Many of us panic when an infection of the computer. We do not know what to do or where to begin. Sometimes, it may be easy, or may be very difficult to remove these infections, depending on the sophistication of the virus.
Should be the first step is to disconnect the internet computer and it disable any network of computers. If possible, try to back up critical files or data from an external hard disk or USB flash drive.
The next step is to use antivirus software to detect malware infection. Make sure you have the latest updates. You may not use the infected computer to update the anti virus software. Preferably, try to use another computer to download updates and copy updates from a CD or USB flash drive to prevent further spread of the virus. You can now do a full analysis of the system.
An excellent tool for emergency is to get a portable virus scanner to help analyze your infected computer. ClamWin free antivirus is a large popular portable antiviru cleaner having a high rate of detection of viruses and spyware. You can place on a USB flash drive and analyze any computer is infected. It should not be used as your daily antivirus program, since it did not have to access real-time scanning, but only use it in an emergency.
If for any reason whatsoever, your computer has a severe virus infection, try to restart your system in safe mode. Running in safe mode by tapping F8 just before the start, could help prevent the boot virus. After that, you can try to perform a full scan with antiviru software.
Another option is to format the hard disk. I would only use as a last option when things are corrupt and cannot be resolved. Do a full format and not a quick format, because some viruses can still reproduce. A good idea is to partition your hard disk. If your system is infected you probably do not format the entire hard drive, but only the partition infected if necessary.
There are a number of free antivirus and antispyware software programs to help protect your system. Avast Home Edition, Avira AntiVir Personal, Dr.Web CureIt, Spybot - Search & Destroy, SUPERAntiSpyware, Spyware Terminator are all free software. It is important to have more than one scanner because not all scanners can detect any.
If you are looking for a way to improve the security of your system, a firewall is a recommended suggestion. A firewall will monitor and limit your computer to internet connections and other users. It can also prevent programs access the internet without your permission.
