I have been having no end of problems with Avast lately. For a start, I cannot search the web using Firefox without getting a messages saying this connection is untrusted. Not unless I turn off Avast first. I also have to turn Avast off to install many of my trusted programs. I even had to turn it off just to reach this forum, and a quick search of the site tells me I am not the only one who appears to suffer from the same problem.
What use is an antivirus program if you have to keep turning it off.
Sorry but out of pure desperation I uninstalled Avast. But even then Avast had not finished causing me problems, because after uninstalling it, it wanted me to reboot. The only trouble was that the computer would no longer reboot.
I tried restoring to earlier images created by Acronis True Image but none would reboot after uninstalling Avast. So, I eventually restored to my first image where no antivirus was installed. I installed AVG and can now say that I am not having any problems at all with either Firefox or installing programs.
I think this proves that there is definitely something wrong with Avast. Shame really because I have been using it for over 15 years before being forced to remove it.
There was no particular link, it was all https links. But even worse than that was having to turn Avast off to download and install most of my programs.
Not in all cases, but such problems could also denote the start of serious hardware problems.
I experienced this on a Vista laptop, where I first had to change a hard disk and secondly had the graphical card rebaked.
If it was an hardware problem then surely changing to AVG would not have solved the problem. Besides, all my hardware is brand new including the hard drives, motherboard and all its components.
As for my operating system, its XP Pro x64.
With Windows 7 or above I do not need to use Firefox, I just keep all my bookmarks listed on a wordpad and only have to click on the link. But that’s all I like about those operating systems. I always return to XP which in my opinion is one of the best operating system Microsoft have ever produced.
Before coming onto this forum a Google Search told me about the ssl scanning problem and as far as my Avast was concerned, surely it kept itself updated.
Just the same, when I have the time I am going to restore my systems image back to when I still had Avast and try out your suggestions.
Please do so and let us know wat version of avast was installed at that time.
There was indeed a problem with tls/ssl scanning under XP, but as I said that problem was solved.
A very strong indication that you where not using the latest avast version.
Note the the OP said that he is using XP 64bit (so must be Pro version) and that only goes to SP2, so that could well be the issue as the https functionality requires XP SP3 I believe.
That said XP Pro SP2 is based on Windows 2003 and not actually on the core XP OS, that too could be an issue.
