Have the alerts now ceased

Nope, still going. Not quite as often as before, but plenty often.

hy agian jpek please run and attach a fresh scan o frst and can you provide a picthure of what avast say it will give essexboy some information where to loctat the infection, is the popup still related to the wpap infection or does it say something else?

Which scan do you want me to do? The FRST?

Here is a picture of one recent popup (attached). It’s all about the wpad.dat, but sometimes it gives an IP address after the http and sometimes it doesn’t mention Outlook. Mostly, they’ve looked like this lately though.

Hmm when I reset the registry dat that should have gone, but it is now appearing to be from office which would tend to point the finger at an e-mail

Lets check the registry again

Enter the following data in the FRST search box and press search registry

wpad.browsersecurity.info;wpad.dat

Do you use office to collect e-mails ? And does this occur when office is not running

I use Outlook for emails. I closed it and this is what the wpad.dat error started generating:

Hmm could you run the registry search again please as that is where that is generated from

What would you like me to enter as the registry search term?

Here’s the latest wpad.dat threat.

wpad.browsersecurity.info;wpad.dat

The delineator is a semicolon

Well, you asked me to do this just recently, and the results are the same. This time I closed Outlook when I ran it.

Aye I did but if you look back then the first time you ran it nothing showed, but there was a result on the second run

So, no further suggestions?

See Reply #34.

Here (attached) is the log from ComboFix. A couple of caveats. When it was running before the restart, it threw up a series of error messages, such as the ones I’m attaching about various files, saying first that it couldn’t back them up and then that it couldn’t backup and then couldn’t restore several files in the C:\Windows\System32 (or maybe they were all in C:\Windows\System32\config, I’m not sure.) There were a total of maybe 5 or 8 such files, with two error messages for each.

Also, when the system restarted and ComboFix came back up to finish its process, there was an instruction to not run any other programs while ComboFix was generating the log, but it was too late for that, as some program automatically come up on my system at startup, and I hadn’t known to turn them off. One of the programs that started at that point was the Avast virus protection you had indicated I should disable. I did disable it (disabled all shields) but only until the “next startup” so it came up automatically after the startup. Please, let me know if I need to rerun ComboFix because of this.

Meanwhile, threats are still being detected.

Hmm this is a bit baffling,… Could you run this fix and let me know the result…
