Know if your machine is affected with virus,Trojans,etc. & Tips to protect your PC

The main reason that today a common man's PC is full of viruses and different kind of malfunctions is that the people ( YOU ) aren't aware whether you are infected or not. As every virus is programmed differently , it becomes very difficult to identify it.
Well however , I've come up with some symptoms of computing infection. They are :
1. Slow computer : Most of the virus are programmed for this purpose . Such virus increases your computer usage to around 100 % . When you check the task manager , it will show the computer usage to 100 % constant . So this is a point where you'll have to contact your computer man
2. Computer won't boot : If your computer has suddenly stopped booting, it is possible that some malware has modified your computer's system files. In such a situation, re-installing or repairing your operating system might be the only solution.

3. Unusual Network Traffic: If even after closing your browser and other applications that may use the internet, you see that your computer is still downloading or uploading anything, then your computer is possibly infected with some form of spyware that is either downloading other viruses to your computer or is uploading your private information to a remote computer. In case you use a WiFi connection , it is also possible that your neighbors are using your network.

4. Programs start automatically : Some viruses and adware automatically start strange programs on your computer in order to show unwanted advertisements or simply to frustrate users.

5 . Security Software Disabled: Most malware disable antiviruses and firewalls to prevent themselves from being detected. If only a single software stops working, it might be a specific software failure issue. If it is a general trend and almost every security software  is facing this issue, a virus infection is most likely.
 1 . Strengthen Your Password by Using Different Characters
Your password is a key that can unlock all passages for strangers to get access to your precious data; therefore, it is of paramount importance that you choose a password that is both complex and unpredictable. These days, experts advise users to pick passwords that contain alphabets, numbers and other characters. Also, the password should also be long enough. Passwords shorter than eight characters are considered unsafe.
2 . Prefer Wi-Fi over Broadband Internet
Over the years, experts have concluded that wireless internet much more convenient and reliable as compared to broadband internet connection in terms of data security. Before you pick an ISP for wireless connection, make sure that adequate firewalls and data security features are enabled.
3 . Use Encryption to Protect Your Data
Most people tend to underestimate the advantages of getting your data encrypted. Encryption involves a secret code that is used to switch your data into another format. There are various software programs that can be used to encrypt your data for extra protection. One of my favorite data encryption tool is TrueCrypt .
4 . Use Anti-Virus Programs
No one can deny the fact that despite all precautionary measures, the possibility of virus and bugs entering your system cannot be ruled out. Therefore, the use of anti-virus programs, both free and paid, becomes very crucial. There are many top anti-virus programs that are downloadable from the web for free.
