No. Viruses can even hack into your computer when it is turned off. It depends how strong your firewall and anti-virus protection units are.
Run your anti-virus program from the start menu.
It is a virus that is buried inside another program. SO when the program is run the virus does its thing. That is why a good virus detection software package is important and it is kept up to date.
It's actually really easy. Deactivate your virus program, run it, then turn your virus program back on.
Run the local scan and online scan with a antivirus program.
Has your computer become unstable or slow? Does your computer crash when you try to run a specific program or open a certain file? Do you see strange messages that a file or program cannot run. Are your icons odd or weird looking? Did your home page change and are you being redirected to a website? Does your Anti-Virus program refuse to run? All these are signs you have a virus.
It will, if you (or the virus) tells it to. However, even if a virus is transferred to another computer it will not run on that computer unless you or another program executes it, or unless the virus is able to exploit some security vulnerability in another program in order to run. A router will not transfer viruses to another computer on its own.
Run an update on you virus scan. Then do a complete scan on your system. Your anti virus program should be able to detect and clean or even quarantine the virus.
Download anit-virus software and run a whole computer scan and this will find the virus for you and get rid of it.
Generally speaking yes, most viruses are either.exe or screensaver programmes disguised as something else or part of another programme but they generally need to be run in order to do anything. Most antivirus programmes will alert you that a program is infected with a virus and prevent you from running it.
There is nothing wrong with having more then one anti-virus program installed on your computer. Not every virus is detected by every anti-virus program. It is actually a good idea to run more then one virus scanner.
That would be virus infected software. If you run a program with a virus, it can infect other files.
you will have to dowload some virus software like avg virus search on google for it and get a free download you can then run the program and it will find and delete any viruses
