avast! failed to detect a threat while TrendMicro won… see the attachment

2

send the files to virus@avast.com via mail.

The files you are talking about are harmless.Its a gamurue worm payload.So if avast blocked the main worm autorun file and the executable.Thumbs.db is just harmless on its own.

Everyday 22,50000 or more pieces of viruses come out…no AV is 100% everything depends on your browsing habits and the way to work.Dont blame a AV.Every AV is statistically effective.It depends on which av protects A individual with bad browsing and no caution rather than B individual with the same AV and good habits.Always ask the person you are taking a USB from.Since you live in india alot of noob AV users are out there like quickheal and NPAV which are no better than crap.

And your problem is… ?

And where are the details?
What os/sp?
What exact version of avast?
What settings? (e.g. pup detection, scanning all files enabled or not)

There are also things avast detects while trend doesn’t.
Same is true for any av.

Are you running multiple av’s on the same system?

It may be harmless…but it hide all files in my pen drive…that is a harm to me…! After TM removed it my files returned

5

Install MCShield. www.mcshield.net

6

I’m using only avast…scanned my pendrive in another pc with TM

7

Install MCS, plug in your pen drive and be surprised. :wink:

8

Any compatibility problem between avast! and MCS ?

9

None at all they are complimentary

Then ok…installing right now…thanks…

Pondus, here is the scan log…!! MCS found other threats which TM missed!. (What means I:\autorun.inf > Suspicious > Renamed. (MD5: d41d8cd98f00b204e9800998ecf8427e) )

12

Why dont you just send all the infected files to virus@avast.com.Just zip the files up and password protect them and mention the password in mail body…

It worthy job done rather than complaining here ::slight_smile:

I:\autorun.inf > Suspicious > Renamed. (MD5: d41d8cd98f00b204e9800998ecf8427e

autorun.inf are just a trigger file, file that telling Windows to launch other executable file. In most cases, the executable file is some kind of installer.

Example:

http://media.downloadblog.it/a/aut/autorun_02.gif

This autorun.inf want to tell Windows to launch installer for Macromedia_Setup.exe

Open the detected autorun.inf (it is called now as autorun.inf.blocked) using notepad and see on witch file is targeting.
In any case, without some logs we can’t tell you much.
