If you updated to CIS rather than uninstall and reinstall it will not install all the components of CAVS. Try a clean uninstall and re-install saving your configuration if you wish and importing it into V3.5. Try that and let us know if that brings back the context menu item.
Thank you for a quick reply. I believe I did a clean install since that what was suggested in one of the posts. I will try a clean reinstall one more time since it was possible for something to go wrong during installation.
Thank you again. I will report back in a few minutes.
[EDIT] Unfortunately didn’t work. I did the following:
Defraged the hard drive.
[EDIT 2] Just updated another laptop which also runs XP Pro SP2 without any problems. The right click scan is present in the menu. Also there is no problem on my desktop which runs XP Pro SP3.
As it is only on this computer and all your other computers are working fine could please post a bug report Here please with full details of your computer OS (XP, Vista, SP?, x32, x64) and also any other security programs that you are runing.
EDIT And also a copy of your last post showing the tasks you have done.
I figured out what was wrong. Last night I was trying also to install service pack 3 and I was getting an “access denied” error on the same laptop. Whatever I would do the SP3 would refuse to install. After doing a search I found out on Microsoft’s site that some registry keys can become restricted by certain programs that change the system access control lists (SACL) in the Registry so that administrator accounts cannot alter them. I thought that could be the reason preventing also the CIS from modifying registry properly and thus resulting in missing “scan with Comodo Antivirus” from the right click menu. I was right.
The workaround was to reset the registry and file permissions which is described in http://support.microsoft.com/kb/949377 in Advanced Troubleshooting section. After doing so I uninstalled the CIS and then reinstalled it. The “scan with Comodo Antivirus” was back.
I hope that this will help anyone that has or will have a similar problem.
Thank you for posting back with the way to solve the problem.
I’ll close this topic now. If you should encounter further problems, PM an online moderator with a link to this topic so that he can open it.
