I am not sure Spyvest is a programme I would want to use as it's on this list click here
Having said that, it's not for me to tell you what programmes to run on your computer.
If you are only using the one programme and you delete everything it finds, you are asking for trouble. Anti-spyware programmes give false positives from time to time so you need to know what you are deleting.
Adaware click here
Spybot click here
SpywareBlaster click here
Bazooka click here
click here for PestPatrol Research to help you identify any spyware you find and whether or not the processes, directories, and files associated with a particilar spyware are actually on your machine.
Also, it's a good idea to delete your cookies, (apart from any you specifically want to keep), before doing a scan.
(Spybot is currently showing DSO Exploit(5 items), and SearchForIt, (if SpywareBlaster is also on the machine), as false positives - it is still a very good programme, however).
