Unfortunately, in my job I see a lot of computers that have gotten a virus or malware and need to be fixed (and not just PC’s but Mac’s as well lately). While some infections are due to lack of adequate protection – up-to-date antivirus and antimalware/antispyware software, others are due to people falling prey to social engineered malware (fake links on facebook etc), or people accidentally clicking on things, or one of the ones I really dislike – a virus coming in through one of the mass forwarded emails.
It is a misconception that just because you have antivirus/antimalware software that it will protect you 100% – even the best software is hard pressed to protect a computer when someone allows something to come in by clicking ok, yes, or installing questionable software or downloading questionable files (yes, all of the people using limewire, frostwire, or torrent software – you all are at risk every time you download a shared file!). Many times a virus or malware will get onto a computer because someone has installed some ‘toolbar’, ‘searchbar’, screen-saver, coupon printer, rebate searcher, or other such program like those worthless ‘speed up my computer’ programs that are either badly written or are actually malicious and downloads other bad software behind the scenes. **Special note: Almost ALL of the speed up my PC programs are basically worthless and can often do much more damage to your computer than good. Anything that messes with the Windows Registry can damage your Windows installation if it remove the wrong things, and many of them do that!
So what can you do to better protect yourself and your computer from these nasties? Here is a short list of things that I always recommend following to eliminate the most common ways that a computer can get a virus, malware or spyware.
1. Never click on links from social networks such as facebook, or links in emails – regardless of what a link says it is, it can easily be made to hide something else. What you can do is right click on the link, select ‘copy shortcut’ then paste that into the address bar of your browser to see what it really is (or if you have the status bar in your browser enabled, you can often see it there) – if you don’t recognize the link or it looks suspicious – DON’T GO THERE!
2. Never open email attachments unless you specifically know that the specific person who sent you that specific email was sending you that specific attachement – too often people will get an email from a friend or family member that has an attachment and that attachment is a virus that a virus on their computer sent without them even knowing about it. If you don’t know what it is, and weren’t expecting it – DON’T OPEN IT!
3. Don’t download songs, software, videos etc from file sharing networks – when you use software such as Limewire, Frostwire, Vuze, or other torrent or file sharing software to download things you always take a big risk because you have no way of knowing where exactly the files are coming from, or if they have been altered – even a song can hide a virus or malware within it and it won’t activate until you play it. Also the majority of software ‘cracks’ or ‘activators’ have malicious viruses in them. Not to mention that downloading copywrited material is also illegal
4: Keep your antivirus and antimalware/antispyware software as well as your operating system software up to date! It is always important to update your system regularly as the software updates often carry fixes for security issues that have been found and without them you are much more vulnerable. Also update your OS to the latest version (yes, if you are still running Windows XP you might have to get a new computer, but XP is 11 years old and was never designed to handle today’s internet).
5: Beware programs like coupon printers, rebate searches, search toolbars, browser add-on’s, screen savers, and especially the fix all or speed up pc programs. Many times these programs are either malicous themselves or are so poorly coded that they make it much easier for bad things to get onto your computer – IF IT ISN’T FROM A TRUSTED SOURCE – DON’T INSTALL IT!
If your computer does get a virus, try to remove it with your antivirus/antimalware/antispyware software, or you can try to do a Windows system restore to a time before you got the virus (as opposed to a full computer factory restore which will wipe all your data).
