Wasn't sure whether to put this here or in the security forum, but since it's not a 'problem' per se, I opted for here. Purchased a new Vostro 1500 laptop for my son in the Marines: Intel Core 2 Duo T5270 1.4GHz, 800Mhz, 2M L2 Cache 15.4 inch Wide Screen XGA LCD for Vostro 1500 2GB, DDR2, 667MHz 2 DIMM 128MB NVIDIA GeForce 8400M GS 160G 5400RPM SATA Hard Dr XP Home Edition, SP2 Integrated 10/100 Network Cardand Modem, for Inspiron Dell Wireless 1505 Wireless-N Mini-card The machine has no security software pre-loaded and I'd like to send him some instructions for downloading security software before his machine becomes a nightmare. My first suggestion would be AVG Free/AVG antispyware, then perhaps AdAware, SpywareBlaster and Spybot. Does anyone else have suggestions for making this machine as impenetrable as possible? He also has never had a laptop before (nor have I) so if there is anything we need to know pertinent to laptop security/maintenance could you offer your advice? Thank you, all.
