    Hello,

    I dual boot two versions of win7. I would like to scan the other is while booted up into another one on a schedule.

    Antivirus progs allow me to for this manally But not on a schedule

    Any avs that do this?

    Thanks

    I don't see how since both operating systems would have to be running at the same time.

    When you do this manually, you are really just scanning the other drive, not the other OS.

    BTW, running scans manual (or even by schedule) is typically not that essential. If you have a real-time anti-malware solution running whenever your system is running, everything coming in and going out of your computer is being scanned in real-time. Supplemental scans are really just for peace of mind. I am not saying don't do them. I am just saying if you keep your OS and your real-time security software current, and you avoid being "click-happy" on every unsolicited download, attachment, link, and popup you see, manual scans should never find anything.

    I'm not sure why this would be a problem. If they are both Windows 7 they should be compatible file systems. Each one should see the other as a different drive letter. You should just be able to schedule the scan as you would for any alternate drive. It's not a great idea to alter files on an OS disk that isn't currently running but I'm pretty sure there is nothing stopping it.

    Why would this be a problem? It would be the same as initiating a scan from a flash drive - which happens all the time. And to that, not sure why a file would be altered anyway - unless the scanner tagged it as malicious.

    Just mount the other OS's disk. Shouldn't this work?

    With "mountvol" command, for example. MAybe it also works using Disk Management mmt

    False positive on a system file. I've seen it happen.

    False positives, while possible, are rare events that could happen at any time. In terms of the best security precautions, we should be running scans on OS disks that are not running! Why? Because if a system file has been corrupted or compromised, the can be "altered" and made safe. When you run scans on the OS from the boot drive, it is possible the infected system file is "open", locked and cannot be cleaned. Not good. This is one reason it is often recommended to run scan in Safe Mode - because more system files have not been locked open and can be cleaned.

    Also, if you have booted to a different drive other than your normal boot drive, there is a much greater chance any malware that might otherwise boot with the normal OS would not be running and therefore cannot interfere with the scans. So again, you get a better scan.

    False positives certainly are not good. But they are much better than a malicious file going undetected (false negative).

    Sorry for the confusion I was asking about booting into one version of win7 and scanning the other OS drive while it was not running.

    Microsft esentials doesnt do it on a schedule which is not surprising since its a bare bones program.
    Also web root doesnt do it.

    I could install an AV and find out but AV programs in the past have been difficult to remove which is why i would rather not install and find out.

    Ummm, you sure? I no longer run W7 (and recommend you upgrade to W10 ASAP) but I remember you sure could schedule scans with MSE. And with Microsoft Defender (formally Windows Defender and the W10 version of MSE) you can schedule scans with Task Scheduler too.

    But scheduled scan will not run if the computer is turned off. And if you are booted to the second OS, the first OS may be seen as "off" and not run as scheduled. But again that should not matter if all drives are being scanned.

    Also, MSE, by default does run regular scans. So not sure why you feel you need to schedule another.

    Yea, just mount the drive as X: or whatever. If you can see the drive in explorer, any AM will scan it if you select it in the scan options.

    You can run scheduled scans but you cannot select which drive its is only your current os.

    Use "mountvol", make a batch and start it at logon with the scheduler. You can even mount it temporarily at the same time you scheduled the AV scans if you don't want it mounted all the time. "Mountvol" can unmount

    Ummm, it will scan all our drives - including USB drives. It will also scan the running environment (what's happening in memory as part of its behavior analysis).

    Configuring custom scans (scheduled or on-demand) is not very intuitive, unfortunately. But then most users would have no need for custom scans. And since it scans our systems automatically when idle (not to mention everything in real-time), I don't see a need to schedule any additional scans.
