The newest update from BitDefender shows little change in its most infamous position: top of the monthly e-threats report.

That is because Trojan.Clicker.CM continues to be the most widespread piece of malware currently infecting computers across the world, with its actions underlining the importance of having disaster recovery or online data backup in case things go awry.

BitDefender explained: "This threat is present on websites hosting illegal applications such as cracks, key generators and serial numbers for popular commercial software applications. It is typically used to force advertisements inside the browser."

Trojan.AutorunInf.Gen came second, a generic mechanism which regularly spreads malware through the use of removable devices including memory cards, flash drives and external hard drives.

The well-known Conficker worm came third under the official title Win32.Worm.Downadup, which restricts use of IT security vendor websites while also installing rogue software on infected machines through its latest evolution.

Today (November 4th), the FBI's cyber crime experts warned that many banks are being targeted by hackers attempting to siphon funds through the use of malware.

New research from Connect found that, on average, it takes businesses that use backup tapes take 11.6 hours to retrieve and restore files. Connect is now recommending that SMEs switch to online backup.
