When an anti-virus quarantines a file by moving it into a virus vault (chest), that file is essentially disabled and prevented from causing any harm to your system. The quarantined file is safely held there and no longer a threat
until you take action to delete it. One reason for doing this is to prevent deletion of a crucial file that may have been flagged as a "False Positive
". If that is the case, then you can restore the file. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Quarantine is just an added safety measure
. When the file in the vault is known to be bad
, you can delete
it at any time.
If you were still infected, AVG would still be alerting you. Since there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one
. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back
" to a clean working state.The easiest and safest way to do this is
- Go to Start > Programs > Accessories > System Tools and click "System Restore".
- Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
- Then use Disk Cleanup to remove all but the most recently created Restore Point.
- Go to Start > Run and type: Cleanmgr
- Click "OK".
- Click the "More Options" Tab.
- Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
