Title: Avast Pop-ups won't stop after plugging in flash drive
Post by: Fireforgey on May 07, 2014, 08:18:40 AM
Hi guys, I need help.  Ever since I put in a few flash drives into my computer (I know I know, but I had to do it) Avast keeps popping up every 5 seconds with two notifications:

Avast Web Shield has blocked a harmful webpage or file.

Object : http://www.weebly.com/uploads/28/1/0/28102339/ahpaa.exe
Infection: URL: Mal
Process C:\\Windows\System32\wscript.exe

And Another exactly the same, but with a different Object:

Avast Web Shield has blocked a harmful webpage or file.

Object : http://www.weebly.com/uploads/28/1/0/28102339/22.exe
Infection: URL: Mal
Process C:\\Windows\System32\wscript.exe

So far, I'm doing a full system scan with Avast, did a full system scan with Malwarebytes (got rid of quite a few things but it didn't solve the problem) and I'm quite lost as to what to do.

Please help.

Edit:
Am currently uploading the files, but it said that asw doesn't work on Windows 8 which is the system that I'm using.  Is that ok?  There other scans will be uploaded in a few minutes once scanned.

Well, first of all, that you all so much for all of your help.  Getting rid of this virus almost feels like a job...and I'm just following a couple of instructions.  On a positive note, the AVAST pop-ups have stopped, however I noticed something interesting.  Every-time I turned on the computer, two cmd.exe windows would appear and disappear. Now, they stay because a command box opens saying that it can't find C:\Users\Omar Eldahan\AppData\Roaming\asadfkjowea.exe or something like that.  I've attached the scan logs that you asked for.  Enjoy  ;D.

Ok, well I did as you said and everything seems to be fine.  The cmd.exe windows stopped appearing.   However, I have a few questions.  first of All, the MCShield said that their were suspicious files on my flash drive and that it "renamed" them. Does that mean it fixed them?  Also, which of these programs that I downloaded should I keep, and which should I get rid of?  Huh, this experience has been kind of depressing.  I usually consider myself to be pretty good with computers, and yet I do not have the slightest clue as what I've done; it seems to have worked though. Hats off to all of you.

MCShield basically made them inactive due to renaming.  Keep MCShield on your system to protect you from bad flash drives, it uses no resources

All that was done was the run entries/startup entries and associated files were deleted

Subject to no further problems   :)

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 (http://general-changelog-team.fr/fr/downloads/finish/20-outils-de-xplode/9-delfix)

(https://dl.dropboxusercontent.com/u/73555776/delfix.JPG)

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

CryptoPrevent (http://www.foolishit.com/vb6-projects/cryptoprevent/) install this programme to lock down and prevent crypto ransome ware

(https://dl.dropboxusercontent.com/u/73555776/CryptoPrevent.JPG)

Malwarebytes (http://www.malwarebytes.org/mbam-download.php).

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.

To learn more about how to protect yourself while on the internet read this little guide  Best security practices  (http://www.bleepingcomputer.com/forums/t/407147/answers-to-common-security-questions-best-practices/)Keep safe  :wave:
