Is it Virus? (part 1)
It is not easy to tell if some virus has already gone its way to your computer. That’s why we strongly recommend that you install anti-virus software, or much better if you install more than one of it. The following are the common symptoms of a viral infection on your PC, although there are times that the following are not caused by a virus:
Your PC is running slower than usual. This can be due to too many processes and programs running at the same time or a problem with your network, but can also be caused by a virus infection.
Certain files or programs can not be opened. It is possible that a virus has erased parts of the files or programs that are necessary for the file to open or for the program to run.
