All anti-spyware is not equal. Many do not remove spyware reliably. Some show false positives and push their products in a high pressure way. A few actually come bundled with spyware or malware. The Spyware Warrior Website has a list of rogue, suspect anti-spyware and websites. Check it out before you purchase and download any anti-spyware.
There are some excellent anti-spyware programs that are free for home users. See other postings in this blog. If you want help, Ducktoes will provide the anti-spyware for your computer(s). We make on-site visits to Calgary area homes and businesses. Call (403)287-0105 or e-mail me.
