Guys this is my personal choice and believe me i have had a few rounds with spyware adaware and virusus..I use mwav or you can use e-scan the full product from microworld(as suggested by jpnyc),zonealarm pro(can be demanding at first and you have to have a little knowledge of pc,s to organize it with regards to permissions granted) and avg free edition..I have used them all but have found the last combination being the best one for me anyway..The following link http://antionline.com/showthread.php?t=275001 is the last time i had sh........Thanks to nihil and a few other good ppl here we were able to salvage most of my stuff..And before i forget NEVER USE THE INTERNET WITHOUT A FIREWALL!!!NB I have found that a lot of ppl switch them off for home use or lan gaming and never switch them back on!!so ya!!I rest my case..
