Windows-7 did not find my antivirus Avast on the PC software

I recently started getting the message of Action-Center "Windows 7 didn't find an AV on this system.
I use Avast (free) for years - since Win2000...

I use Win7 (build 7100) for almost a year, but it is only recently that my Win - 7 has started giving me this message.  Yes, yes - I know-time to upgrade. I have only a few months with 7100...   :-(

An Avast forum suggested I delete the system32 folder/wbem/repository after the closure of some services.
Unfortunately this must have been for XP, because there seems to be much too many services taking into this folder. I can't keep closing all!

So, how can I get rid of that message, apart from upgrading to Avast Professional (which cannot always help)?
Another easy answer is simply disable messages on protection against the virus, at least in my case. But what happens if a newbie has this problem?

Sorry if this message seems redundant, but the other forum responses seem to be for XP or Vista,

Thanx.

Free avast works fine on Windows 7 but it can't on non - RTM builds more (I don't know this). I used it without a problem during the beta until the RTM version. Try to uninstall/reinstall Avast. If this does not resolve the problem, maybe you just install a different free antivirus until you make your own to the RTM installation. Also, you sound like a user, but for completeness, I should also mention that malware infection can cause this problem so make sure that the computer is clean:

Regarding the process of change of name of the repository, it works on XP and Vista, but I've never tried it on Win7. Since Win7 is no longer the Security Center, he can no longer work. I do not know. However, here's the correct process if you want to try again:

Start > Search > type: cmd
When cmd appears in the above results, right-click and choose "Run as Administrator". At the elevated command prompt that will appear:

net stop winmgmt [Enter] [answer Yes to the guests]
CD C:\windows\system32\wbem [Enter]
repository.old repository ren [Enter]
net start winmgmt [Enter]

Exit command prompt and restart the computer.

I have a vague memory of this operation on a Vista machine and who need to do this in Safe Mode prompt orders, but I'm afraid, it was summer and I can't remember. I understand that you use Win7 but maybe the same action there were under Vista so I include the information for you.

  • Windows Update did not find updates more. The progress of the download stays on 0%...

    I guess that it is a result of http://support.microsoft.com/?kbid=947821.

    Windows 7 can not find my file?

    The folder is synchronized with Google drive

    I could add 'system' of permissions, but this causes permission errorsI is currently seeking 17000 files manually and it's a pain

    Any way to get Windows 7 to find 'xp style' folders on the fly without all these stories of cataloguing which causes has other "cannot find' bugs even when

    Actually found a solution so for all those who use the Googledrive folder on Windows - you can cut search indexing (uses of data which is not updated on the records of Gdrive) causing Win 7 search "on-the-fly" = a little more slow but even faster that I can read names of 17000 files

    Just open your main Gdrive/Windows folder and choose search & Union Options / folders:

  • Windows did not find antivirus software on this computer

    It is to be expected.  Windows Defender is an anti-malware program that is designed to protect you against spy-ware, and ad-ware only.  However, there is no capacity for the anti-viral.  You should always install an antivirus application any.

    Since neither updates Jan - 10 have installed, I'm going to hand you Support MS in the hope that they can resolve the problem. See below.

    That being said, is an interpretation of the 80070017 - cyclic redundancy check error "a device attached to the system does not work," which suggests that a hardware problem might be the cause of the error (although I must say that it is a very low possibility in this case).

    Good luck!

  • Windows CD can not find installed hard drives

    I have a PC that has windows XP installed and worked well and I have DSL so I kept it updated. It has been updated for the updates. It was a month that it seemed hung on a windows update and I've finally powered down to exit the update mode. After that, he would finally in XP but would not other that the busy when an icon is clicked. I decided to reload XP using the same CD I used originally when I built PC. It will load the drivers to install XP, but when installing windows is selected it says no hard drives found. When booting 2 HARD disks are displayed, but are not detected when you look in the BIOS. I've tried changes in the BIOS as auto detect HDD including default BIOS and not go. I remembered to change a partition using Partition magic 8.0 and decided that might be the problem, so I started in the magic of partition and formatted part C of the HDD in NTFS, but the results are the same. Any suggestion is appreciated. TIA

    Do you mean you see a message like this?

    Setup did not find any hard drives installed in your computer. Make sure that the hard drives are powered on and properly connected to your computer, and that any hardware configuration of the drives is correct. This may involve a diagnosis provided by the manufacturer or the installer running. Setup cannot continue. To quit Setup, press F3.

    If the disks are not appearing in BIOS, it seems unlikely that XP will be able to see them no more.

    Describe the best you can, your hard disk configuration...  IDE, SATA, SCSI, RAID configurations...

    You build the hardware yourself or is it a system store bought?

    Are you able to determine when the system turns on, the brand and model of your motherboard and the BIOS it is running?

    Without more information, I can only offers these general reflections where to search:

    When you see a message like this, obviously the XP installation starts to load, but then when the installation program needs to go out and find your hard drive is not find the hard drive.  It means not necessarily your hard drive is defective and if it worked before, it's probably still plugged.  It simply means that the installation of XP is not able to find it.

    Looks like you need enter the BIOS on your system by pressing the 'Delete', F2, F10 or F12 key (what the key is good for your system), find the section where the types of hard disks and hard disk interfaces are configured and temporarily change the setting so the XP installation is able to find the hard drive.

    Where to find the accommodation and how to change depends on your system manufacturer and the version of the BIOS, so you end up having to look at her.  If you know your system brand and model, we can probably help you find a job.

    You must locate and change the interface mode to your hard drive in the BIOS so that when installing XP loading, it will be able to locate the hard drive.

    Before making adjustments, you should take note of what are the current BIOS settings, so you can change when you are finished.

    The adjustment varies so here are some examples that I have accumulated:

    The adjustment is done in the BIOS and could be in Integrated Peripherals, Configuration of SATA, SATA Mode device.  After you make the changes, save them and restart your XP installation program.

    If you find that the mode is set on the RAID/SATA mode, change the IDE mode.

    If you find that the mode is set to AHCI, change the ATA mode.

    If you find that the mode is set to AHCI emulation Mode, change the IDE emulation mode.

    If you find that the mode is set to SATA, SATA mode off or change the ATA mode.

    If you find that the mode is set to SATA Native Mode, disable the native SATA Mode.

    If you find that the mode is set on AHCI/RAID Autodetect, change the combination mode.

    If find you the setting that works for you, I would like to know what it is so I can add it to my notes.

    Do, or do not. There is no test.

    Correct, you will need to download the appropriate TXTmode drivers and put them on a floppy disk. If you have a MSI motherboard in your system, you will get these drivers from MSI.

    It would be also possible to get Windows to load with a change in your BIOS settings, but I recommend that get you the correct drivers.
