System Security 2009 is taking over my friend's dorm's computer. Hoping that someone can help me......
-Windows XP - HE.
-Kaspersky icon in bottom right corner but cannot be activated/opened. I can't tell if this is part of the infection or a genuine copy.
**Unfortunately I therefore cannot provide information on when this infection first appeared because it is a second-hand computer in a friend's dorm.
-The scam System Security 2009 "interface" opens immediately upon booting and can't be closed. The scamscan indicates that the computer is infected by a various worms and trojans. Clicking on it opens popups to buy anti-virus software.
-Multiple fake error messages pop up in the bottom right hand corner whenever I try to run executable processes: "WARNING! Application cannot be executred. The file ____.exe is infected. Please activate your antivirus software."
-Popups periodically open telling me that "System Security Firewall has blocked a program from acccessing the internet. Internet Explorer Internet browser is infected with the worm Lsas.Blaster.Keyloger" or that "Harmful software detected..........[Remove all] or [Continue unprotected]."
-First tried to install AVG because I couldn't figure out if there was any legitimate anti-virus software installed or not (it didn't work - see above error message).
-Then tried to run the online virus scans listed here (http://www.raymond.cc/blog/archives/2008/01/29/comprehensive-list-and-review-of-free-online-antivirus-scanners/
). I could get the BitDefender to work but it said it found no viruses. I can not get any of the others to work either because it will not let me update the JAVA appelets or because it will not let me run the executable files from the desktop.
-I tried renaming the executable files and changing the extension but the "WARNING!" alert still says this file is infected and blocks it from running.
Any advice would be greatly appreciated. Also, I am fairly computer illiterate so please be patient and simplified in your responses. THANKS!
