Is your PC infected with a virus? Don’t know how to get rid of viruses? Generally there are different clues that offer evidence that your OS might have serious virus infections such as sluggish system performance, browser redirection and suspicious email activity. Viruses can open doors to a world absolutely no person wishes to experience and it is essential to have an anti-virus application already present on the OS. Let’s go over various signals that enable us to recognize a possible virus infection even if you don't have an anti-virus.

1) Unresponsive Functions - If opening up selected functions provides no response, it certainly signifies there's a spyware infection that hinders the operation of software in normal mode. The more time a spyware or virus infects the system, the more applications it is going to disable and make unresponsive until all applications stop running.

2) Illegal Bookmarks and Unfamiliar Links - The inclusion of bookmarks, favorites, and links which start to show up in your internet browser can also be a huge warning that spyware has infected your PC. The spyware will make unusual and unknown links in the web browser's favorites and bookmarks options, visiting one of which triggers larger more serious problems. It is recommended then to run an anti-virus program to identify the spyware immediately.

3) Suspicious Toolbars - An additional integration of malware in your web browser are toolbars. You might recognize Yahoo, Google, and MSN toolbars that actually help, but the inclusion of certain suspicious toolbars in the browser is a sign that some malware is logging your browsing history and sending this information somewhere else.

4) Email Bombs - These email bombs are one of the final hints that malicious software has taken over the computer. Lots (and I mean lots) of unrelated email messages and explicit material inside your inbox, indicates that the computer is seriously infected and needs a scan and cleanup. This actually works both ways; the emails don't only enter into your inbox but will also send out automatically to all or any of your email contacts therefore it is recommended to check your sent messages in such a case.

5) Fake Warning Messages - While infected, the operating system will begin displaying weird and false warning messages stating that the Computer is infected with spyware and it advises using a particular anti-virus software to clean the Computer of the infection. But, this software is really a trick that furthers the infection with additional spyware to steal your personal data. None of these offers should be followed and should be responded by disconnecting the Computer from the web and running an immediate scan preferably with an updated version of an anti-virus. This symptom is serious and delaying cleaning at this point generally leads to even more serious issues.

6) Web browser Redirection & Pop-ups - A probable indicator that the Computer is infected is the internet browser being redirected to an unrelated website that essentially wants you to download some software or take a survey. When you enter a URL or go to a search engine, the same web page will pop up no matter what you type in. Pop-ups have the same resulting effect. You might have proper browsing, but before long the browser opens a pop-up window which has explicit or unrelated material that you never asked for or wanted to open up. Disconnect yourself from the net and run a thorough scan. NEVER click any of the pop-up windows, since it will undoubtedly make the spyware threat increase.

7) Sluggish System Performance - The most apparent thing that proves your operating system is infected is the slow performance of the operating system; software programs open slower and perform slower also. Opening a Word document may take 5 to 6 minutes and such, is a definite signal that your PC is infected.
