Chrome has a trojan?

Viruses and worms
1

Well hello there!

Since last time I got some great help here, I get back to you…

This morning I tried to open Google Chrome Browser, but avast detected a Trojan… JS Downloader-ZY

It is detected in the file: C:\Program Files (x86)\Google\Chrome\Applications\chrome.exe

It’s true that recently, on Chrome I’m being redirected to PC Virusscan online-websites and sites like paltip.com

I’m scared to put my USB in my PC and it will get infected, since I’m busy with my thesis…

I have a windows 7 64-bit system btw :slight_smile:

Can someone please help me with this?
Last weekend I did a Malwarebytes scan and nothing was found…

Attach your logs. (MBAM, OTL and aswMBR…!!)
Instructions: http://forum.avast.com/index.php?topic=53253.0

Attached you will find the 3 logs. I hope someone can look at this? For the moment I’m using Mozilla Firefox and thank God all my files have been uploaded through Dropbox, so they’re safe.

Could you let me know if this stops the alerts

Here they are.

I see that many annoying things have been deleted such as similarsites & co. I never knew how to delete them!

Thanks in advance!

Have the alerts now ceased ?

Yes! Thank you Essexboy! I really appreciate your help!

One little question, how do I delete all the programs used? OTL, aswmbr and AdwCleaner?

8

Essexboy will remove them when you say so … when he is back online :wink:

In that case methinks I will send you on your merry way :slight_smile:

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Download and run Delfix

: Keep Java Updated :

WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article and this article.
I would recommend that you completely uninstall Java unless you need it to run an important software.
In that instance I would recommend that you disable Java in your browsers until you need it for that software and then enable it. (See How to diasble Java in your web browser and How to unplug Java from the browser)

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

CryptoPrevent install this programme to lock down and prevent crypto ransome ware

Malwarebytes.

Update and run weekly to keep your system clean

It is critical to have both a firewall and anti virus to protect your system and to keep them updated.
