yes .. it needs it..
after having played with some reboot and "trash of hd" .. steam.exe is able to launch virus ..or at least to be used to do IT...
i was attacked by a ransomware right after playing it
like with the first attacks : the steamid [ the well known tool of "sovietos-coop gift" ] is making your pc easy to spot and find.. like a laser in a military plane...it "shoots only "the target" "
the more important to know is that there are tools able to stop the attacks .. but they should be installed before the attack starts.. because the encrypting "key" is stored in memory ...and stay there after reboot
some old solutions were able to read it and recover files but that no longer works..
so beside having a slow computer with very slow hds... i advise to read a lot about these "bastards" [that are able of writing asiat$$$$$]
i have mp4 files that were "encrypted" .. the audio is still playing but no more video.. i think the change are very minor on some giant files [ that are cool for "speed" ...] results are very bad when hd is having a lot of little files...
like those of a normal hl with tons of mod "extracteds.." [ little files are speed killers..] the virus was able to fuck 700 Go of 2 To of mp4 hd files but less than 4 with a partition of small files.. the process encrypts the files so it makes a copy ...
some backups or undellette tools are also usefull .. like the systeme restore..
i am not surprised so much..they use steam 24/7 to play games waiting the customers and "mapping" to kill time of waiting.... after being a chicken at parents 'home .. they are living by themselves in the "steam house"...
a bunch of mobs not able to do anything except stealing lying.. the bms team... the trouble happened and still happens with hospitals... where steamid is perfect to fool all .. it gets the network, it downloads and uploads a lot... plus it has GAMES [ NOT GurlZZZ ]
