OS: XP x64 FW: CIS 3.14 (Firewall/Defense+ only) AV: Avast5 This is an unusual issue and hopefully posted in the right place. Over time, I have noticed my registry growing at a rate I consider to be alarming, particularly since I neither game nor install much in the way of new software. To investigate potential culprits, I started poking around using jv16 Power Tools 2010 Registry Finder. With Comodo as the sole search parameter, I found nearly 135,000 entries. The size of the .txt file generated is 19MB. Attached is a screenshot from jv16 PT. So far, I haven't received any useful feedback on the Comodo forums. It seems to me that anytime anything is either updated, upgraded or changed in any way, Comodo writes to the registry without ever cleaning up after itself. I'm wondering if anyone here has seen the same behavior. I'd like to ditch CIS, but not many firewalls are compatible with XP x64. Any recommendations here based on direct experience would be greatly appreciated.
