Do not Run Antivirus Manually

Do you open the security suite and execute scans? The default Windows antivirus Microsoft Security Essentials and other such programs think that the system needs it and provides a warning else the computer would be at risk.  

These manuals are not what they are meant to be. If you have a relevant suite then it would do its job in the background without any external help. It would alert when there is any problem.

Manual scans are not necessary

Irrespective of whatever software you use it would always run in the background. Everything that runs on your system is monitored thereby ensuring that no malevolent processes are being executed. Whenever a new file is downloaded or the program is opened it would start its work in order to examine the file and compare it to viruses prior to allowing it to run. If the virus is downloaded the antivirus support software would notice without you having to scan anything. It would deal with the file without manually scanning. This is called real time protection or background scanning or on demand scanning and so on.

The application would check every malware that has arrived. You would not have to click any button as it has already started its work. Normally it runs once a week in the background without interrupting the user. 

When the manual scans should be executed

These scans are useful but it need not be opened regularly. Manual scans are still useful in some cases. When an Antivirus is first installed it would perform a full-system scan right away. This allows ensures that the system is in a clean state and the viruses would not loiter in unopened files on the hard drive. But when you would open the files they would be scanned again. 

Regularly the definition files of antivirus are updated. They contain a list of identified malware and the antivirus compares programs in order to see whether they match or not. There is a possibility that there is a virus in the executable file on your hard drive and the security program missed during the first scan manually. In case a virus definition has been added it would catch the dormant virus when the scan is performed. If you run the file which has the virus then it would be caught. 

At a time run a single antivirus support as implementing multiple ones can cause issues problems with your computer. In case you want to scan with a second application then do a manual scan with the second one instead of the background feature of scanning. 

Background Protection is preferable

In some programs background scanning can be disabled and perform manual ones only. A manual scan is like telling a security guard to search each and every part of the house for intruders. That way it is better to guard the house entrance so that the threats can be caught before even entering the house. When the program can hide itself as well as prevent the antivirus program, Windows Task Manager from running. This is called root kit.

The malware can be detected before the virus can run on your PC. So make use of automatic background scanning and not manual scans. Make use of automatic scans as it provides maximum protection.

Protect your USB from Viruses

Thumb drives or USB drives are popular among almost every PC user. Compact storage is offered to store projects, documents. The IT staff uses them to cart around tools. As these drives are popular and data is transferred between several systems frequently they are a soft target for hackers and intruders thereby spreading the infection.

In several firms USB drives are not allowed to be used as it can infect system easily. Silent applications are installed on workstations which would detect a drive when it has been inserted. That software would notify administrators.

Attackers would get infection through standard mediums with the help of bogus spam mail, exploits. The infection would not attack the system directly but would wait for any external device to be plugged in. After it has been plugged in, the virus transfers malicious code to device without knowing what is happening. The drive has become a tool which would transport the code he/she wants to the computer you plug the drive into may be the system in the office.   

Malicious code can steal personal information, sensitive documents, allow external access and even spread the virus to a system network. There are people who think that they have an encrypted flash drive so they are safe. It is wrong to think so. The encrypted ones are meant for data loss or theft. 

Digital photo kiosks are major distribution points for infections. If photo kiosk computers are infected it would be easy when thousands of people walk in and insert memory cards at Wal-Mart. What do you do to protect yourself against these activities? 

Now use the security features. Use sophisticated antivirus support. Use encryption as well as passwords on USB drive to protect data as well as ensure that you have details backed up in case you lost the drive. Just keep business USB drives as well as personal ones separate. Never use the personal drive on systems owned by your company and never plug USB drives that have corporate data into personal PC.

Maintain as well as use antivirus software and it updated. See to it that you use a reliable antivirus support. Use an antivirus, firewall and an anti-spyware software to make the system computer less susceptible to attacks. This can be done by using necessary patches. Never plug an unknown USB drive into your computer. In case you find an unclaimed USB drives give it to authorities. Never plug it into your computer to view contents or to identify the owner.

Some tech savvy users utilize virtual machine technology. If you use virtual machine software you can have a copy of an OS when checking email attachments, downloaded files and external storage devices for infections. If the virtual machine becomes infected then it can be restored easily from snapshot or an image. The data or even the device can be cured prior to being used on host operating system or any other computer.

The Web service behind this is software running on one or even more servers someplace on the Internet.

The other side of cloud antivirus

Some do argue that this lacks certain essential components for security and performance. Privacy invasion is a major concern due to the collected data from the computer. Prior to selecting such a product you can find out which data from the system could be part of the collective database. However it does have same concerns as that of the traditional antivirus program.  

Pros and Cons of Antivirus Software

Antivirus software is designed to protect the system from external as well as malicious programs like a spyware, Virus, Trojan, malware etc. There are several types of applications available in the market many of which also work even as an antispyware. 

But there are disadvantages with every program as well as impairs the performance of the machine and in several cases become allow. There are also few disadvantages associated with this Antivirus support. Sometimes it impairs the system as well as makes it slow. If you speak about a standard application then it should not be affecting the performance of the PC. 

Whenever we speak about increasing the performance of the PC it also comes to us the program being used and if it is heavy as well as occupy huge space then the user might even think to get rid of it from PC. However using it is highly important for security reasons as well as from the performance point of view. There are times when we see that even after getting rid of a system cleaner there remain parts of the uninstalled software and these can create issues like disrupting normal functioning of the PC and slow speed. Shutting down as well as freezing.

There are many available online both paid versions and freeware are difficult to understand while they are being installed. There are several such programs which follow signature based detection within an executable file. But there are chances where you would not find any such pattern. Normally antivirus support follows a heuristic approach. File emulation is something which is used by several security programs. It is also a heuristic technique.  

It is not easy to develop a protective program which cannot cure the system without even affecting PCs performance or without leaving PC. However one has to remember as well as follow a simple approach as far as how it should work is concerned. It should work in such a way that it does not slow down the performance and even damage normal function of the system.  

A virus is extremely dangerous to a system. Not all are fool-proof and without demerits. However the benefits prevail over the consequences of malware. There are times when these deny access to legal programs. If the system downloads a file or runs it properly, then it may be due to the one running in the background.
