Maybe I worded it badly about MBAM, it is the IP blocking that I find too aggressive, otherwise it is a good bit of kit for a weekly scan
As to required tools then to be honest the free ones are generally just as good as the paid for programmes, just without all the bells and whistles. My security is Avast… and nothing else
You can set Avast to check for PUPS but you may find that the alert frequency may increase if you download a lot of programmes from the net
The recycle bin and temporary files folders are the usual hiding places for malware so they should be emptied frequently, I have IE set to delete all temp files on closure
Updating IE to version 8 will alleviate some of the problems http://www.microsoft.com/en-us/download/details.aspx?id=43
One Infoatom item remains because some numpty forgot to remove the relevant js files (me )
Warning This fix is only relevant for this system and no other, using on another computer may cause problems
