Ping a website works but cannot browse the internet with any internet browser and cannot use mail apps like Outlook to send or receive
We are working with a specific problem with windows 8 where we had to delete firewall, antivirus, antimalware, etc. After restarting the computer, for some reason, we have no browsing access. In additional, Outlook doesn't work, yet we can ping website. Note however, we are using the same computer VPM to use the internet (that is, we can browse the internet within the VPC of the same computer with the problem).
How can get browsing capability again? (one last thing, we had internet Explorer, Chrome, Nightly (FireFox) and Safari; we uninstall all except Internet Explorer)

Check proxy setting in internet explorer.
go to internet options --> Connections --> LAN settings
If you ping www.yahoo.com and you get reply then your internet is fine.
Need to check proxy settings only in applications.

Also check that the DNS Client service is actually running on the computer - the DNS Client turns web address "names" into their corresponding IP addresses. If the client is running the computer doesn't know how to resolve these names - which is one reason why you can ping an IP address but not a name.
After the above, try:
1. System File Checker. Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete and restart the computer. Test.
2. Run DISM.
Open cmd.exe with Run as Administrator.
DISM.exe /Online /Cleanup-Image /Scanhealth (takes 15 - 20 minutes).
DISM.exe /Online /Cleanup-Image /Restorehealth (takes 15 - 20 minutes).
Restart the computer and test.

Will try DISM as last resort...
Internet options seems ok (see pic below)

I am not sure about it. But I can tell you mostly all firewall vendors make this programs in such way if a user removed all pre-configured rules OR rule section is empty(no rules are there) then firewall must block all traffic. It's mean if any firewall uninstalled partially but core files are remained and running on systems which could not able to find rules from rule section then network does not work.

"if a user removed all pre-configured rules OR rule section is empty (no rules are there) then firewall must block all traffic." ...this sound super logical. Ok this being the case and if this would happen again, instead of going thru all these tedious-time-taking tasks, how can we "unblock" all the traffic or place "pre-configured rules" as it was prior any firewall apps installed?
ASKER
We resolved the the problem by running a script and cleaning up the firewall Comodo that caused the problem.
The entry on ID: 40719420 referring to "pre-configured rules or Blocked Traffic" seemed a viable cause of the problem; if we wouldn't have had the solution the solved this problem, we would have directed to ID: 40719420 cause in order to solve it. That being said, we would like to know how to "unblock all the traffic" or workaround the "pre-configured rules" in order to solve it.
Please advice.

Run TCP/IP Reset and DNS Flush.
Open cmd.exe with Run as Administrator
Then netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer
Of course, you may not have eliminated all the malware.
