First after having issues with CA Total Defence 12 i switched to MalwareBytes and Microsoft Security Essentials on each machine at different customers office and different configuratios. Some noticed their machines slowed down but i told them that with all the new spyware that antivirus and antispyware products have become larger and use more resources. i have asked this question here before and was told it was a good combination and i think it is. However, one software vendor told a client that MBAM was a hog and would slow a machine down. i know there are 2 products on the machines but it only seems a little slower in some cases. is MBAM a memory or processor hog?
Secondly, after installing the above products some machines were found to have spware but were successfully removed. i also stopped services and ran combofix. now most are slow. remove MBAM and the machines speed up. re install MBAM and the machine slows down.
Sorry for the long post but what is going on?
Almost all machines are XP Pro with SP 3.
