I downloaded the newest Avast a few days ago and now every time my computer boots I get a warning about a virus being moved to the chest. It's identified as Win32:Malware-gen. It doesn't show up when I do a boot scan though.
I've run the scans in the pinned topic and attached the logs. Is there anything that can be done?

All looks just fine.
I downloaded the newest Avast a few days ago and now every time my computer boots I get a warning about a virus being moved to the chest. It's identified as Win32:Malware-gen.
Do you still getting these warnings?
If you do, can you tell us the exact name with path of detected file?
Also, could you go here:
C:\ProgramData\AVAST Software\Avast\report
...and attach here "BehaviorShield.txt" log
-
No warning when I booted up just now.
The path was C:\Users\Dave\AppData\Local\Temp but the name was always different. The last few names were iefgtvgj.dll c4ygo0pm.dll ub4wuz1j.dll.
-
This is %temp% folders. CF is automated to deletes the contents of those folders.
It is necessary to uninstall ComboFix :
- Click Start (or (http://amf.mycity.rs/pg/images/VistaStartButton.png)) then Run.
On Windows7 or Vista you may use Start Search field if Run is not available.
- In the line of text type in (Copy) the following:
ComboFix /Uninstall
Note that there is a space between " ComboFix " and " /Uninstall " .
- then click OK (or press Enter ).
Wait for the uninstall process is complete.
We will keep other tools and let me know tomorrow how your computer running.
-
Unnistalled, I'll let you know tomorrow. Thanks for the help.
-
I've booted up a few times since yesterday without any issues.
I assume I should change all my passwords just to be on the safe side.
-
:) Will remove the used tools.
Please download DelFix (http://general-changelog-team.fr/fr/downloads/finish/20-outils-de-xplode/9-delfix) by "Xplode" to your Desktop.
Run the tool and check the following boxes below;
- Remove disinfection tools
- Create registry backup
- Purge System Restore
Now click on "Run" button. Wait for the programme completes his work.
Tool will create and open an log report (DelFix.txt)
Note: The report will also be stored on C:\DelFix.txt
> I don't need DelFix log report.

I recommended to keep Malwarebytes and to use MCShield if you will.
You may download MCShield from one of the following links:
MyCity - Official download link (http://amf.mycity.rs/mcshield/)
Softpedija - Mirror download link (http://www.softpedia.com/get/Antivirus/MCShield.shtml)

And not only will prevent infection, but it will immediately clean flash drive, memory card or external HDD.

All done, thanks.

Hi,

As it says this is virus chest. You don't have to worry about, nothing can escape from there.
Or...you can empty virus chest if you will.
Also do u know what could be that file ?
Nothing, location points to system %temp% folder where various program place its temporary files during installation or some running.
As there are malware that know to use %temp% as loading point avast know to flag this junk files. TFC cleans all temp files.
Can you please help me again ?

Only one of them will run on your system, that will be the right version.
- Double-click to run it. When the tool opens click Yes to disclaimer.
- Press Scan button.
- It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
- The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.
Next...
Please download GMER, the RootKit Detector tool from the link below and save it to your Desktop:
Gmer download link (http://www2.gmer.net/download.php)

Double-clicking to run GMER.
- Wait for initial scan to finish - if there is any query, click No;

You are malware (http://en.wikipedia.org/wiki/Malware) free. Posted logs are now appear cleans and show no signs of active infection.
Good workman always cleans up after himself.
• The following will implement some post-cleanup procedures:
=> Please download DelFix (http://general-changelog-team.fr/fr/downloads/finish/20-outils-de-xplode/9-delfix) by Xplode to your Desktop.
Run the tool and check the following boxes below;
(http://www.mcshield.net/personal/magna86/Images/checkmark.png) Remove disinfection tools

--- --- --- --- --- --- --- --- --- --- ---
• To help AntiVirus to protect your computer and speed it up, I recommend that you download, install and keep the following free programs:
1. Keep Malwarebytes Anti-Malware (http://www.malwarebytes.org/mbam-download.php), update it regularly or from time to time and run a Quick Scan weekly.
Malwarebytes will detect and remove all traces of known malware. MBAM isn't AntiVirus and it can NOT replace it.
2. Keep MCShield Anti-Malware (http://www.mcshield.net/downloads.html), the tool will be updated regularly and perform auto-checking for malware to each attached USB memory device.
MCShield, has been designed as a lightweight scanner that's smart enough to catch even new worms and work in fully automatic removal mode.
3. It’s recommended to delete Temporary Files every once in a while. Run the tool and click on the Start button and TFC will begin to clean. Then restart the computer.
Temp File Cleaner aka TFC by OldTimer (http://www.geekstogo.com/forum/files/file/187-tfc-temp-file-cleaner-by-oldtimer/)
TFC is small & usefull utility that shall clean up temp files from all userprofiles and system folders.
--- --- --- --- --- --- --- --- --- --- ---
• How to protect yourself?
- I recommend that you use one of the fantastic opportunities provided by (http://www.mcshield.net/pg/images/avast5.png) avast! 2014.
1. Adjust avast! to target PUP (http://computersecurity.wikia.com/wiki/Potentially_unwanted_program) software:
Run avast! 2014 by clicking the system tray icon in the lower right corner of the screen.
Click on Settings, in the new window that opens, click on Active Protection, then under File System Shield click on gear wheel...
Under Sensitivity part of option check box for Scan for potentialy unwanted programs PUP.
2. avast! Software Updater. Run avast!, click on Tools > Software Updater.
For security reasons, make sure you do update your browser(s), Java, Flash Player, and basically every software you use often.
3. avast! Browser Cleanup. Run avast!, click on Tools > BrowserCleanup.
Browser Cleanup tool is an integrated tool in avast! AV that allows you the control on browsers unwanted addons.
