Anti-virus softwares can be delicate and temperamental especially when there are two or more AV programs installed on one computer. Having two different AV programs installed simultaneously is a dog fight. Both AV programs will detect the other as malicious software and begin quarantining their files. Before you know it, both AV programs are malfunctioning.
To make sure this doesn’t happen you will need to take the proper precautions. Before installing any new Anti-Virus programs on your machines it is essential that you uninstall any existing AV from the system. More times than not, the new AV program will install successfully and scan without a hitch. However, sometimes the old AV program can leave bits and pieces in several different directories throughout your system. It is essential to search through the entire system for any remaining old AV data and remove it. AV files are most commonly found in the ‘C:Program Files”AV Service”‘, UserApplication Data directories as well as the registry editor.
