First, make sure you have an updated virus scan before you perform a full scan - Virus definition, patches, etc.
- if this doesn't fix your issue go to the next step below
Second, download the latest SDAT here http://www.mcafee.com/apps/downloads/security_updates/superdat.asp?region=us&segment=enterprise
Once your finished with the download, put the SDAT on a folder on drive C (or anywhere you want)
After you have copied or moved the SDAT, go to Command prompt by going to START > RUN > Type CMD > press ENTER
Go to the folder where you have copied the SDAT (e.g. C:\SCAN Folder\) and type SDATxxxx.exe /e (where xxxx stands for the latest version)
Wait for at least 3-5 Minutes and type in CMD, DIR (to see how many files are exisiting on the SCAN Folder) and check if the total number of files are 19 (including the SDAT)
Once the total files reached 19 then you are ready for a command-line scan
To initiate the command-line scan, type in the following:
scan.exe /clean /all /adl /analyze /program /unzip /winmem /report C:\SCAN Folder\report.txt /rptall
To see if the scan is finished, try typing CLS, if blank screen appears with only C:\> displayed then it means its finished.
You can check the report.txt for any viruses detected or viruses not deleted., etc
Also, you can do this on SAFEMODE w/ COMMAND PROMPT only to ensure that only the basic OS services are running as there are malwares that "hangs on" valid windows application or services to avoid detection of the AV.
