This advert being is widely circulated on FB nowadays(See attachment).Its purportedly a remake of the Contra game by some unknown studio called Raize gaming.
I assumed it was what it claimed to be,moreover as it was being advertised on FB i thought it was legit.After downloading this so-called game from their link,i found that it didn't work and was demanding that i install some "simulator" to get it to work.
Frustrated i gave up trying,but shortly afterwards an executable of the game that was running in the background was flagged by AVG as a malware(bitcoin miner) and was blocked.
This set off some alarm bells,so i checked the FB post once again where i got it from,and surely discovered that many others had also reported the same issue-that it was being flagged as a malware.It was my mistake for not having checked the comments thoroughly before proceeding to download this fake game-actually i didn't think any app that was being advertised on FB would contain malware,as i assumed they would have verified it before allowing it to appear on their website.
I ran a full system scan with avg and it came up clean in the results.I even scanned my system with malwarebytes and hitman pro but they couldn't find any traces of that malware either.
However much to my surprise,i found that the executables were still running from multiple places within my primary drive (C : ) after i rebooted my system,and quite inexplicably AVG was not detecting them.So i manually found their source folders using task manager and deleted them all,only to find them still appearing again upon the next reboot.
So this time i downloaded Eset online scanner and ran another system-wide scan but it came up empty as well.I couldn't imagine that some of the oldest and the most reputable AV products like ESET ,AVg etc were failing to detect this generic bitcoin mining trojan.
As a last resort,i scanned my system using a tool called rogue killer,and it did manage to detect multiple traces of the app on my C: drive and deleted them all !! I hope i wont find it running again upon the next reboot!
I reported this ad to facebook multiple times,but they rejected it claiming that it didn't violate any of their "community guidelines"!! (go figure!!)
Please beware of this,and if you chance upon this ad,do report it straight away!
