This is the Trend Micro detection for files infected by PE_FUJACKS.BE-O. It may arrive on a system as a file downloaded by unsuspecting users while visiting Web sites.
Upon execution, it drops the file SPOCLSV.EXE, which is detected by Trend Micro as PE_FUJACKS.BE-O, in the %System%drivers folder. After successfully dropping its mother virus, the malware code of the infected file is removed, which consequently cleans the said file.
(Note: %System% is the Windows system folder, which is usually C:WindowsSystem on Windows 98 and ME, C:WINNTSystem32 on Windows NT and 2000, or C:WindowsSystem32 on Windows XP and Server 2003.)
