why windows media player ?

why windows media player ?

I uploaded the log for analysis and the location of the file was highlighted as suspicious.

http://www.hijackthis.de/

http://www.sophos.com/security/analyses/viruses-and-spyware/trojpsymeat.html

Malware sometimes pretend to be a legitimate file, so it was worth checking out.

Nothing else looks suspicious, but Vanti is a rootkit so it may be hiding.

What alerted you to Vanti?

Do you have version 4.8 of avast! (The lastest version.) If you do, have you tried a boot time scan? This will also run an anti-rootkit scan.

Right click the scanner screen, select ‘schedule a boot time scan’ and reboot when requested.

Try a scan with DrWeb CureIT!

Try one or more of these anti-rootkit scanners if you’re still having problems.

Panda Antirootkit
Blacklight
Trend Micro Rootkit Buster
McAfee Rootkit Detective
Sophos AntiRootki

Yes the vanti I lerned of it from avast and I got the latest version, I have done the boot scan but that dose not help, I wil continue whith the help you give me until I find a solution

These posts may have some bearing:

http://forum.avast.com/index.php?topic=35895.0

http://forum.avast.com/index.php?topic=35692.0

I’m not sure if it’s a false positive or a rootkit modifying legitimate files.

???

Hi,

I don’t know much about this and I’m not done yet, but when the Vanti virus showed up on my computer after I borrowed a pen drive I got good advice from Polonus here to run Dr. Web Cure It. Vanti did not show up; “Besso”, a trojan, showed up, in 19 files including system restore.

However, after Dr. Web Cure it moved these files, I stopped getting that Avast Alarm every time I turned my computer on. So I tend to think they are related…

Hope you can get to the bottom of it!

11

have anyone sent a commented sample to virus[at]avast[dot]com? i don’t know if it really is a false positive (it would be reported by many users) and can’t tell you more without having seen the file… i will be offline this weekend, so i can’t do any direct action immediately… anyway, it’s strange, that the file is detected on the machine and not at virustotal… it’s a detection independent on anti-rootkit engine…

12

I thank a lot I believe I got rid of it and was done with DoctorWeb.

The thing is that I get this mesage wen I doble clik on one of my hard drives. so I can only acces my information with one of my short cuts.

The mesage is that of wich one gets wen triying to open an unrecognisable file.

Can this be caused by a virus ???
