Trojans 'confrontation' with dangerous software

Source: PC World

A "civilian" Trojan is likely to want to protect computer systems from the effects of viruses every time users enter peer-to-peer (P2P) networks.

After getting into the PC, Trojan Erazer.A will search for the default directories that the P2P program still uses to download MP3, AVI, MPEG, WMV, GIF, Zip files and wipe out all data with the extension.

Because the Trojan only deletes certain types of files in specific directories, network security experts say Erazer.A is trying to protect the systems it has penetrated. British security firm Sophos calls it a "civilian" Trojan because this type of software is very rare and anyway, it offers some benefits for users.

However, Erazer.A also caused problems with programs that kill viruses and steal information. " I don't think Erazer is dispersed with good intentions because it tries to turn off security. It's dangerous if people think there are viruses written to protect them because that will create a misconception. "Who knows what will happen to the next versions of Erazer B, C, D . " said Sophos adviser Graham Cluley.
