Re: malware threats

What your seeing is called Adware, they are trying to make you think you are infected to buy their software to remove it.

What you need to do:
Go to a reseller of AVG, download the software and run a FULL scan once complete delete the threats its finds.

How to remove win32/mebroot?

Hi there,
Well this Win32/mebroot is a trojan and you need a trojan killer to remove this. you can remove this by two ways -
1. Online - means when your computer runs the operating system and you can install the trojan killer and search for the trojan.
2. Offline - in this you don't need to start the operating system of your computer, you just need the offline CD of a trojan killer that starts automitally before windows start and then you just make a search for the trojan.
Please follow the below link to get your trojan killer -

Good Luck

You have a Backdoor Trojan present on your pc
A Backdoor is a software program that gives an attacker unauthorized access to a machine and the means for remotely controlling the machine without the user's knowledge. A Backdoor compromises system integrity by making changes to the system that allow it to by used by the attacker for malicious purposes unknown to the user.

They are typically installed without user interaction through security exploits, and may allow an attacker to remotely control the infected machine. Such risks may allow the attacker to install additional malware and use the compromised machine to participate in denial of service attacks, spamming, and bot nets, or to transmit sensitive data to a remote server. The malware may be cloaked and not visible to the user. These risks severely compromise the system by lowering security settings, installing 'backdoors,' infecting system files, or spreading to other networked machines.

If your computer was used for online banking or has credit card information on it, all passwords should be changed immediately to include those used for email, eBay and forums.
You should consider them to be compromised.
They should be changed by using a different computer and not the infected one,if not an attacker may get the new passwords and transaction information.
Banking and credit card institutions should be notified of the possible security breech.

Since your computer was compromised read:

Spyware Protection screens keep popping up; saying that the computer is infected with different Trogans and viruses....and also requesting that you activate Spyware Protection to protect your computer. ...

Take note of the exact message you are getting and, preferably on a different computer, enter that message in a search window inside of quotes. The message you are getting is FROM the Trojan; you are already infected and you will need instructions on the removal. Entering the precise message will most likely identify the specific Trojan you have. Worst case, you may have to format your hard drive and re-install the operating system.

Well, What's a backdoor trojan? If i restarted or restored the pc

A backdoor trojan is a bad. They are a sort of virus with the capability of sending information back to the controller of it. It can be downloaded and can turn on without you knowing it and then it will follow whatever instructions it is given. The information it can send out is worse than any damage it does to your system. Passwords, bank info, credit card numbers. It can even email your contacts using your account.

System restore does record and copy these, and you need to turn system restore off during your scan and removal process. System restore does not allow virus software to remove these files.

First, update your virus program and then turn off your internet connection. Then turn off system restore by going to your control panel>System>and then click on the System restore tab, usually in the back. Close those windows and and start your virus scans. Follow the instructions after it locates the virus. If you have the option of deleting the virus, do that rather than put it in quarantine.

Since you have a program running that you don't even know about, it can certainly put a drag on your system and slow things down. Your Windows OS is so old, I can't believe it is still running. Congrats, everyone I know had a fatal crash by this time. If you need further help, please leave a comment. Thanks for your question.

Msa.exe has stopped working and trojandownloader:win32/renos.js keeps popping up and I cant remove it or find what it is. How do I stop the problem?

This is an indication of malware that has been installed onto your computer. Please follow the steps outlined in this malware removal guide to safely scan your system with MBAM and remove the trojan.
Also be advised that service pack 3 includes many security upgrades and patches for xp, and you would be better protected by installing it, if you are indeed still running only with sp2.
For more details about msa.exe see here.
For more info about the trojan see here.
If you prefer to create a post and get expert guided assistance in the removal of the malware, please choose one only from the list of malware removal sites in the last part of this post., then follow through until you are given a clean bill of health.
If you do not have a good antivirus program running on your system, or yours has allowed this infection to be installed, I recommend you look into Avira or Avast. They are both free and reputable.
Good luck.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

My AVG cant remove a Trojan horse -how can I get rid of it?

well be glad i saw your problem, coz we're gonna fix it for ya. Keep in mind you are going to have to install some new software and be patient, this will take a bit of your time.

Step 1.

a lot of people don't realize that over 90% of Trojans write themselves into your system restore function. So the first thing to do is disable your system restore.
To do this:
1. Right click on My Computer / properties
(this will open your system properties)

Click on the System Restore Tab - now check the box beside "Turn off System Restore on all drives"
Press Apply then OK

The Software you need to Download:
Go to
search for SpyBot Search & Destroy & Malwarebytes' anti-malware, Also Download CCleaner.
now download and install all programs.

Now update all applications

Now lets reboot into "Safe Mode"
For most computers Hit Start / turn off computer / restart - as soon as computer boots press F8 (you can check the safe mode boot up procedure, (Start/ Help & Support / search for safe mode)

When the Safe Mode screen starts select "start in Safe Mode"

When windows loads up completely hit Start then start spybot search & destroy and follow the directions to begin the scan. Do the same for Malwarebytes' anti-malware.

Let the scanners run their course then remove anything that is found. SInce you are in safe mode it should remove everything with no problem.

Now lets Reboot into Normal windows. Then lets run the CCleaner Program. The first Tab on the left reads "cleaner" and has a brush on it. Select that tab, on the bottom right click run cleaner.

Now when that finishes select Registry Tab on the left. then select Scan for issues. When scan has finished select "fix selected issues" it will ask you if you want to backup Registry, say no, then press fix issues, then close. Run registry cleaner till nothing else shows up.

You should be ready to go now, virus free. To make sure rerun all the scans we did previously. If their are some issues that could not be removed you will be notified (these are normally registry entries) you will then be asked if a scan can be performed at the next boot. Select yes on one or both of the programs ( spybot and antimalware's). then immediately reboot.

I hope this helps fix your issues. Please rate very helpful if this fixes your isues. ^_^ thank you
