    Windows and browsers are rapidly minimizing and maximizing, no malware


    Windows and browsers are rapidly minimizing and maximizing - no malware accordting to Norton 360

    Video of the situation: Windows and browsers are rapidly minimizing and maximizing - no malware accordting to Norton 360 - YouTube

    The issue stared two days ago (20 June 2015)after I connected to my TV to see the game of thrones via VGA wire (this is usual practice for couple of years)

    I'm using Windows 7 Pro (service pack 1) in Dell Latitude laptop, checked that all my Windows Updates are up-to-date. Don't mind the two black blotches on screen.

    Checked if any keyboard buttons are hard pressed (stuck while pressed). Updated my Norton 360 and did full system scan - no issues found. Killed explorer in task manager and restarted the application. Escape button doesn't help.

    Recently, I got a notification that Windows 10 is available free to me - do you think Microsoft is trying to give a soft nudge via windows update.

    Any suggestions are welcome and highly appreciated.

    You said you already checked keys but is that perhaps F11 acting up? Strike it a couple of times.

    Also download and run KeyCastOW https://brookhong.github.io/2014/04/...n-windows.html
    It is portable so no installation needed. See if you can spot anything unusual.

    Hi,

    Please try Norton Power Eraser www.norton.com/npe and see if that helps.
    Let us know if you need more help! Thank you.

    Hi Praveen and Norton Support Team,

    Installed NPE, it found no risks - suggested old Java removal. Did that and installed new Java. Rescanned with NPE and Norton 360 with update - still issue persists.


    Hi GokAy,
    Tried your suggestions- no stuck keys 😭

    Would hate to format this laptop - any more suggestions?

    Please consider uninstalling Java. Only install it if you find something that needs it. Java is always a security risk.

    You system specs are not very detailed - so I don't know if Dell's newly released video drivers are applicable:

    If updating the video driver fails to fix the issue or if the driver is not applicable to your hardware, then consider these steps: Troubleshoot Application Conflicts by Performing a Clean Startup

    If those steps fail, then test the browser after booting the computer into the Safe Mode.

    You can also try a new (temporary) profile. You can enable the Guest account for that test. That will tell us if the issue is system wide or an issue with your profile/account.


    Does this issue happen for all browsers? If just one browser, consider uninstalling that browser, clearing out any left over folders and re-installing that browser.

    Ok, did you try this one?
    It may be possible some other program is causing it, so yeah I second clean startup as UsernameIssues linked.

    It could just be a faulty Keyboard or controller. Have u tried to boot in safe mode or to another OS, like a live linux CD/USB and see if the problem persist. If it does still it's a hardware problem if not it's a problem in windows like a driver/sysfile/DLL ect...

    Thank you all for your suggestions, I really do appreciate your inputs.��

    1. Booted in safe mode of existing windows profile - didn't see the issue till I connected to Internet via browsers (Firefox and Chrome). Rescanned via NPE - no risks. Scanned via Norton 360 - nothing found.

    2. Booted in safe mode of new windows profile - didn't see the issue till I connected to Internet via browsers (Firefox and Chrome). Rescanned via NPE - no risks. Scanned via Norton 360 - 2 browser cookies, resolved. Issue is back.

    --//--
    Q2. Would you suggest - any online keyboard diagnostics tools (without download)?

    Q3. I'll copy all my data in an external USB hard drive in safe mode with network - do you think I maybe copying the corrupt source (if it's an undetected malware)? Usually, I go to C drive > Users > copy the desktop, docs, pics & other folders

    Q1 Repeat. Any other suggestions - other than formatting?
