Clicked on a suspicious .exe file


Recommended Posts

Hello,

 

Today I clicked on a suspicious .exe file and am unsure whether my computer is infected. My UAC setting is set to default and I did not receive a notification when I double-clicked it. My computer was transferring about 30 GB of files in the background so the notification may have been slow/delayed. Regardless, I manually cut power to the computer after about a minute.

 

Am I at risk?

Not much showing...a couple of items need attention.

What was the file you clicked on????

=================================

Download the attached fixlist.txt to the same folder as FRST.exe/FRST64.exe.

Run FRST.exe/FRST64.exe and click Fix only once and wait

The tool will create a log (Fixlog.txt) in the folder, please post it to your reply.

===============================

Have you ran a scan with your Kaspersky Internet Security, if not please do so.

MrCharlie,

Had some weird behaviour today. My keyboard (laptop) became disabled. I realized that I could not input any keys - even after opening the Virtual Keyboard from KIS, still could not input text in my browser window or in renaming file names on my desktop. 

 

Then, after I closed Firefox (which had been running) I could use the keyboard again.

Malicious or not?

Cheers,

Vlad
