Windows 8

 

I use Mcafee, and unlike Malwarebytes or Ccleaner, it hasnever detected anything like babylon, tarma installer, delta search and similar.

 

Is it of any real use?

 

In addition I have the impression that it tries to lead to yahoo instead of goggle: I get pop-up messages to make yahoo my default search engine insted of goggle, and I suspect of Mcafee.

 

Any information on this?

 

Thanks

Well McAfee is anti-virus not Anti-Spyware and the items you mentioned fall into the category of unwanted programs or spyware. Malwarebytes is good for that, and I do not recommend CCleaner.

Although McAfee is as good as any other well known anti-virus program, it requires numerous services and running processes that consume a lot of system resources and often results in complaints of high CPU usage. Anti-virus software components insert themselves deep into the operating systems core and create files/folders/registry entries in various locations. If you do a Google Search you will find there have been numerous complaints about it affecting system performance. Those issues plus the cost factor are the primary reason many folks look for a free alternative as a replacement. McAfee is better utilized in an Enterprise system environment protecting many client computers.

Windows 8 integrates Windows Defender on Windows 8, a more robust version of Windows Defender (and uses that name) for its anti-virus and anti-malware protection. Although it uses the same name, it is not the same as Defender in previous operating systems. Windows 8 Defender provides the same level of protection against malware as Microsoft Security Essentials (MSE) and uses the same virus definition updates. You may want to consider removing your current anti-virus and activating it. For more information, please read Windows Defender on Windows 8 - Introduction and FAQss.


Please download AdwCleaner by Xplode and save to your Desktop.

Antiviruses have certain norms which decide whether it will detect a specific program as PUP or not. Maybe this white paper from McAfee can give some clue:

http://www.mcafee.com/us/resources/white-papers/wp-potentially-unwanted-programs-spyware-adware.pdf

 

And McAfee does detect PUPs if you have PUP scanning enabled.

PUPs may also be defined somewhat differently by various security vendors and may or may not be detected/removed based on that definition.

If you doubt that McAfee is functioning correctly, you can do the EICAR test.

 

Download the EICAR test file from here:

http://www.eicar.org/85-0-Download.html

 

McAfee should detect it when you save it. But don't worry, it is not malware, it is a testfile for AV products.

1) then how do I set Mcafee to delete PUPs?

 

2) I have identified the registry entries related to PUPs that I believe I have fully deleted. Can I delete them manually, at least all the values different to "default"?

again in microsoft forum they told me that I ran risks both deleting or not deleting them.

 

Here is a list

I don't use McAfee. If a McAfee user does not reply, you can always check with McAfee Technical Support or ask at McAfee Communities.

That information may also be in their User Guides.
McAfee System Protection User Guide
Mcafee Internet Security User Guide

In Post #3 I provided tools you can use. Both of them detect and remove the most commonly found Adware, Toolbars, PUPs, Homepage Hijackers, junkware and their related files, registry entries.

When I used McAfee back before I found MSE, I found that it automatically detected and took care of PUP's without setting an option, but that could have changed with recent versions of the software.

What version of McAfee are you using?
