I had this for a few months, and all I got was more problems with performance on my laptop. Eventually, I did some research, and found out this is a shady company to say the very least.
I bought and downloaded Zemana Anti Malware Removal, and every piece of malware they found was from Slimware driver Update. They quarantined the app and poof ... all my problems were solved. Stay away from Driver Update and all Slimware products.
Also if you call them to question them as to why when I scanned my computer with an anti malware app and all the malware that came up came from them, they still have the moxie to try and sell you additional products.
