The problem is, on bootup avast starts as it should then it goes offline until comodo starts which takes several minutes, the problem started when avast started inundating my pc with popups which are spoiling a good program, and I get the feeling that avast goes offline until all the popups are loaded, which is slowing down comodo’s boot-up?
I have used avast for over 10 years and I would like to continue using it but it’s getting harder, any ideas welcome
- Which Avast…? (Free/Pro/IS/Premier)
- Which version…?
- OS…? (32/64 Bit…? - which SP/Build…?)
- Other security related software installed…?
- Which AV(s) did you use before Avast…?
Simple solution is to get rid of Comodo. (It’s a personal solution.) 
Solution is simple: Keep only one security solution and get rid of the other: https://forum.avast.com/index.php?topic=211973.0
Do what bob3160 recommends.
Comodo doesn’t like Avast anyway. Going without protection for 10 minutes is too long.
Hi again, sorry for the late response, I was waiting for the usual email alert which did not come so thanks for the suggestions, I have used Comodo as long as I have Avast probably more than 10 yrs with no problems as it is also a very good program.
My system is Win 7 Pro 64 bit and the AV I was probably using before Avast would be either AVG or Avira (free) and the version I have always used is Avast free and it has always been very good, I just cannot figure out why it won’t work with Comodo after all this time, regards Robert
Security software code changes constantly deep within the OS.
I have found in my experience, due to software updates (code changes) not to mention OS Updates that it is not unusual that programs will co-exist and then not, ‘especially’ with Security software.
I used too, years back run both Avast and Comodo however not now. As a matter of fact, these days, even if I totally remove Avast, Comodo does not want to even install. Just saying
Hi again, does this site send email alerts when a question is answered? and thanks for all the info, you think it could be an update scrambling things, although I am fed up of Avast telling me my pc needs cleaning is there a way to turn off the warnings? if I can do that swapping comodo might be an option, but is there another firewall as good or as easy to run, as I said earlier they have worked together very well, and still do, and I have not had a nasty in 10 yrs, it’s just the very slow startup which bugs me, regards Robert
- Yes, you can adjust it in the forum settings.
- Since W7 the Windows FW is quite good, use it.
Thanks, I’ve hopefully turned on notifications, but sorry I don’t have your confidence in WF, as I premised earlier after 10+ years of reliability of both Avast and Comodo the problems have only started with the increase of popup rubbish and I think it may be possible that it’s the popups which are slowing down the Avast boot up so if anyone knows if there is a way of stopping the popup rubbish from immediately loading it might return Avast to the good program it once was, if not Avast may continue it’s slow boot-up even with a different firewall, regards Robert
Provide some screenshots.
Sorry Asyn, I cannot find the usual attach paper-clip to click on, in order to attach a screen shot, regards Robert
See attached images
Hi, thanks for the guidance, I have reduced the pic’s by 30% for transfer, the first pic shows Avast going offline which lasts for about a minute & 20 secs + then Comodo will start or a warning of some sort will show, regards Robert
As has been mentioned, in the past Comodo has conflicted with Avast, the comodo firewall in isolation used to be OK, but by all accounts it is more than just a firewall. I have never used Comodo products so I can’t speak from personal experience only what I have seen in the forums in the past.
The second image (the bottom portion) is basically an Ad for an avast paid product, CleanUp and the Resolve button would ultimately lead you to the purchase of the paid version of CleanUp. I do not like this form of advertising at all bordering on scaremongering.
It might be a good idea to do a Clean Install of Avast:

If you need additional help with the Clean Install, watch this:

After removal and before the install, please watch how do do a customized installation
and avoid installing those items that you may not want installed.

Update/ Hi all, thanks for your help and ideas, I have not been able to try anything of late as my telephone and internet connection has been down for the last 15 days and 12 hours, OpenReach have been constantly working on it and it came back just an hour ago, and as expected all my emails and updates came flooding in, so sorry for the late response.
I will try the links which Bob kindly sent as soon as I am straight again and I will report back later as long as the internet connection keeps on working, regards Robert
You’re welcome.
BT can be a real pain, playing ping pong between OpenReach and BT. I lost my land line and Internet for 10 days some time ago, several engineer visits and still no resolution. They had added another line and switched several people over to that and we all lost connections as the new line hadn’t actually been commissioned (made live).
I had to use my Mobile phone as a WiFi hotspot.
Hi again, I have completed a clean install as suggested using the full tutorial provided by Bob, although unfortunately it has not sorted out the problem and as Avast free starts there is a yellow question mark showing for a few minutes before Comodo starts up. then usually an annoying popup asking if I want various other apps included in the Avast program, which I think might be loading up while the program hangs on start up.
For information there is a program called Revo uninstaller which also searches for and cleans out the leftover reg strings after it has uninstalled a program, it’s probably a lot easier than downloading avastclear.exe as it does the same job, regards Robert
It sounds more like you need to set Comodo to allow the various Avast connections
Uninstalling avast and running Revo will be no different to having used the avast uninstall utility during a clean reinstall. All of the various avast connection requirement will be the same, you need to get Comodo firewall to allow them.
Comodo should be up and running (system driver) much sooner than you think, if you are thinking that seeing the icon in the system tray is it starting, that allows access to its interface.
Hi David, I thought that I had all the Avast connections allowed, but I have just had another look at the Comodo dashboard and by clicking around ( on very small text) I have found a firewall setting that I have not seen before, and there was provision to indicate in three places that Avast was a safe program so I have marked it as safe and hope that: that does the trick, I’ll update later regards Robert
