My daughter's computer is infected by AntiMalware Doctor. When the computer is booted AntiMalware Doctor appears on screen and one can click through various sub-screens that come up. However clicking "no" always brings up yet another AMD box. It is impossible to access any other part of the computer as none of the icon buttons will work. When I try crt-alt-delete and then open Task Manager I get a box that says:
------
Antivirus Software alert (in red)
INFILTRATION ALERT Virus Attack
Your computer is being attacked by an internet virus. it could be a password-stealing attack, a trojan-dropper or similar.

DETAILS

(Blank lines)

Do you want to block this attack?

Yes No
---------
The "No" button seems inactivated, leaving the "Yes" button coloured and ready to click - except I haven't done that.



There are also other AMD boxes that come up saying things like:
-----
Security warning

Application cannot be executed. The file taskmgr.exe is infected. Do you want to activate your antivirus software now?

YES NO
---

Every time I click "No", the same screen comes up but with another file listed as the infected one.


I cannot get any other icon button to fucntion on the screen.

I think the computer uses Windows XP . We use Firefox as browser.

I've found out that AntiMalware Doctor is a rogue program but the solutions offered all require me to get INTO the computer and at present the rogue program is not allowing this.

I'd be grateful for assistance in getting rid of this rougue program as my daughter is in her last year of high school and needs a functioning computer for her study.

Thanks in anticipation!

Let's see what we can get here.
Please follow our Removal Guide here Remove Antimalware Doctor . You will move to the Automated Removal Instructions

After you completed that, post your scan log here,let me know how things are.

Hi and thank you! I have followed all instructions and Malwarebytes found bad files and I deleted them and restarted the computer. It seems to work except the Windows display is odd - no open program shows up on the taskbar and I can't seem to fix that. So if I change from one "open' program to another and then want to go back, I have to click the icon on desktop and it re-opens the program - especially annoying for Firefox. I'm not sure what I have done for this to happen?

Here is MBAM log:

Ok good.. now run SAS and see if the display is back to normal.

Then press enter on your keyboard to boot into Safe Mode

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.

Sorry! I went down with flu and am only just recovering. It will be a few days before my brain works well enough to follow your instructions but I very much appreciate your assistance and will try and implement it all once I recover.

Hi Boopme!

I'm back on my feet and just as I was thinking I had better go and follow your second set of instructions on my daughter's computer, she came running in to tell me it had another virus! Arrrgghhhh!!

Well I found that it was actually ANOTHER rougue virus protect program - this time Antivir Solution Pro. So I printed off and followed the removal instructions on this website. Then I went on and followed your second set of instructions above. The only snag was when SAS finally finished and I ticked REBOOT, it ended up frozen on the safe mode screen (black with safe mode in white in each corner plus the Windows version written accros the top of the screen). I had to turn the computer off at the switch and then reboot.

The good news is that the computer seems fully back to normal - the open programs show on task bar again!! Whoopee!

THANK YOU!!!!!! Do you advise that I purchase Malwarebytes Pro for my daughters' computers? I'm not sure they remember to update each day and at 17 netsurfing is a favourite sport! Or will SAS now prevent this sort of malware attack? Any other precautions to avoid further trouble in the future?

Again thank you so much - and thank you to this website!

Liora

Hello Liora :thumbsup: , yes the purhase provides the active protection and iupdates for both tools.
What antivirus app is installed.?


If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:
