If 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"
- Disk Cleanup will scan your files for several minutes, then open.
- Click the "More Options" Tab.
- Click the "Clean up" button under System Restore.
- Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
- Click Yes, then click Ok.
- Click Yes again when prompted with "Are you sure you want to perform these actions?"
- Disk Cleanup will remove the files and close automatically.

• Avoid gaming sites
, underground web pages, pirated software sites, and peer-to-peer
(P2P) file sharing
programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections
, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads
and Flash ads
that install viruses, Trojans and spyware
. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories
