During a scan, Ad-Aware will temporarily decompress files to scan their contents. Due to the fact that this antivirus provider also includes some detection of advertising (and/or spyware related) content, its resident scanner will detect the file that Ad-Aware is scanning. This is a normal function of the resident scanner. Thus, let Ad-Aware complete its scan, review the results, and then take what action is appropriate (whether to do nothing, ignore, or remove at your choice). Once this is completed, perform a scan with your antivirus to ensure that your system is free of virus infection.
