I'm one of the new guys here, can someone teach me how to clean a computer with avast! free 6?
A good start would be "WITH AVAST"
is to make sure you are up to date with your definitions and program version. You can find out in the main menu when you click MAINTENANCE, then UPDATE.
Once that is completed click on REAL-TIME SHIELDS.
On the right hand side you will see an option for SETTINGS.
For my opinion and preferences, I have these as my settings:
Inside the new window of settings, down near the bottom on the left hand side click the Sensitivity and change the HEURISTIC to HIGH and check the PUP and software option below it. Click OK
Next in the main menu on the left hand side click on SCAN COMPUTER, then Scan NOW
You should see several of options at this point. You would want to look for FULL SYSTEM SCAN option. Just below that you should see MORE DETAILS. Just click on that and click on that blue link that says turn ON for PUPS.
Now all you need is to click on START!
(might take sometime for it to complete)
Hope this helped.
