CIS Installation
- Please
read the installation instructions carefully and review system
requirements before installing Comodo Internet Security.
- The
CIS software itself is identical for all customers regardless of the
package type. All versions include all security features,
technologies and updates. The difference between the package
types is additional services such as TrustConnect, Cloud Backup and
the Comodo Guarantee. Activation of additional services is carried
out after the base installation is complete.
- Please
ensure you have first uninstalled any other antivirus and firewall
products, including Comodo AV/FW/CCS. Failure to remove other AV and
FW products could lead to conflicts which cause CIS to function
incorrectly. We advise users consult their vendor documentation for
help to remove specific programs. However, the following steps
should help most Windows users:
- Click
the 'Start' button to open the 'Windows Start' menu
- Select
Control Panel > Programs and Features (Win 10, Win 8, Win7)
- Select
your current antivirus or firewall program from the list
- Click
'Remove'/'Uninstall' button
- Repeat
process until all required programs have been removed

Note about Windows XP
/ Vista
- CIS
v.12.0.0.6882 and above does not support Windows XP or Vista,
period.
- The
auto-containment and virtual desktop features simply do
not work on XP / Vista, so you cannot take advantage of one of our
core protection features.
- Comodo
strongly recommends anybody still using XP or Vista to
upgrade immediately. Microsoft ceased
support for XP/Vista years ago and the number of serious
vulnerabilities in these operating systems is almost innumerable. By
using them you are
exposing yourself to substantial risks which signature-based
antivirus cannot protect you against.
Windows 7
- Microsoft
ended general support for Windows 7 in January 2020. Devices running
Windows 7 will only receive security updates if the user has
purchased a 3 year extended security updates (ESU) package from
Microsoft.
- Because
of this, Windows 7 is no longer an officially supported operating
system. Unpatched vulnerabilities introduced by the underlying OS
can compromise the protection provided by CIS. For example, a
weakness in a Microsoft API that CIS relies on can undermine the
protection of CIS.
- All
CIS critical security features will continue to work on Windows 7,
including auto-containment, antivirus, and firewall.
- We
will also continue to fix critical and blocker issues for CIS on
Windows 7.
- However,
future CIS releases may contain features that are not included/do
not work on Windows 7.
- We
understand that many customers still use Windows 7, and hope that
this information helps you make an informed decision about
transitioning those machines to Windows 10 / 8.1 / 8.
