On Laptop B, I have removed the AIS and turned on the Widows Firewall and on Laptop C, I have still left the AIS. Both these machines were bought about 18 months ago and had Avast! Free and Windows Firewall on them. No other AV or Firewall installed on them until last month, when I installed AIS on them.
When you installed AIS on all 3 machines, did all 3 machines also have Avast Free on them prior to this and you
upgraded from Free to AIS or did you do a
clean install?
Did this problem happen after upgrading or installing AIS?
Laptop B's MBAM is clean (for now), but because you are on a network, all machines should be checked.
Have you tried an Avast Repair (only the machines that have Avast on them):
- Go to Control Panel > Add/Remove programs > Avast Antivirus.
- Scroll down and choose Repair function in the pop-up window.
- Reboot.
Depending on if you upgraded or did a clean install and if the Repair works/fails, you may need to do a clean install of AIS:
1. Save a copy of newest version of Avast (5.0.677) and save it to your HDD:
AIS –
http://files.avast.com/iavs5x/setup_ais.exe2. Download the Avast Uninstall Utility, aswClear5.exe
http://www.avast.com/uninstall-utility and save it to your HDD.
3. Disconnect from the Internet at this time.
4. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
5. If Step 4 fails, boot into
Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool.
Uninstall ALL previous products of Avast on your machine at this time (Avast 5.0, AIS, etc.).
6.
Reboot.
7. Install the newest version of Avast and
reboot.
8. Get Internet access and register your license key for AIS.
9. Update the Avast definitions.
If problems, check to make sure AIS firewall allows avastSvc.exe internet access.
- If it does, delete the entry for it and reconnect to the Internet. This should force the firewall to ask permission again.
If you continue to have problems, this does not look like an Avast issue, but something more we will have to explore. Let us know how this goes. Thank you.
