Windows 10: Everytime I go on Twitch, the Microsoft Defender finds a Malware in my Files.

So, this started to happen to me around 8 hours ago.Every time I go on Twitch.tv to watch some live streams, Microsoft Defender will find a Trojan:Script/Wacatac.B!ml malware in the cache files of the browser I used to watch. I've tried different ones like Firefox, Chrome and Edge, aswell. Each of them contained the same—supposedly malicious—data file.I haven't noticed any other website causing this problem, especially no other VoD/LiveStream platform. After the first Microsoft Defender warning I received, I uninstalled my main browser and deleted all data that was in reference to it to g

Windows Defender notification of malware detection

Hello,

Thank you for keeping us posted and we appreciate your continued patience on this issue.

At this point, I suggest you to update the Windows Defender program and check if it helps.

To check for new Windows Defender definitions manually:

• Open Windows Defender.
• Click the arrow next to the Help button, and then click Check for updates. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Also, check if the detection is of the same malware file or not. Again, see if it is any specific program or a file you try to access which triggers the detection.

Additionally, view the log in Event Viewer to check if the malware is removed every time it is prompted.

To open the Event Viewer. To do so, follow the below steps.

• Go to the Control Panel and choose to click on the
  Administrative Tools icon.
• The above action will open up a new window of the Administrative Tools where you will see the
  Event Viewer.
  

You can view Windows Defender "Operational" events in Event Viewer under Applications and Services Logs -> Microsoft -> Windows -> Windows Defender.

Kindly keep us posted, for us to be able to assist you further.

Thank you.

 

Windows Defender Fails Malware Test

Naw... I'll just stick by Windows Server 2003 SP #1 fully hotfix patched (& current on that note), for now @ least, & doing what I do, to get THIS kind of security analysis score:





I never suck in virus' either! The 2 the times I thought I did, the past 15 years now? They were my own fault (running 2 antivirus once, & another I don't know WHAT caused it, or I can't recall specifics anymore) in "false positives"!

Ever since I started implementing a BOAT LOAD of things ANYONE can do, if they take 45 min. - 1 hr. running, or doing:

• BELARC advisor

• Using some security & speed oriented .reg file hacks

• gpedit.msc (altering various policies for better security)

• secpol.msc (hardening default security policies)

• lusrmgr.msc (hardening default userrights)

• regedit.exe (registry hive ACL rights)

• explorer.exe (NTFS rights)

• Turning off java/javascript & ActiveX/ActiveScripting in browsers

• Using Tcp/IP ports filtrating (easy to do in IP properties)

• Turning off Services I do NOT use that may have holes

• AntiVirus (AntiVir, NOD32, AVG, or Norton Corporate 10.2 edition (my favs @ least - I keep 1 resident, & one other as a 2nd opinion))

• AntiSpyware program (I like AdAware & SpyBot + use both, 2nd opinion stuff again)

• SEVERAL AntiRootkit programs (GMER, AVG, BitDefender, BlackLight, Rootkit Buster, Rootkit Revealer, AntiRootKit, Rootkit Hook Analyzer, Sophos - all many doctors opinions from what I feel IS the biggest threat out there now, rootkits)

• + using a hardware NAT firewall in combination w/ a software firewall (ZoneAlarm used to be good, & the native Windows firewall isn't bad, except for noting outgoing packets)

• Keeping up on Microsoft security patches to the OS & programs from them I use

• Being SMART about not opening email attachments & also using TEXT or RTF as my email reading format too

• After trimming services I do NOT use (& even the ones I don't as well, set disabled or not), I secure them ALL, per this thread:

Securing Windows 2000/XP/Server 2003 services HOW TO

• Using adbanner blocking HOSTS files (adbanners have been found to hold malicious code more than a few times the past 4-5 years now mind you)

*HARD TO BELIEVE ON THAT NOTE OF ADBANNERS HOUSING MALWARES IN SCRIPT & MORE?

CHECK THIS, DATED TODAY 02/21/2007:

Microsoft apologises for serving malware

APC issue 540 (Christmas) is on sale now!

*Smile

* YOU DO ALL OF THAT? Yes, You CAN be safe online & use Windows, just takes a bit of work... 1 hr. implementing it all, & maybe another 1/2 hr. testing it (like when you secure services - I did a BIG list, but not every possible service under the sun, because I have not run them ALL!)

MS ships their Operating Systems 'generic' enough to run on anything FULL FUNCTION, right outta the box... this can be its 'problem' too!

APK

P.S.=> Funny thing is though, I don't think we'll EVER be "110% solid secure" unless we go OFFLINE... @ least not for another 5 yrs. or so & then I think we'll be REALLY close @ least!

Microsoft's taking the RIGHT steps, in the RIGHT direction in their apps & OS, & so are other vendors too... this is a GREAT trend!

Heck - funny thing is? Snort turned up a security hole the other day... a program you CAN use to defend yourself... mistakes & oversights get made is all, still now even.

Today? It's the "Wild West" still, not as bad as it used to be in the earlier days/decades, but still 'risky' to an extent... still in the Stone Age guys, you'll miss these days, when they are gone... apk
