unable to delete temp files!! suspect- worm!!

[jamyang312]

i have some .tmp files like JET4ADD.tmp,JET5C00.tmp,JET410C.tmp and some dat files like Perflib_Perfdata_4f4.dat and many more and their size is 0 kb and also my connection is becoming slower!! my avast webshield also reported something like lsass exploit!!
what is happening? i suspect i have been infected with sasser worm!!

If anything doesn't work go to the command prompt( make sure u have closed WINDOWS) and try and delete them... this will work

As vandit said, delete the files from command prompt and restart...If the problem still persistes, try to get an exclusive tool from Norton at http:\\securityresponse.symantec.com

how do i delete at command prompt? please clarify.

 

[vandit]

restart ur pc..... when it just starts... repeatedly press f8 then select command prompt..
go to the temp directory and del them..

 

[ShekharPalash]

Use Unlocker to detect which programs are using those temp files... try unlocking and delete...

Use startup buddy to know which file is infected. Next safe start the system using F8 and delete the file.
