 Hi, I am calling from Sistweek. It has been reported that your PC is a virus. I will have to connect to your PC to scan it and remove the virus. Please click on the link to download the software. Beware, this is a scammer impersonating Sistweek and trying to gain control over your PC. Under no circumstances should you download any software or click on any link suggested by this imposter. Remember, Sistweek software does not make any calls to any user regarding anything. Sistweek software cannot see if there are any errors on your PC and even cannot personally identify any of the users. Do not interact with anyone who calls you regarding issues with your PC. Always contact the OEM by visiting their website. You can also report any such callers or incidents to reportacistweek.com or in the comment section below. So that we can take it up with appropriate authorities. Thank you.
