These are a few ways of how to check if there is any virus Attack on your PC:
Method 1 of 2: Monitoring Your Computer’s Performance
1 Check your hard drive activity. If you aren’t running any programs and your hard drive light is constantly turning on and off, or you can hear the hard drive working, you may have a virus that is working in the background
2 Time how long it takes your computer to boot up. If you start noticing that your computer takes significantly more time than usual to start, a virus may be slowing down the startup process.
- If you can’t log in to Windows, even with the correct log in information, a virus has most likely taken over the log in process.
3 Look at your modem lights. If you don’t have any programs running and your modem transfer lights are constantly blinking, you may have a virus that is transmitting data over the network.
Method 2 of 2: Keeping Tabs on Your Programs
1 Make note of program crashes. If your regular programs start crashing more frequently, a virus may have infected the operating system. Programs that take longer to load, or that perform extra slow, are also indicative of this.
2 Look for popups. If you have a virus infection, you may start seeing messages appear on your screen, even if no other programs are running. These can include advertisements, error messages, and more.
- Viruses can also change your desktop wallpaper without permission. If you find yourself with new wallpaper that you didn’t select, chances are you have a virus.
3 Be wary of granting programs firewall access. If you get constant messages about a program requesting access to your firewall, that program may be infected. You are receiving these messages because the program is attempting to send data through your router.
4 Watch your files. Viruses often delete your files and folders, or changes are made without your consent. If your documents are disappearing, there is a good chance that you have a virus.
5 Check your web browser. Your web browser may open new home pages, or not allow you to close tabs. Popups may appear as soon as you open your browser. This is a good sign that your browser has been hijacked by a virus or spyware.
6 Talk to your friends and colleagues. If you have a virus, your mailing list may be receiving messages that you did not send. These messages often contain more viruses or advertisements. If you hear that others are receiving these from you, you most likely have a virus.
7 Try opening the Task Manager. Press Ctrl+Alt+Del to open the Windows Task Manager. If you don’t have access to this, a virus may be blocking you from accessing it.
PREVENTION METHODS-
Using A Disk Defragmentation software or a good Antivirus with Online Virus detection System.
Well, I Personally recommend using McAfee Stinger. It has all the features of a good antivirus.
It also takes little disk space and RAM and has highest detection rates against threats.
