When your computer starts acting strangely, you may have a virus. Many infections have similar symptoms, which can alert you to unwanted changes and software on your computer. The sooner you determine that you have a virus, the sooner you can remove it and get your computer back to operating at peak performance.
Instruction
1. Open your anti-virus program. Many viruses will prevent you from opening the program or performing a scan. If you can open it, run a scan. Any positive result means you have some sort of infection. However, many modern anti-virus programs will also look for spyware, which is a less serious threat.
2. Perform a Web search in your default search engine. Spyware can reset your home page and search engine, while some viruses will redirect you to websites other than the one that you clicked in search results. Is this especially true if you're trying to load websites that help you remove viruses.
3. Look for pop-ups. They might appear even when your browser is closed, and pop-ups are a sure sign of some sort of infection.
4. Look for unknown icons in your task bar or programs in your "Remove Programs" screen in your control panel. If you can't close a program or icon or have trouble opening your control panel at all, you may have an infection
.
5.Determine if your computer is running more slowly. Booting up or shutting down might take more time. Your computer may lag when you open programs, or you may experience delays when switching between programs

Note: Malicious software may actually pause as an anti-virus alert. Make sure you only respond to alerts from the protective programs you have installed
