I installed the Cleaner (grabbed from the site today) and ran the disk cleaner. I Also made some changes in the Windows settings.
I rebooted and was told that I could finalise or restore. I chose to keep working to see if there were any problems.
Were there ever?
When I tried to copy an image off the Net, I was told that data could not be obtained from the Clipboard. Then all the pictures in FireFox went black. Then the computer rebooted and said it had recovered from a serious error. Then virtually nothing worked. I tried to Turn Off Computer and was told I did not have permission! So I rebooted using the kill switch, and was then able to use the computer. I tried to restore files, and 5 failed. There was no apparent report about which ones.
Please do mention the following to help the developers find out the cause.
Your Operating System (and whether it’s 32bit/64bit);
Security Software Installed;
How you produced the problem;
How you tried to resolve the problem;
Screen-shots with the error (if any);
Post Memory Dumps on crash if you encounter any;
All log files of CSC, if you had logs enabled;
Any other Additional Information;
Did you click finalize before continuing with the work?
Were you able to log on to your desktop properly (means whether only programs did not repond or whether it was a BSOD or continuous booting).
If you were able to log on, did you try to restore the back up from CSC->CDC->Backup to check whether it gets you to normal?
Did you format your computer now? If not, if you can upload the log file (found under C:\prog.files\comodo\CSC) it may help the developers to find out the cause.
