Can I give you one valuable advice? Don’t fall for XP Defender 2013 and never pay for its license because, just like Win 7 Defender 2013, it is a rogue anti-spyware, which is actively spread on the Internet. In order to get victims out of their money, it reports about nonexistent viruses and threats, and then offers to remove them for money. What a wise way to get some money from unaware PC users, right?
Typically, this scamware uses Trojans for its secret infiltration that can easily be downloaded together with freeware, shareware, email attachments or video/audio codecs. As soon as it gets inside the PC, XP Defender 2013 sets itself to start once PC is rebooted by entering some registry entries of its own and starts showing up every time user starts using his computer. I can guarantee that you won’t miss its alerts and scanners that will additionally report about numerous viruses detected.
Before you believe these infections reported, remember that XP Defender 2013 has an empty virus data base, so all it is capable to report is your legitimate files. Instead of eliminating those ‘infections’, you must remove XP Defender 2013 from your PC by blocking its executables (i.e. files ending with .exe) and running legitimate anti-malware program.
