screenshotIf your browser keeps redirecting you to a website called BasicScan, you have a hijacker virus on your computer. BasicScan.com is a phony search engine that displays spam results, and it’s sometimes promoted as a browser toolbar. Every time you click on one of the phony search results, you earn money for the hackers behind this trojan. So don’t even try using the useless BasicScan search engine, because it’s all just a big scam.

And in the meantime, you may notice your computer acting strangely. Not only will your browser keep redirecting you to BasicScan, but you may also notice system slowdowns, and don’t be surprised if the BasicScan trojan invites a few of its buddies over for a badware soiree. Hopefully you will take care of this pest before that happens.

Do you just want your computer to act normally again? Here’s how to completely get rid of BasicScan.

DIY BasicScan Removal Instructions

Start by removing the above files. If you're not sure how to do this, refer to the instructions below.

Note: In any files I mention above, “%UserProfile%” is a variable referring to your current user’s profile folder. (Not an iEuphemism for muth@fugg@#*!@.) So if you’re using Windows NT/2000/XP/7, by default this is “C:\Documents and Settings\[CURRENT USER]” (e.g., “C:\Documents and Settings\NoahFence”).
