To help AntiVirus to protect your computer and speed it up, I recommend that you download, install and keep the following free programs:

  1. Keep Malwarebytes Anti-Malware, update it regularly or from time to time and run a Quick Scan weekly.
    Malwarebytes will detect and remove all traces of known malware. MBAM isn’t AntiVirus and it can NOT replace it.

  2. Keep MCShield Anti-Malware, the tool will be updated regularly and perform auto-checking for malware to each attached USB memory device.
    MCShield, has been designed as a lightweight scanner that’s smart enough to catch even new worms and work in fully automatic removal mode.

  3. It’s recommended to delete Temporary Files every once in a while. Run the tool and click on the Start button and TFC will begin to clean. Then restart the computer.
