otherwise you "could get into trouble". You could have a second AV program on your computer but NOT running, you could use it as an "on demand" scanner.
As Anti Virus programs are NOT good in finding malware\spyware - you need an anti spyware program. NOT ALL anti spyware programs find "everything".
There are GOOD FREE Anti Spyware programs.
Then there are "Preventative Scurity Programs" - have a look here:
I have used PC's for about 7 years, but anitvirus and antiapywear programs still confuse me. I have Norton 360, had Ad-Aware, have Spy Sweeper ( which is asking to update to antivirus software for $10) and a free version of AVG.
This is clearly overkill of some form, but I would appreciate some suggestions on how to get my hands around this mess. Thanks
