PC Tools offers some great software for online security and system utlility products. PC Tools offers Spyware Doctor, Registry Mechanic, Desktop Maestro, Privacy Guardian, File Recover, Spam Monitor, PC Tools Simple Backup and PC Tools AntiVirus.  I have not used most of the PC Tools products but I just had Spyware Doctor save my computer.  Spyware Doctor works great for spyware and malware repair.  It found and fixed my spyware problems that Malware Bytes could not.  I did try Malware Bytes which has been worked well in the past but this time around Spyware Doctor got it done for me.  I highly recommend spyware doctor and its not expensive.  PC Tools has lots of PC tools coupons for their various products and the Spyware doctor coupon is for an additional 20% off.
