Troyan to 77.67.4.24?

[jlgm2k]

Goodnight
The first sorry for my English.
I just installed my W7 and detect network activity.
I do a netstat and see that I have an open port, namely port 49688 and IP address 77.67.4.24.
I don´t find information about this. Is it a virus?

Hi,

For fresh Windows, network activity are legit.

Nevertheless, we can check that if you will.

First install Malwarebytes as it shall scan all your system additional for malware. Then to check if there is some leftover and full system diagnostic, I shall need logs from OTL and aswMBR.

[jlgm2k]

Thanks for you quick answer,
This is a OTL log.

[jlgm2k]

This is the aswMBR log

Hi,

Has Malwarebytes been find something? Why you did not attach MBAM log as well?

Your USB memory devices might been infected.
O32 - AutoRun File - [2009/06/10 22:42:20 | 000,000,024 | ---- | M] () - C:\autoexec.bat -- [ NTFS ]
O32 - AutoRun File - [2009/04/29 10:02:01 | 000,000,055 | R--- | M] () - D:\autorun.inf -- [ CDFS ]
O33 - MountPoints2\{38e894c0-76c5-11e3-9a4a-806e6f6e6963}\Shell - "" = AutoRun
O33 - MountPoints2\{38e894c0-76c5-11e3-9a4a-806e6f6e6963}\Shell\AutoRun\command - "" = D:\Run.exe

Do not plug/attach USB memory devices while malware check/cleaning is in progress. We shall check USB's later.

PS: Panda USB Vaccine can only protect you against USB based malware that uses autorun.inf to infect your PC. The harsh truth is that very few of malware today relies on autorun.inf to ensure the transition of the host machine. Today, autorun.inf are not the only way that malware can exploit, and therefor Panda USB Vaccine software is not compatible for USB protection.

But we'll get to that later...

Sorry for the delay,
I was traveling.
I promise that the next time I advise you.
The MBAM scan doesn´t show nothing.
I show you the log and also the ComboFix log

[jlgm2k]

Ohh.
Sorry, The ComboFix log

[magna86]

Hi,

ComboFix log looks good. Do you still have these network activity? As CF says to me "all is Ok". If you wish I can preform a deeper check but I think that it is not necessary.
