Malware: Random ads playing

I'm running Windows 7 and started getting random ads playing in the background and random intervals. I've run the McAfee Anti Virus scan and it did find some Malware. Once the malware was removed, a window started opening stating that there was something not compatible with IE. I made the mistake of viewing the message and the sounds started again.

Bottom line, even if McAfee is able to find the offending Malware, I still get the stupid window saying that it can't run. How do I eliminate everyhing about the virus? Has anyone seen a resolution?

Re: Malware: Random ads playing

Could be that whatever it is doing this is classed as Adware by McAfee (and so might not be deleted automatically).

Try running Malwarebytes and see if that clears it.

Also try the scans in safe mode.

Re: Malware: Random ads playing

It is a Boot Sector Virus. Your computer MBR (Master Boot Records) is infected.........

To fix this one you have to fix the MBR........

If you are using a Windows XP then you can use this Tool to fix the MBR

  This tool will work in Windows Vista and 7 also. If you are facing any problem after a restart you need to do the following steps also.

  

If the Tool Crashes the PC

To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:

    Put the Windows Vista or Windows 7 installation disc in the disc drive, and then start the computer.

    Press a key when you are prompted.

    Select a language, a time, a currency, a keyboard or an input method, and then click Next.

    Click Repair your computer.

    Click the operating system that you want to repair, and then click Next.

    In the System Recovery Options dialog box, click Command Prompt.

Re: Malware: Random ads playing

@kuttus, in the line "If you are using Windows XP...." you recommend a tool published by a direct competitor to McAfee which is against forum rules.

Whilst your help is appreciated might I suggest specialist advice such as this be given via private message or other means such as an email exchange, by prior arrangement with the original poster of course?

Such tools really should only be used under the supervision of a professional anyway and posting detailed instructions like this here could lead some of the more inexperienced users into more problems.

In this particular case I'm curious as to why you decided this is a boot sector virus?   To me it sounds more like good old-fashioned spyware.

As the OP hasn't posted back it looks like the problem may have gone away anyway but it would be nice to hear back from them.

@Squint23, there are a number of tools listed in the last clickable link in my signature if needed, including some approved 3rd party ones.

Hi Ex_Brit

I am working as a Virus Removal Technician for one Antivirus company. For  that last few months we are getting this similar cases. In all those cases the reason for this infection is a MBR infection.  The main reason I suspect this as a MBR infectiom.

Thank you.

Re: Malware: Random ads playing

Ah, I wont ask which company.      Just be careful recommending competing products.  McAfee usually has their own set of tools.

Thanks.

I don't know much about their technical details but this is McAfee's Free Tool page:  http://www.mcafee.com/us/downloads/free-tools/index.aspx  

Many of the sections are really for the Enterprise/Business sector.

Plus I have a list of some plus approved 3rd party ones in the last clickable link in my signature below.
