Am I all cleared now?

I have Windows 7 installed with latest updates and periodically scanned with latest "Malwarebytes" and "Avast free Anti-malwares" on-line all OK and normal. This morning after installation of a free application called Readon TV Player, Version 7.6, downloaded from www.downloads.com (please noted that I ALWAYS scanned any downloads for virus-free with Avast/Malwarebytes prior to installations) and clicked the player, I then prompted with both a voice-prompt and a screen-prompt telling me that my PC has been compromised that my PC's security is at stake! In addition the screen-prompt locked me out from other mouse-activities and constantly prompting me that I should contact their: Certified Live Technician on a toll-free number instead. I did that but the other end said that he wanted to remotely assess my PC to find out the conditions at my end. I immeditely suspected it might be a "trick" and hanged up.
I resetted my PC and rebooted Windows. Then I sequently scanned with a) Windows Defender which found OK, b) full Malwarebytes scan which also found OK and lastly c) Avast for both virues, network security and even my Firefox add-ons which also found OK too!
So judging from this, am I experienced a "SCAM" via the new applicatiopn (Readon TV player) through my internet connections, or have I still accidentially got my PC infected with some security virus but not being able to "remove" by Windows Defender, Malwarebytes, and even Avast Scans?? Is their any other things I should do BEFORE I can finally declare it is ALL cleared on my existing PC??
Thank you for any suggestion!!

P.S: I have already unistalled that Readon TV player from my PC.

Remember being told some years ago to do the various scans in safe mode, can't recall why.

Thank you for your info regarding CNT's Download.com malpractice back to date to 2012! Indeed I always trust CNT's sites, may be until now! Also the scans which I had conducted were all done in NORMAL Windows, not in SAFE-Mode as well. I have been made aware that Windows' Safe-mode would NOT run the 3rd Party Drivers/App like their Normal-Mode does. As a possible consequence of running in Safe-Mode, it should be far less "interference" from some dodgy drivers/Applications as well. I may consider running my Malwarebytes and Avast Scans again in Safe-Mode instead.
Thank you for suggesting it!!

Unfortunately, the one thing that you can NOT be sure of on any PC, MAC etc, is that it is "All-Clear".

All forms of anti-virus, malware software are in catch-up mode, just like Flu Vaccines etc.

Interesting. It found a trojan on my PC that Microsoft Security Essentials and Malwarebytes both missed.

You stated that you used avast free and Malwarebytes, now you tell us that you have Microsoft Security Essentials running.

You cannot run both MSE and Avast! there will be conflicts.

MSE is at best baseline security and Microsoft tell users to use a 3rd party Antivirus.

I'm not running Avast. I have been running MSE with an occasional scan using Malwarebytes. I have noticed unusual disk activity on my PC for some time now, and neither MSE or MBAM showed anything untoward whereas SAS has picked up a variant of Trojan.Agent. It looks like I need something better. The question as always is "which anti-virus packages are the best?"

Edit: I'm not the OP.

There isn�t a single anti-virus or anti-malware product that will find all viruses or malware in existence today! Whenever I think I have some malware infection (never had a virus infection!) I have scanned with various different products, and some will find malware that others have missed. The products that I have run are HitmanPro, Malwarebytes Anti-malware, Malwarebytes ant-rootkit, JRT, ADWCleaner, 9-lab Removal Tool Online Scanner and ESET Online Scanner, all one after the other, but still never sure the system is totally clean! And never download from poor reputation sites, such as CNET, Softonic, Brothersoft, there are other providers of free software which contain open candy or unwanted software.

My experience above is looking more like a "SCAM" rather than an actual Virus infections, i.e.both the Voice- and Screen-prompts that I experienced were looking more like a FAKE from that program I downloaded. The Tool-Free number that the screen-prompt suggested I shouild contact is Very dodgy indeed as they had no mention of WHO they are when I called them!
I have "fully" re-scanned my PC both in Safe-mode and Normal-mode using fully updated Malwarebytes and Avast with OK Indications. I also scanned for Rootkit using Malwarebytes Rootkit Scan, and even Norton on-line scan with OK indications as well.
I know that most of the Anti-virus/rootkit programs are playing catch-up mode and as a result there is always a MIS!

Good to here SAS did it for you


Some sites to have a look at when you've the time:-

The latest news update tests appear here, best to think of test results as a guide and of course when asked everyone has their favourite ..... hopefully based on personal use and experience:-

As they say on TV, other web sites are available to look at too
