Updating anti virus software

02 Feb

If you're not careful, your computer can end up with a nasty virus that makes your files act oddly, crashes your computer, pops up bizarre messages, or worst of all, destroys your operating system.A computer virus is the most subtle of computer problems.

But unless you notice your computer acting oddly before the virus has done its worst damage, you may very well not know you have it until it's too late.But when you run the new program you just found, it can do anything from popping up a message to erasing your hard disk, as the rogue PKZIP utility really did.In either case, you have to actually launch the infected program or the trojan horse for it to infiltrate your system.These program codes have gone beyond mere annoyances with the worst kinds disabling your PC, but they have become portals for remotely perpetuating more sinister activity that can clandestinely hack into sites, mount denial of services or steal confidential and personal data for fraudulent financial gain at your expense. Among home PC users, you may think having to reinstall your OS after a virus or malware has brought it down is not really expensive as you lose just a day or two to reinstall your programs and rebuilding files, consider that in a business, you could actually lose millions.Just ask Choice Point when it took a million charge in 2005 after cyber criminals hacked into their systems and stole sensitive data from thousands of customers.
