OK, thanks for answering my question. Enjoy your holiday!
I don't think your problem is caused by malware but if the problem is indeed malware related, within 2 weeks, a lot of malware can morph and change over time. I do not advise leaving this topic "open" for 2 weeks...
My advice would be to close this topic... disconnect this computer from any network, reset and flush the DNS cache as we did before, with the computer still disconnected from any network.
Reboot and see if the browser problems return. If they do then you know it is not the network or another computer on the network causing a problem.
If they do not return, then something in the network or another computer on the network, is causing problems.
You say things function normally in Safe Mode...
Use a product like WinPatrol (free for personal use) and note the various startup programs running.
Note the processes running... all in Safe Mode.
Then boot the computer normally and check the startup programs again... Eliminate them one by one rebooting after preventing them from starting at boot time, to see if this makes a difference.
If eliminating a program makes a difference, you have found the culprit.
If no difference after elimination of programs... look into the running processes... both from a Safe Mode stand point and a normal boot standpoint... make a note of the additional processes, when booted normally. Do not stop any processes but just note the additional ones... stopping a critical process, could cause additional problems.
You can start a new topic when you return, after performing these "tests", report your findings from the "tests" and also let the helper know what steps we took:
P2P Advisory - removed:
µTorrent
uTorrentBar Toolbar
OTL
Malwarebytes' Anti-Malware
Reset IP-Flush DNS-Renew IP
ComboFix
Reset Router
Reset Internet Explorer Settings
Reset IP-Flush DNS-Renew IP
MBRCheck - Scan
Please let me know you have seen and understand what I am suggesting you do. Once I have your response, I will close this topic and you can start a new one, when you have the time again, to devote to the problem.
