I just reinstalled Windows 7 from the recovery partition on an Acer Aspire AX1430-UD30P. I then ran a complete virus scan using the latest version of Microsoft Security Essentials.

It found a serious threat: a trojan virus apparrently infected the Acer games that were shipped with this desktop PC. MSE said that it cleaned the virus when I clicked for it to do so.

I have screen captures if anyone would like to see them.

Be careful out there.

    You probably still have a rootkit (MBR infection).....

    I'd use diskpart clean, and then reinstall my recovery software that I purchased from AcerStore.

    Edit:  I doubt that your computer was shipped with a virus.  Just because your recovery partition *might* be infected...doesn't mean that your computer was shipped with a virus. I don't know if it's even possible to write data to a recovery partition. I suspect the root cause of your problem is a MBR infection.  When you reset your PC to factory defaults (like you did), it doesn't fix the MBR.  So you still have the same old infected MBR.

     

    One of the reasons that newer computers with UEFI and secure boot are so nice is you generally don't have to worry about stuff like that anymore.  Legacy MBR is pretty susceptible to really bad viruses....that are hard to get rid of. You have to use diskpart clean or diskpart clean all.

     

    A less effective method is bootrec.exe /fixmbr from an admin command prompt.....and then running a full scan afterwards.

    i agree with JordanB, 100% sure that your laptop was clean from factory or the web will be full of threads about that.

    MBR infection is the first thing to check in this case.
