I am using the demo versions of both Ewido and Trend Micro Anti Spyware. My PC is running XP Pro SP2. Looking at the features, both products seem to do very similar types of activities. If my interpretation is correct, then Ewido appears to be much *stronger* in Trojan detection and removal, while TMAS seem to be strong in Spyware detection and removal. Both programs have realtime scanning and protection modes. My question is: Is it an overkill to have both these products ? Am I *wasting* resources on two realtime scanning programs running in the background ? Are there *better* alternatives ? Thank you in advance for your assistance.
