if you are being honest and forthwith, dpak … that your anti-virus could not find anything … i'd suggest you start combing the internet for bug-cleaners. logic dictates this would start with websites such as mcafee 'n kaspersky 'n avast 'n avg … well, maybe not avg (their forum literally sux). then broaden your approach.
you are looking for the grungy 'n nasty bugs … exploits 'n ransomware 'n worms 'n trojans. you are also looking for a synthetic called "unitrix-exploit" … again, avast security knows this rodent intimately. once you understand the principle behind the sham … look inside your mind and imagine how the vice could be revised. this is what hackers do every day.
anti-virus and extended family is only as effective as the person behind the controls. i have no idea what your environment is, dpak … nor do i want. download some sentries and get the ball rolling … now! before you inadvertently infect others.
p.s. and you really should configure explorer to show file-name extensions.
