What happens if McAfee VirusScan detects a file that it cannot clean?
When a virus infects a file, McAfee VirusScan cleans the virus and repairs the file. Trojans and worms behave differently. Trojans and worms are self-contained, and do not need to be part of another program or file to spread. The best way to eliminate these kinds of threats is to delete them. If McAfee VirusScan has detected a threat and is unable to delete it, the best thing to do is to run another scan to see if the file is still there. At times, even though McAfee VirusScan has deleted the malicious file, you may get a message that cleaning has failed. For best results, make sure that you have downloaded and installed the latest scan engine and DAT files. If you are running Microsoft® Windows® ME or Microsoft Windows XP, disable System Restore and scan again. Potentially unwanted programs (PUPs) may include multiple files that may plug into the operating system in such a way that simply deleting them can stop your system from working properly. We invite you to submit samples of PUPs
