Why does having more than one virus scanning application on a computer cause a conflict?
As a general rule of thumb, you need only one of each. It’s what I do. A single, good anti-spyware solution, an anti-virus solution, and a single firewall and, in my opinion, you’re good to go. However, as I’ve noted elsewhere, there’s no single anti-virus or anti-spyware program that will catch all viruses or spyware. So there is a case to be made for having more than one. But if you do, you need to be careful because they can, and often do, interfere with each other. Anti-Virus Most anti-virus programs operate in two modes: •Scan: the utility examines memory and files on disk for traces of malware. This involves actually examining the contents each file for things that “look like” viruses. •Monitor: often referred to as “real time” monitor, the anti virus program is continually running and scans files as they are downloaded to your machine, notifying you nearly immediately if the file you just received contains something that looks like a virus. There’s nothing at all wrong periodica
