Windows Service Packs Help Protect As Well
Ever wonder why the service packs are released periodically by the Microsoft Corporation? Well for one, they are also doing the same thing of protecting and upgrading their operating systems from new attacks that are developed everyday.
Anti-virus software is still needed but as far as stand alone operating systems are concerned, basic protection is still needed. Anti-virus software protects as well, but these should be pointed more towards the advanced issues such as malware and Trojans which are all over the web today. Most of them come from emails and websites visited and to make sure they don’t find their way into you computer, it would be best to be ready.
