A new vulnerability uses antivirus software to carry out malware attack. The exploit works by taking advantage of the restore from quarantine function thats found on many antivirus solutions. The malware is thus relocated and moved from the quarantine folder to anywhere on the victims system, especially on a sensitive location on the system.
