I really like free (reputable ) stuff. AVG & AVAST (& I think Anti-Vir) offer such with very frequent updates. Enjoy !!
I use the following to keep my self protected:
Zonealarm 5.5.094.000 (free)
Antispyware and adware (real-time):
SpywareGuard 2.2 & Spywareblaster 3.4 (both free)
Antispyware and adware (removers):
Ad-aware SE Personal 1.06 & Spybot-Search and Destroy 1.4 (both free)
GenDiskCleaner & Ccleaner & Windows Disk Cleaner.
I keep all of these GREAT AND AFFECTIVE free programs up-to-date every week. Plus i do a defrag every second week.
Am i now protected against any threats?? or do i need more??
