Please someone help! I can't get rid of trojan-spy.win32@mx, and additionaly I can't access yahoo.com. I can only view my mailbox trough yahoo.uk or yahoo.de or other yahoo's. I am receiving quite often system alert regarding malware treats as "back door trojan". What does that mean exactly? I have Kaspersky IS 6.0, I also downloaded AVG Antivirus & Anti-Spyware 7.5. I have performed complete system scan, several times but the same problem occure time to time. Please someone help. Thanks in advance!
