It can repel unwanted cookies and Java applets and scan incoming and outgoing e-mail. Many of ,cheap laptop batteries, these products also include a personal firewall, which can provide even more protection. (We’ll talk more about firewalls later in this chapter.) There are lots of anti-virus software manufacturers to choose from, including Symantec and McAfee. Any of these can be trusted to do a good job at keeping your machine more secure.
Once installed, this software can be configured ,dell latitude d510 battery, to suit your needs. Generally, the default settings are fine, but you might want to set the application to look for and download new security definitions every night (instead of the default, which is generally every week) if you want extra security for your small business computers.

Tip: Don't Put New AV Software on Old PCs
There's a caution to keep in mind as you shop for anti-virus software: Products In that category are very "power hungry," In that they require a great deal of your PC's basic processing power. This is particularly true of the ,dell xps m1210 battery, majors like Norton and McAfee, which are constantly competing against one another by adding new features to their offerings. Both products have gotten so big and all-Inclusive that they can overwhelm an older PC with a more modest processor speed and memory complement. Here's my rule of thumb: Do not install the major AV products on PCs more than three or at most four ,dell Inspiron 1520 battery, years old.
Sometimes you can find older versions of the majors sold used online, but be careful: Some vendors like Symantec do not support older versions after a few years. Even If you Install Norton Antivirus 2001, for example, Symantec will not provide you with downloadable updates after the first period Is past, whether you're willing to pay for them or ,dell inspiron 4150 battery, not.
It's better to use one of the smaller anti-virus products, which have fewer features and thus place fewer demands on older PCs. The best of these Is probably AVG Antivirus from Grisoft. Go to www.grisoft.com. I've had it running on PCs going back as far as 1998, and while the performance hit is noticeable, it does not bring older PCs to their knees as Norton or MacAfee would.<
