Win 7 Pro only view HTTPS sites

[Tokyo Jim]

Here is the situation, I have 2 machines running Windows 7 Pro. I've run Avast on them for quite sometime now and everything worked fine until the morning of Jan 28th 2011. I could not go to any websites that were not secure sites. HTTPS/yes HTTP/no. I tried everything in the book and the only thing that fixed my problem was disableing Avast. Is this a known issue? I didn't see anything in these forums about it. Anyone else having this problem? It must have been an update.

What version of avast free/pro/ais and what build version (5.1.889, etc.) ?

What is everything in the book, so we don't repeat what you tried ?

Have you recently updated the program ?

What is your firewall ?
Don't disable avast, as that leaves you completely unprotected, start by disabling the web shield and see if that works.

Free/5.1.889, The Book = resetting winsoc/tcp, turning off windows firewall, restore points, tried using firefox.

Well, the Windows firewall doesn't have outbound protection enabled by default, so unless you enabled it, that shouldn't be the problem.

Whilst resetting the winsock/tcp is a good idea I'm not sure that would have been the problem if it were I wouldn't have expected you to be able to connect to https sites either if it were corrupt/broken.

Are you using any sort of proxy to connect to the Internet ?

Having used system restore that may also have brought unexpected results, I have never had much confidence in it.

So if none of the above apply it may be best to do a reinstall of avast and possibly a clean reinstall having used system restore.
- Download the latest version of avast, 5.1.889 http://files.avast.com/iavs5x/setup_av_free_eng.exe (English only) and save it to your HDD, somewhere you can find it again (if you didn't save your last download). Use that when you reinstall.

- Download the avast! Uninstall Utility, aswClear5.exe find it here and save it to your HDD (it has uninstall tools for both 4.8 and 5.x).

• 1. Now uninstall avast! (using add remove programs, if you can't do that start from the next step), reboot.
• 2. run the avast! Uninstall Utility from safe mode, first for 4.8 if previously installed and then for 5.x, once complete reboot into normal mode.
• 3. install the latest version, reboot.

That's me for the night 3:45am here.
