Working on computer and seems to be being attack by something. Install super Antispyware and program will not run. Tryed Highjack this and program will not run. Looked for antivirus installed and cant find any but when trying to install AVG it say already have antivirus and to remove it. Have to find somewhere to start but wont let me . I can get on line with computer but unless I can get a starting point to start removing and detecting the attacks I dont know where to start. Tryed the mentioned programs in safe mode also but know help there either.
