False positive?

[stinker]

I have reason to believe I have a false positive on my hands. Literally every week I do a quick scan with malwarebytes and I keep finding at least 1 new virus in my temporary internet folder. Soon after finding these virus's and deleting them I do a full system scan after my computer has Re-booted, and it turns up nothing. Here is one of the malware bytes scans that I have saved.

Can you unquaritine this file and zip and attach to this post please?

Thanks!

[stinker]

sorry, I deleted it from my quarantine... but if another one pops up i will....

[shadowwar]

Ok need to see the file to go further with this.

Thanks!

[stinker]

ok, did another scan today and found a trojan.agent in another temp internet folder

It would be helpful if we could see these scan logs. Detections in temp directories could easily be parts of blocked infections but without a log or samples there is no way for us to check.

[stinker]

here is the log from the trojan.agent and i have the file in quarantine how would i get it our of quarantine and give it to you guys (I'm new to this)

Here are these 2 infected files

38aace64-3b202c4f.zip

2592d15a-26a25622.zip

[nosirrah]

Both files are malicious. It appears that you are doing a LOT of dangerous surfing and/or have outdated web facing software that is wide open to exploits and/or you already have a bad TDL infection.

I am asking support to take a look at this.

Here are the steps needed to get your computer cleaned....

Please read the following so that you can begin the cleaning process:

You have 3 Options that you can choose from as listed below:

• Option 1 —— Free Expert advice in the Malware Removal Forum
  
• Option 2 —— Paying customer -- Contact Support via email
  
• Option 3 —— Premium, Fee-Based Support

OPTION 1

As we don't deal with malware removal in the

General Malwarebytes' Anti-Malware Forum

, you need to start a topic in the

Malware Removal forum

so a qualified helper can help you fix any malware related problems/infections you may have.

• Please read and follow the
  directions here
  , skipping any steps you are unable to complete. Then post a
  NEW topic here
  .
  
  
• After posting your new post, make sure under
  options
  , you select
  Track this topic
  and choose
  Immediate Email Notification
  , so that you're alerted when someone has replied to your post.
  
  
• One of the
  expert helpers
  there will give you one-on-one assistance when one becomes available.
  
  
• Please refrain from making any further changes to your computer such as (Install/Uninstall programs, use special fix tools, delete files, edit the registry, etc...) unless advised by a malware removal helper. Doing so can result in system changes which may hinder the attempts by a helper to clean your machine.
  
  

NOTE:

Please DO NOT post back to (bump) your topic within the first 48 hours.

Replying to your own posts changes the post count and helpers are looking for topics with zero replies. If you reply to your own post helpers may think that you're already being helped and thus overlook your post.

• If there is no reply from any experts after 48 hours, you can reply to the topic, asking for help again.
  
  
  Or
  
  
• You may send a Private Message to a Moderator asking for assistance.
  
  

OPTION 2

Alternatively, as a paying customer, you can contact the help desk at

support@malwarebytes.org
