I think I Might Have Russian Trojan Fysbis on my computer

[Jan]

I live in Russia and despite being not a fun of Yandex I really doubt  they infects their users with any kind of trojans.

if they would do that they simply lost the market.

I'm sure the developers of Yandex offer it with good intentions.  But, as with many free services, there is often a catch - or a trade-off - data mining comes to mind.  Insofar as hacking, one would assume that Russian hackers would be most familiar with the vulnerabilities of Russian servers, emails and so forth, so it would make sense that if they're going to hack a system, they would hack what they know best.




I would suspect overheating, motherboard capacitors, power supply or something similar, i.e. start with memory test for instance.
It is always possible to reinstall the OS if the hardware is ok.



Thanks for the suggestions above.  I'll keep those in mind if reinstalling doesn't resolve the problems.
