Apparent CIS / Avast 5 incompatibility

I have CIS4(FW & D+) and Avast! 5 (latest updates on both) both 64-bit versions on WinXP 64-bit and they work OK together, but not the same for WinXP 32-bit, in fact it gives increasing video artifacts that get worse over time and finally give insuficient resources error and a system wide crash.

As you might know I’m a PC tech and I have installed the 32-bit of both on 3 PCs with the same results, I had them updated from CIS 3.8 & Avast! 4.8, and alsmot the same software is being used in these PCs, I’ve updated only CCleaner and other utilities to the latest versions. The only thing that might be resident in memory affecting WinXP, and I don’t think is probable, is PerfectDisk 11 build 170 (latest), has 2 services that try make the background defrag while the system is idle. I have uninstalled CIS4 and the 3 systems seem stable now, I’ll let them like that for a day or 2, but I’ll leave another PC with the Full CIS suite and see what happens.

I always install Avast! first so CIS can recognize it and don’t ask me about the Avast! installer if I do it otherwise.

Meanwhile please COMODO support, contact Avast! support or even better why not COMODO dev team contact Avast! dev team and try to see if anyone reports similar conflicts and perhapos maybe Raxco (makers of PerfectDisk) too.

I’ll report in a couple, cya.

Report1: I know hasn’t been 2 days but I have found out something: Confirmed any of them can work alone fine, 3 I stalled 3 PCs with Avast! 5 and 3 with CIS 4 (complete: FW, D+ & AV). Something similar happened when CIS 3.5 went out. On all PCs aI had CIS 3.8 and Avast! 4.8.

PS: I’m posting this in COMODO and Avast forums.

Are you using Avast! free or another version? Does Comodo allow you to exclude Avast! folder from monitoring? I do that with OA and Avast! and that avoids potential problems.

Yes, it does, but this is not about a specific path or drive, is a WinXP wide malfunctioning and crush.

So you have it excluded and it makes no difference? Which Avast! version do you have-5.0.545 free?

I didn’t notice any problem using avast 5 and cis 4 on my xp 32 bit pc. :slight_smile: . i just excluded avast temp files (c:\windows\temp\avast5*)and avast folder from cis scanner .

there was no issue running both software here without excluding anything ???
