Problems with Malware: I am being well helped?

$

0
About a week ago a problem appeared on my computer (HP Pavilion g6, with Windows 7 and Win Defender originals, and Microsoft Security Essential anti-virus installed by me later)
I don't know how, a new program "anti-virus Security Pro" appeared (with no uninstall option); When I tried to remove it blocked everything; a friend pulled back on battery cover and unblocked; Then, I uninstalled MSE and installed Avast Free anti-virus and also CCleaner;
But such “anti-virus Security Pro” continued in my program list, and unfortunately my friend couldn't help you anymore;
That's why I asked for help in the Microsoft Community Forum;
Someone (which I will identify as "the ANALIST") responded and has been suggesting tips; However I started studying the subject and started getting scared that these tips could somehow be even more be unhelpful;
He has always responded very quickly, sometimes the tools he suggests I use, are downloaded directly from his post; I want to believe I'm actually being helped, but ...
Can you tell me, please, if these procedures are correct or if they have something weird? (I write from Portugal, so excuse my French)
Here is a diary of the suggestions that have been sending and I went running;

“Anti-virus Security Pro” is a rogue (a virus that disguises itself as a security program in order to infect the computer of the people). To resolve this problem do the following:

* start the PC in safe mode with networking (press F8 (or the F5 key on some computers) repeatedly when the computer is booting and choosing the option safe mode with networking. After this, just follow the tips in this tutorial below to remove "Antivirus Security Pro":

Block the processes of malwares and viruses using Rkill

In this tutorial is taught to use the Rkill to block the process of virus. After this is shown how to use Malwarebytes, Dr.Web CureIt, Kaspersky Virus Removal Tool, Norman Malware Cleaner, Nod32 Online and Super Antispyware to remove viruses and malware that are on your PC. Can use them peacefully, just disable temporarily your antivirus resident protection. And after the problems have been resolved you can uninstall all of these tools used in cleaning and return with your protection you already have. After this tell us, please, if the problem was solved. We are on hold.

ME:
I tried to start the win (Windows 7) in safe mode with networking, but appeared a Blackboard with "start programs" and “wait” at the bottom on the left... and it stayed that way for a very long time! I ended giving up and turned off (which was almost kill!) It is normal for the safe mode taking so long to start?

ANALIST:
Usually is quick to start this mode, must be the virus that is causing the delay. In this case, you can try downloading and running the Rkill in normal mode of Windows. And then you just go by following the tips of the tutorial that I passed earlier.

27 Nov ME:
I Installed the RKill and did a full scan with Avast free anti-virus, which found 10 threats of high severity (Win 32: Rootkit-gen (RTK); 6 files with Win 32: Dofoil-Ej (Trj); Win 32: Malware-gen; JS: Agent-CFl (Expl); Other: Malware-gen (Trj):

Then I did a full scan with Windows Defender, which found no threat;

Then run with Cclener who found some issues;

And also a full scan with Malwarebytes, which found a Hijack. security (cat. Registry value).

The “anti-virus Security pro” continues in the program column, although the computer was working normally, (apparently) although maybe a little slow.

About the problems that the Avast and Malwarebytes found, they are in their quarantines; the Cceaner cleaned;

Then, I tried downloading the Dr Web Curelt but before he could run and save the file he began doing a scan (with the screen spleen, like some sort of protection); found no threats;

Then I downloaded the Kaspery virus removal tool; I ordered a complete check, that it gave for 1 day; After a few hours he bloqued in 3% ; until then, it had found 8 threats, (Trojan program HEUR), that were to quarantine.
