How to keep you computer virus free

1. Install a recognized reliable antivirus software: Antivirus softwares scan every file in your computer for unusual alterings in the file size, suspicious email attachments and links and many other things. The most important step that you can take to keep your computer clean of viruses is installing an antivirus software. See Norton AntiVirus, Microsoft Security Essentials, NOD32 Eset Smart Security, AVG Free Edition...

2. Scan all your emails in your inbox: It is better to scan your emails and the attachments in your inbox before opening them. You should do this even if you trust the sender since malicious codes(like Trojan Horses) can make their way into your system by appearing to be from a friendly known sender.

How to extend laptop's battery life.

Once or twice a week we hear from people or our neighbors that their laptop's battery is not remaining charged for more than 30 or 45 minutes even though its been a few months since they bought it!

In fact, it is possible to get battery's life for two hours even after 2 years of buying the laptop(or the battery).

Here are some tips for you:

1. Keep the battery cool: Battery life time reduces if it is always hot. So it is very important to clean the vents to help the battery cool off! Dont you ever put the laptop on a pillow or a bed(since almost all vents are at the bottom of the laptop). Try using a cooler pad. (Flat surfaces are also efficient)
