If you observe an abrupt decline in your computer’s performance after browsing through the Internet or opening a particular email attachment, it’s possible that your computer has been attacked by a malware such as a virus or a spyware. Most of the viruses break into your system either through the Internet or spam email attachments. However, it is possible to resolve this problem by using various security programs, which are easily available, and perform a full system scan to avert nasty malware attacks.

Given below are the steps to install and run security software on your pc that can help you keep it free from virus attacks.

Disconnect your PC from the Internet and network

You must immediately disconnect your pc from the Internet and network as soon as you notice its erratic behavior. This will help you prevent malicious programs from installing and propagating more malware files using the Internet and your network. It is worth mentioning here that such programs often spread over the network by pushing onto fully shared folders and generating mass e-mails.

Install a security program to ensure full protection of your system

After you have disconnected your pc from network and Internet, install the latest security program by following the steps described by the product manufacturer. After you have installed the software, connect to the Internet, update the software for the latest virus definitions, and complete the installation process. While buying a security program, ensure that you invest in the most advanced and up to date software version, which can combat the high-tech viruses of today.

Once you have installed and updated the security software, check whether all security features mentioned in the software are enabled and are working fine. An efficient security system allows you to modify the configuration settings as per your requirements. You may enable various add-on features on software such as parental control and spam blocker, which normally do not play a role in virus prevention.

Run a full system scan

After updating and configuring security program on your pc, it’s time to run a full system scan on all drives of your pc. It is advisable to run a scan even on external drives that you frequently use to perform additional tasks. Once the scan is over, review the report to check whether it has scanned all folders on your pc. If the report is clean, you may run the scan yet again to ensure that no malware remains on your system. If you don’t find any virus on your computer even after running the scan twice, this means your pc is having some other problem such as registry errors, software issues, or faulty hardware devices. In this case, you need to use registry cleaner and PC diagnostic utilities to identify and resolve these problems.

Delete the malicious files and programs

If the scan report indicates one or more malware, follow the instructions provided by your security program to get rid of it. The program may ask you to heal, delete, quarantine or restore certain files stored on your pc. In case the software reports that a critical application file or data file is infectious, you must ensure that you have a backup of these files before you choose to delete or quarantine them. If the software asks you to remove infected application files, you may have to reinstall them later.

Run the scan again until you do not get any errors.

After you have removed the infected files and applications from your system, you must run the scan again to ensure that infected files are permanently removed from your machine. You may need to rerun the scan until the report indicates no further threats. You must take a backup of your critical data as a regular practice so that your data remains completely safe from such attacks.

Other than running a full system scan at regular intervals, it is possible to prevent malware infections even in the future by allowing the security program to run in the background while using your pc. This provides real-time protection to your pc. Also, you must update antivirus software regularly with the latest virus definitions so that you are well-protected against any new viruses spreading across the Internet. It surely helps to be a vigilant user. Avoid visiting ambiguous websites and refrain from opening unsolicited emails. Other than using a security program, you must also use registry cleaner and PC diagnostics tools to ensure complete maintenance of your PC.
