I have Windows XP and Guardian Antivirus 13.0. When installed the antivirus program made me download more than 100mb of DATA on my computer. Later my PC crashed and I lost all the data. I was wondering if some one can tell me where does it store the files so that I can take the backup and restore it later if my PC crashes. It is an automatic updata and I don't know where it stores the files. Please HELP. Thanks in advance.You could always check with the Guardian Antivirus WEBSITE but it is probably installed in Programs Files on your harddrive which is usually the C drive. My suggestion is to get RID of this AV and download and install an AV such as MicroSoft Security Essentials which is very effective and lite weight. The links are below.

Remember to only install one antivirus!

1) Avast! Home Edition
2) AVG Free Edition
3) Avira AntiVir Personal
4) Microsoft Security Essentials for Windows Vista\Windows 7 - 64 bit Download
4-a) Microsoft Security Essentials for Windows XP
5) Comodo Antivirus (Uncheck during installation "Install Comodo SafeSurf..", Make Comodo my default search provider" and "Make Comodo Search my homepage" if you choose this one)
6) PC TOOLS AntiVirus Free Edition

It is strongly recommended that you run only one antivirus program at a time. Having more than one antivirus program active in memory uses additional resources and can result in program conflicts and false virus alerts. If you choose to install more than one antivirus program on your computer, then only one of them should be active in memory at a time.
