If you’re running XP, your computer isn’t going to self destruct on April 8, but if you use it to connect to the Internet, things might get a bit dicey. Microsoft issues periodic patches that shore up potential chinks in XP’s armor, but that all ends on April 8. Once new security holes are discovered by bad guys, they could be exploited over and over again by viruses and malware. Antivirus and antimalware software can help somewhat, but these solutions are generally more reactive than proactive. They won’t be able to thwart many (or any) fast-moving zero-day exploits.
