Your certainly welcome.
Now if there are no more problems, 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 recent 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.
. If your using the free version, use it as an on-demand scanner...no need to run at startup.
Although McAfee is as good as any other well known anti-virus program, it has become a resource hog that slows down your system especially if on dial-up or if installed on older systems without much RAM/slow CPU. McAfee requires numerous services and more than a dozen running files that use a lot of system resources.
Keep in mind that no single product is 100% foolproof
and can detect and remove all threats at any given time. The security community is in a constant state of change as new infections appear. Each vendor has its own definition of what constitutes malware and scanning your computer using different criteria will yield different results. The fact that each program has its own definition files means that some malware may be picked up by one that could be missed by another. Thus, a multi-layered defense using several anti-spyware products (including an effective firewall) to supplement your anti-virus
combined with common sense and safe surfing habits provides the most complete protection.
Using more that one anti-virus program is not advisable even if your using one of them as a stand-alone on demand scanner. Even when one of them is disabled, it can affect the other. Issues can arise when the active anti-virus detects the non-active one's definitions or quarantined files.
The primary concern with using more than one anti-virus program is due to conflicts that can arise when both are running in real-time mode simultaneously
. Anti-virus software components insert themselves into the operating systems core and using more than one can cause instability, crash your computer, slow performance and waste system resources
. When actively running in the background while connected to the Internet, they both may try to update their definition databases at the same time. As the programs compete for resources required to download the necessary files this often can result in sluggish system performance or unresponsive behavior.
Each anti-virus will often interpret the activity of the other as a virus and there is a greater chance of them alerting you to a "False Positive
". If one finds a virus and then the other also finds the same virus, both programs will be competing over exclusive rights on dealing with that virus. Each anti-virus will attempt to remove the offending file and quarantine it. If one finds and quarantines the file before the other one does, then you encounter the problem of both wanting to scan each other's zipped or archived files and each reporting the other's quarantined contents. This can lead to a repetitive cycle of endless alerts that continually warn you that a virus has been found when that is not the case.
Anti-virus scanners use virus definitions to check for viruses and these can include a fragment of the virus code which may be recognised by other anti-virus programs as the virus itself. Because of this, most anti-virus programs encrypt their definitions so that they do not trigger a false alarm when scanned by other security programs. However, some anti-virus vendors do not encrypt their definitions and will trigger false alarms if used while another resident anti-virus program is active. To avoid these problems, use only one anti-virus solution
. Deciding which one to remove is your choice. Be aware that you may lose your subscription to that anti-virus program's virus definitions once you uninstall that software.To protect yourself against malware and reduce the potential for re-infection, be sure to read:
