Possible Malware

system · 2015-08-12T18:17:55.000Z

Hello ,

I’ve been experiencing some unusual slowdown, mainly programs being “slow to start”. Though lately it’s more or less fine. So I did some a boot-scan with avast! came came across this:

Main/C: Drive:
-Win32:WrongInf-D [Susp] from a zip file containing a video game that I’ve never opened

From an external drive:
-Win32:WrongInf-D [Susp]
-Win32:Dropper-EUT [Drp]
Both from [very old] files I’ve never accessed on this computer

All of them has been successfully quarantined. Though oddly both WrongInf-Ds came from video game related software, so it makes me wonder if it’s a false positive. Also I have ran boot scans in the past, but this is the first time I’ve decided to set the heuristics to maximum, and came across this. I’ve also did another boot scan using the same settings and it came up clean. All scans are done while disconnected from the network.

Also before this, I have used Firefox to [Yahoo] search up on some artists I’ve discovered, avast! popped a warning about a Trojan (forgot the name of it) and blocked it. Could some of it somehow gone through? And how did I get it just from search results? (I have uBlock, NoScript, and Avast on it as add-ons.)

Out of curiosity, what do these viruses do, and hopefully I didn’t inadvertently activated them.

And now the aswMBR file as instructed.

And I’ve noticed Windows Updater taking longer than usual. Maybe it’s because there are a lot of updates given the list of updates it just gave me. Should I update it now, or wait until this is resolved?

Nothing showing apart from Geekbuddy which is a waste of space

Hmm, alright. Unless there’s anything else, I guess I’ll do the Windows Update and run this month’s Malware Removal tool later on tonight. Then run another bootscan with avast! when I head off to sleep. Hopefully all this is simply paranoia on my part.

Why bootscan? … it does not give any better detection

system · 2015-08-12T20:46:15.000Z

Ah, it’s because the bootscan was how I got those detections before. I want to run again before I consider my computer safe or in the clear, unless I’m paranoid and this is overkill.

Bootscan may give detection of dormant files because it scanning a larger area, then quick scan that covers all area that activly running malware would use
You also have realtime protection, meaning any folder, file you access, read, save, copy … or whatever process your computer run is checked in realtime

Bootscan is to be used if you have problems removing a infection

Good to know, I’ve always thought boot scan is the better one since it’s used right at the start where the computer is most “dormant”.

After the Windows Update and reboot, my computer went into a CHKDSK for consistency. But in the end, after after one last quick scan with the Malware Remover, Malwarebytes, and avast!, nothing turned up. So unless there is something I overlooked or something in the logs posted, looks like I should be fine. Just gotta be cautious over the next couple of days. Thanks for your help, folks.
