optiads-1.6.2[1].swf found by Defender from uTorrent

Pipppero2007 · 13 May 2017

Hi,

I need an advice and a little help.

Yesterday Defender alerted me with three malware named: "optiads-1.6.2[1].swf".

They were in the Explorer cache, "AppData\Local\Microsoft\Windows\INetCache\Low\IE".

Since I don't use a not sandboxed browser the only source of them should be utorrent:

uTorrent downloading virus (Exploit:SWF/Meadgive) - Troubleshooting - ÂµTorrent Community Forums

It should be an ad inside utorrent that rotate during the day. But a malicious ad.

Defender deleted them, and I clean the cache and the computer seem to be totally OK.

But, I need an advice... I have a restore point of the day before, that I would not use because Yesterday I made some changes in my OS.

IT's better that I use the restore point and uninstall forever utorrent or i can stay calm, since Defender found them and I can continue to use my pc without restore anything?

No, you do not need to use system restore, but you should get rid of utorrent, it is not what it used to be.

Many people would suggest staying away from torrents as the potential for d/l ing malware is pretty high. Even legit programs are likely to carry hidden installers that can put some unwanted items on your computer.

If you want a particular program, best to go to the official website/source to get it.

Staying away from utorrent is what i will do since now.

So i can definitely dont need to worry for that flash file caught by defender in cache?

I can be sure that a malware didnt dò something bad? A normal Defender full scan could be enough?

The infection was detected in Low folder, which stands for "sandbox" used by Windows, so it is OK.

You can scan with other malware scanner, just to be sure, it never hurts anyway.
