Viruses are very common for computer users. They are found in every operating system but the frequency of virus threats on windows is very large. You can prevent yourself from viruses by taking some basic steps but for a virus attack of higher level you need an online computer support for complete virus removal from your computer. However, there are some suggestions from my side to prevent your computer from virus threats:
Use only one anti-virus program at one time because using two anti virus features results in cancellation of both.
Make sure that your computer has windows security updates installed and also do a regular update of your anti virus program. It helps in identifying new threats.
Never click banner ads or pop ups because most of them contain links to download viruses.
If you are not able to prevent your computer with the help of above points I strongly suggest you to use an online computer help for virus removal. A good company provides all the features for your computer safety like firewall configuration and security settings, setup and configuration of anti virus, proper assistance on usability options for anti virus, a complete scanning and quarantining of virus etc. I have faced a lot of dangerous virus attacks and whenever I took the help of a good remote computer support I got my problem solved at the instant.
