like no other av solution could.

Rootkitted malicious software

Apart from two worms there were three Trojans seen to infest in great numbers, as there are Zbot, Bredolabs and TDSS. Last mentioned Trojan was notorious because of the used rootkit, that made removal of it very hard (essexboy and olman here on the forums know all about cleansing victim's computers of this malcreant's creation, it even defied ComboScript for a wee while).
Then some good news again the MS Autorun-patch will make it harder for worms to spread, mumber of infestation will be seen to go down Didier Stevens came up with a reg key to protect Safe Mode better and cyber criminals started to use similar social engineering tricks, making it easier for them to be identified and avoid their scams.

These were my observations. What were yours?

Cybersecurity is more of an attitude than anything else. Avast Evangelists.

Use NoScript, a limited user account and a virtual machine and be safe(r)!

Well, putting that aside, Virut and Sality are two of my best viruses^^

Best by means of infecting computers, destroying them, rendering AVs useless^^

The worse virus for me was a virus which was hidden in my pen drive's autorun.
Without any antivirus with my old pc I can say OMG because it almost infected my whole system.
Repair or removal was useless because when I did so system unbootable.
