is it worth upgrading to the $34 avg Pro version ?
From what I have read no. Also two other free antivirus programs that are solid.
1)
Avira AntiVir Personal - takes up less memory than AVG
2)
avast! Home Edition - takes up more memory than AVG but some believe has a better record at virus detection than AVG.
Spyware removers that you should consider:
1)
Malwarebytes' Anti-Malware - I use this one and its pretty good.
2)
Trend Micro HijackThis - this is a great little program. It scans the Registry and hard drive for spyware.
3)
SpywareBlaster - this is not a scanner at all but a program that Prevents spyware from being installed on your computer in the first place.
4)
Ad-Aware 2008 - I use this one as a back up because of problems with freezing up when scanning and update problems. solid though.
5)
SUPERAntiSpyware Free Edition - Just started using this one it seems pretty solid at detection.
