Trojans are a threat to users

In August, users faced 7 new threats from garbage Trojan Horse's with 10 regular dangers, a security company announced on Friday.

According to Sopho statistics in the UK, malware appeared in the past month with 71.8% of the Trojan's new malicious code. The company has been poisoned by nearly 2000 new documents in August.

Opponent McAfee also confirmed that the Trojans' current trend is one-off, not self-replicating or poisoning other machines via e-mail. Traditional types of worms are decreasing.

Not operating in a slow way of spreading like traditional worms, the new Trojan has an increasing level of vandalism with a 'large, short-time' campaign. ' Junk programs using this Trojan appear only for one day, or at most two days, ' said McAfee in a recent online study. ' This makes the spammers have enough time to access countless emails and just enough time before the anti-virus software is released. Antivirus vendors are now able to provide a trace of this new type of Trojan . '

McAfee highlighted three Trojans: Yabe.r , Dloader.dhx and Haxdoor.il and illustrated their rapid production and removal diagrams. From the diagram we will see the speed of the distribution of these Trojans increasing. The first Trojan spread in two days, 4-5 months. While the following Trojans only came and went inside for a day.

' Junk mailware is currently the most common risk ,' McAfee said. ' Since a large number of mailers are now down, let's wait and see more and more Trojans appear .'
