My understanding is that OA++ does not include real-time/on-access scanning for malware when on the internet or downloading from the internet. The OA++ scanner is an on-demand/on-execution scanner only. If the above is true, is it advisable to run an on-line/on-access Anti-virus/Anti-spyware application along with OA++? I have the following free versions, maintained in an in-active/off state, but updated daily and used for scanning at least once per week by each: A-Squared Free, Super Anti-Spyware (free), Malwarebytes (free). An recommendation of a real-time/on-access AV/AS to run in conjunction with OA++, if deemed necessary, will be appreciated.
