I did some research on Comodo ZoneAlarm, there is an uninstaller tool. https://forums.comod...0.html#post_id6
There are four drivers Comodo ZoneAlarm installs on Windows,.. VirtualBox: Support driver, Host-Only Network Adapter driver, Bridged Networking driver, and USB Monitor driver.
Simply uninstalling Comodo ZoneAlarm does not properly remove the VirtualBox drivers.
To properly uninstall, delete, or remove these files do the following :
Open My Computer and navigate to C:\Windows\System32\drivers\
Once in C:\Windows\System32\drivers\, find and remove these five files:
Take note that, since you already removed Comodo ZoneAlarm, you may not have all five of these files. Delete whichever ones that are there.
Close the C:\Windows\system32\drivers\ window.
Open Registry Editor (regedit). In regedit, navigate to HKEY_LOCAL_MECHINE\SYSTEM\CurrentControlSet\services\, look for five folders :
Right-click each of these folders and click Delete. Once again you may not find all five folders since you uninstalled Comodo ZoneAlarm. Delete whichever ones you find.
Close regedit, Restart your computer.
Edit: If after removing the VBOX files, drivers you still have issues,.. I would just do a clean install of Windows 7 and be done with it!
