My system WinXPHomeSP3. I have been using CIS for a long time and am reasonably familiar with it and it had been working fine and updating OK. (Usual problem - if it isn’t broken don’t fix it!).
I downloaded and saved the latest free CIS file cisfree_installer_x86.exe, uninstalled my previous version CIS ver 3.9.81003 from Start>All programs, switched off modem to come off-line, rebooted, and installed the latest CIS, and got back on-line - all working OK, except that the CIS Sandbox etc confused me with various alerts.
So I switched off modem and uninstalled above latest CIS then for curiosity checked with Control Panel>Add/Remove and was surprised that CIS was still listed - so uninstalled from there. Rebooted and reinstalled CIS today from previously saved (15 May 2009) CIS installer file CIS_setup_3.9.76924.507_xp_vista_x32.exe and switched modem back on-line Reinstalled OK and can get on-line with Firefox and IE8 OK, note CIS version is showing from Miscellaneous>About as 3.9.81003.508.
Opened Comodo and tried to update AV definitions but error message states “Failed - error 113 update could not be completed seems internet connection lost halfway during update download please check your internet connection”. I have tried to update several times over a few hours thinking that your update server may be down, but still get no update!
Please advise what to do to get the AV updates - noting that I prefer to retain my previous CIS version (not the above latest installer file - which I still have saved).
Early response appreciated as my AV defs are almost 1yr old!! >:(
