Hello folks,

 

We recently received a donated computer for veterans to use. It's a Sony all-in-one, runs well. We suspect that there is a virus on it. When ever we try to use IE or Chrome there are certificate warnings for most websites that prevent it from being viewed. For example we tried to download Malware-bytes and it prevents us from downloading it. 

 

We tired running Combofix, but after booting OS8 into safe mode, we get an error that the program does not support the OS. However, I believe that for some odd reason, it thinks we are running Windows 2000. Anyone have a work around or any suggestions? Thanks!

Check your time and date (should be in the lower right corner) make sure that this is correct. When the time is not correct it will cause certificate warnings.

 

You can change the time and date by clicking the time > then change time and date settings at the bottom.

 

If the time is incorrect this means the computer has a bad cmos battery, whenever the machine is unplugged the time will reset. If it is left plugged in and power does not go out the time will remain correct after setting it.

Thanks for the reply! Checked it, it has the right day and time.

You can try resetting Internet Explorer: in the top right corner click the settings icon or in the menu click tools > then internet options > click the advanced tab (the very right tab) in here there are 2 buttons 1 restore advanced settings, click this first then click the reset button just below, when you click the reset button put a check in the box delete personal settings, then click reset again. Now close internet explorer and re-open it.

 

If you still have issues I would suspect you have a possible virus. I will let some one from the malware response team help you with those issues.

You are welcome, if you intend to use google chrome, you will need to delete the google chrome profile and then uninstall and reinstall.

 

Edit: I still recommend downloading and running a full scan with malwarebytes before doing anything personal on any used computer that was not wiped.
