Threat Details:
Categories:
trojan
Description:
Bancos.prx pretends to be a harmless file like a picture to get executed. It connects to its malicious servers in background and tries to hide as a Windows system file to compromise the computer. It also uses the Internet Explorer to secretly contact its malicious servers and accquire banking data.
Removal Instructions:
Autorun:
Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd), RunAlyzer (http://www.safer-networking.org/index.php?page=runalyzer) or msconfig.exe to remove the following autorun entries.
Entries named "svchosts" and pointing to "C:\WINDOWS\system32\svchosts.exe".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
A file with an unknown location named "imagem.exe".
The file at "c:\A3.0.txt".
Make sure you set your file manager to display hidden and system files. If Bancos.prx uses rootkit technologies, use our RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!
Registry:
You can use regedit.exe (included in Windows) to locate and delete these registry entries.
Remove "<regexpr>http://[a-z] \.com/thumbnails/[a-z] \.pac" from registry value "AutoConfigURL" at "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\".
If Bancos.prx uses rootkit technologies, use our RegAlyzer (http://www.safer-networking.org/index.php?page=regalyzer), RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
Final Words:
If neither Spybot-S&D nor self help did resolve the issue or you would prefer one on one help,
Please read these instructions (http://forums.spybot.info/showthread.php?t=288) before requesting assistance,
